Definitions
- the present invention relates generally to an endovascular apparatus for the treatment of aneurysms or arterial blockages, and more particularly, to an endovascular apparatus having an expandable attachment device for securing the endovascular apparatus to an interior wall of a lumen
- An abdominal aortic aneurysm is an abnormal enlargement or “ballooning out” of the arterial wall of the aorta in a region that passes through the abdominal cavity, usually below the renal arteries and above the common iliac arteries.
- the aneurysm may also extend into the common iliac arteries.
- Such aneurysms are typically brought on by the weakening of the arterial wall from vascular disease.
- abdominal aortic aneurysms often do not cause pain, unless treated, an aneurysm may rupture causing a fatal hemorrhage in a patient.
- aortic aneurysms were treated almost exclusively by surgical repair. Specifically, the aneurysm would be resected and replaced by an artificial artery known as a prosthetic graft. Because of the substantial risks associated with such an invasive surgery, however, other treatments for aortic aneurysms have been proposed including endovascular grafting.
- Endovascular grafting involves the placement of a prosthetic graft within the lumen of the artery such that the graft spans the length of the aneurysm. In this manner the aneurysm can be excluded from the circulatory system rather than resected.
- the endovascular graft can be introduced into the vascular system percutaneously. Once the graft has been positioned at the site of the aneurysm it can be attached to the vascular wall both above and below the aneurysm using expandable attachment devices to prevent movement of the graft after deployment.
- the graft To introduce an endovascular graft percutaneously, the graft must be collapsible into a small profile for negotiating the vascular system. Upon reaching the site of the aneurysm the graft and its attachment devices can be expanded into a desired shape using an inflating balloon catheter or other actuator.
- expandable attachment devices have been proposed for securing an endovascular graft to an interior wall of a vessel most of which use stents with hooks or barbs to penetrate the intima of the vessel. None of the proposed attachment devices, however, have been found to be ideally suited for use with an endovascular graft.
- an endovascular apparatus having a new expandable attachment device having a new expandable attachment device.
- the new attachment device ideally should be small with a low profile and should expand to many times its initial diameter. It also should exert enough radial force when expanded to fix into the aorta and thereby reduce blood leaks around the apparatus.
- an expandable attachment device for securing an endovascular apparatus to an interior wall of a lumen.
- the expandable attachment device may include a plurality of telescoping arms that are joined together to form an expandable ring. This ring may function similarly to stents.
- the expandable attachment device may be attached to an endovascular apparatus for the treatment of aneurysms or blockages, such as a graft or stent, or to a heart valve and may include barbs, hooks, or other fasteners about its perimeter for attaching to the interior wall of a lumen. Because the attachment device can be collapsed to a size that can be fed through a vessel, the attachment device and an associated endovascular apparatus can be deployed percutaneously in a patient. Once positioned at the site of an aneurysm or arterial blockage, the telescoping attachment device can be expanded to hold the endovascular apparatus in place adjacent the inner lumen wall.
- an endovascular apparatus for treating aneurysms or arterial blockages using a minimally invasive technique.
- the apparatus includes a tubular sleeve having a cranial end and at least one caudal branch. If the tubular sleeve includes a first caudal branch and a second caudal branch then the tubular sleeve is shaped like an upside down “Y.” Accordingly, for the treatment of abdominal aortic aneurysms the cranial end may be positioned in the infrarenal aorta, the first caudal branch may be positioned in one of the common iliac arteries, and the second caudal branch may be positioned in the other common iliac artery.
- the tubular sleeve may be made from materials conventionally used to make endovascular grafts including synthetic fabrics or films, DACRONTM or expanded polytetrafluoroethylene (ePTFE) so as to define a lumen and so as to be collapsible during percutaneous insertion into a patient's vascular system.
- materials conventionally used to make endovascular grafts including synthetic fabrics or films, DACRONTM or expanded polytetrafluoroethylene (ePTFE) so as to define a lumen and so as to be collapsible during percutaneous insertion into a patient's vascular system.
- the endovascular apparatus further includes an expandable attachment device attached to the cranial end of the tubular sleeve for securing the apparatus to an interior wall of a vessel above an aneurysm.
- the expandable attachment device comprises a plurality of telescoping arms that are attached to form an expandable ring. Each telescoping arm is similar to an expandable presentation pointer. Alternatively, each telescoping arm may function like an accordion. Accordingly, during percutaneous insertion of the endovascular apparatus into a patient, the attachment device can be collapsed into a small profile. Once the apparatus is positioned at the site of the aneurysm or blockage, the expandable attachment device can be expanded to hold the endovascular apparatus in place adjacent the inner lumen wall. Fixation components may be positioned around the perimeter of the attachment device and may be partially embedded in the inner wall of the vessel to secure the attachment device.
- the plurality of telescoping arms may be made from materials suitable for use in the human body including stainless steel, plastic, or an alloy of nickel and titanium generally known as NITINOLTM.
- NITINOL is commonly used in the manufacture of medical devices that are to be deployed in a compressed state through a catheter because of its unique thermal memory properties.
- a NITINOL part may be manufactured in a first condition and then cooled and compressed into a second condition. When heated to the body temperature of the patient the NITINOL part will expand to its original first condition.
- one or more expandable attachment devices may be attached to the one or more caudal branches of the tubular sleeve for securing the one or more caudal branches to the interior of the vessel wall.
- an endovascular apparatus comprises tubular sleeve having a central lumen with a cranial end portion, a first caudal branch, and a second caudal branch.
- An M-stent is attached to the cranial end portion of the tubular sleeve extending circumferentially around the tubular sleeve to hold the sleeve open and secure the sleeve to a wall of a vessel.

No. 10/624,864, filed Jul. 22, 2003, which in turn claims priority to U.S. Provisional Application No. 60/397,745, filed Jul. 22, 2002. Each of the aforementioned priority applications are hereby incorporated by reference in its entirety.
- 1. Field of the Invention
- The present invention relates generally to an endovascular apparatus for the treatment of aneurysms or arterial blockages, and more particularly, to an endovascular apparatus having an expandable attachment device for securing the endovascular apparatus to an interior wall of a lumen
- 2. Description of the Related Art
- An abdominal aortic aneurysm is an abnormal enlargement or “ballooning out” of the arterial wall of the aorta in a region that passes through the abdominal cavity, usually below the renal arteries and above the common iliac arteries. The aneurysm may also extend into the common iliac arteries. Such aneurysms are typically brought on by the weakening of the arterial wall from vascular disease. Although abdominal aortic aneurysms often do not cause pain, unless treated, an aneurysm may rupture causing a fatal hemorrhage in a patient.
- In the past aortic aneurysms were treated almost exclusively by surgical repair. Specifically, the aneurysm would be resected and replaced by an artificial artery known as a prosthetic graft. Because of the substantial risks associated with such an invasive surgery, however, other treatments for aortic aneurysms have been proposed including endovascular grafting.
- Endovascular grafting involves the placement of a prosthetic graft within the lumen of the artery such that the graft spans the length of the aneurysm. In this manner the aneurysm can be excluded from the circulatory system rather than resected. Using a catheter as a deployment device, the endovascular graft can be introduced into the vascular system percutaneously. Once the graft has been positioned at the site of the aneurysm it can be attached to the vascular wall both above and below the aneurysm using expandable attachment devices to prevent movement of the graft after deployment.
- To introduce an endovascular graft percutaneously, the graft must be collapsible into a small profile for negotiating the vascular system. Upon reaching the site of the aneurysm the graft and its attachment devices can be expanded into a desired shape using an inflating balloon catheter or other actuator. A variety of expandable attachment devices have been proposed for securing an endovascular graft to an interior wall of a vessel most of which use stents with hooks or barbs to penetrate the intima of the vessel. None of the proposed attachment devices, however, have been found to be ideally suited for use with an endovascular graft.
- Accordingly an endovascular apparatus having a new expandable attachment device is desired. The new attachment device ideally should be small with a low profile and should expand to many times its initial diameter. It also should exert enough radial force when expanded to fix into the aorta and thereby reduce blood leaks around the apparatus.
- In a first aspect, an expandable attachment device for securing an endovascular apparatus to an interior wall of a lumen is provided. The expandable attachment device may include a plurality of telescoping arms that are joined together to form an expandable ring. This ring may function similarly to stents. The expandable attachment device may be attached to an endovascular apparatus for the treatment of aneurysms or blockages, such as a graft or stent, or to a heart valve and may include barbs, hooks, or other fasteners about its perimeter for attaching to the interior wall of a lumen. Because the attachment device can be collapsed to a size that can be fed through a vessel, the attachment device and an associated endovascular apparatus can be deployed percutaneously in a patient. Once positioned at the site of an aneurysm or arterial blockage, the telescoping attachment device can be expanded to hold the endovascular apparatus in place adjacent the inner lumen wall.
- In a second aspect, an endovascular apparatus is provided for treating aneurysms or arterial blockages using a minimally invasive technique. The apparatus includes a tubular sleeve having a cranial end and at least one caudal branch. If the tubular sleeve includes a first caudal branch and a second caudal branch then the tubular sleeve is shaped like an upside down “Y.” Accordingly, for the treatment of abdominal aortic aneurysms the cranial end may be positioned in the infrarenal aorta, the first caudal branch may be positioned in one of the common iliac arteries, and the second caudal branch may be positioned in the other common iliac artery. The tubular sleeve may be made from materials conventionally used to make endovascular grafts including synthetic fabrics or films, DACRON™ or expanded polytetrafluoroethylene (ePTFE) so as to define a lumen and so as to be collapsible during percutaneous insertion into a patient's vascular system.
- The endovascular apparatus further includes an expandable attachment device attached to the cranial end of the tubular sleeve for securing the apparatus to an interior wall of a vessel above an aneurysm. The expandable attachment device comprises a plurality of telescoping arms that are attached to form an expandable ring. Each telescoping arm is similar to an expandable presentation pointer. Alternatively, each telescoping arm may function like an accordion. Accordingly, during percutaneous insertion of the endovascular apparatus into a patient, the attachment device can be collapsed into a small profile. Once the apparatus is positioned at the site of the aneurysm or blockage, the expandable attachment device can be expanded to hold the endovascular apparatus in place adjacent the inner lumen wall. Fixation components may be positioned around the perimeter of the attachment device and may be partially embedded in the inner wall of the vessel to secure the attachment device.
- The plurality of telescoping arms may be made from materials suitable for use in the human body including stainless steel, plastic, or an alloy of nickel and titanium generally known as NITINOL™. NITINOL is commonly used in the manufacture of medical devices that are to be deployed in a compressed state through a catheter because of its unique thermal memory properties. For example, a NITINOL part may be manufactured in a first condition and then cooled and compressed into a second condition. When heated to the body temperature of the patient the NITINOL part will expand to its original first condition.
- In another aspect one or more expandable attachment devices may be attached to the one or more caudal branches of the tubular sleeve for securing the one or more caudal branches to the interior of the vessel wall.
- In one aspect, an endovascular apparatus comprises tubular sleeve having a central lumen with a cranial end portion, a first caudal branch, and a second caudal branch. An M-stent is attached to the cranial end portion of the tubular sleeve extending circumferentially around the tubular sleeve to hold the sleeve open and secure the sleeve to a wall of a vessel.

FIG. 17 is a schematic illustration of a telescoping catheter for percutaneous introduction of an endovascular apparatus into a body lumen. - An
endovascular apparatus 10 according to a first aspect is shown inFIG. 1 . Theendovascular apparatus 10 includes atubular sleeve 12 having acranial end 14, a firstcaudal branch 16, and a secondcaudal branch 18. In other embodiments, termed “uni-iliac” devices, thetubular sleeve 12 may include only a single caudal branch. The tubular sleeve may be made from DACRON, ePTFE, peritoneum, fascia, or other common graft material so as to form a flow path for by-passing an aneurysm. - The
endovascular apparatus 10 further includes a firstexpandable attachment device 20 attached to thecranial end 14 of thetubular sleeve 12, a secondexpandable attachment device 22 attached to the firstcaudal branch 16 of thetubular sleeve 12, and a thirdexpandable attachment device 24 attached to the secondcaudal branch 18 of thetubular sleeve 12. Theexpandable attachment devices holes 26 which may be sewn or sutured to thetubular sleeve 12. Alternatively, in lieu ofholes 26, the expandable attachment devices can be woven into the sleeve. - In another embodiment, the
endovascular apparatus 10 may include a fourthexpandable attachment device 28 that is attached to the firstexpandable attachment device 20 bysupport columns 30. The fourthexpandable attachment device 28 may be positioned above a patient's renal arteries, superior mesenteric artery or celiac artery. Thesupport columns 30, which may be made from NITINOL or stainless steel, may provide columnar support and strength for theendovascular apparatus 10 while permitting blood flow to arteries located between the firstexpandable attachment device 20 and the fourthexpandable attachment device 28. - The
support columns 30 may be either wires or tubes. If tubular, thesupport columns 30 may also be telescoping. For example, in another embodiment depicted inFIG. 14 , thesupport columns 31 may comprise a plurality of incrementally sized segments that are slideably engaged and fit within one another. Thus, in this embodiment theendovascular apparatus 10 may be inserted percutaneously into a vessel with thesupport columns 31 contracted such that the axial distance between the firstexpandable attachment device 20 and the fourthexpandable attachment device 28 is reduced. During deployment of theendovascular apparatus 10 thesupport columns 31 may be expanded, thereby permitting the firstexpandable attachment device 20 to be positioned below the renal arteries while the fourth expandable attachment device is positioned above the renal arteries. In yet another embodiment, shown inFIG. 14 , thetubular support columns apertures 33 such that the adhesive can escape thesupport columns endovascular apparatus 10 to the wall of a vessel. - As illustrated in
FIGS. 2A-2D , theendovascular apparatus 10 is collapsible for easy insertion and navigation through a patient's vascular system using a catheter. Particularly, as illustrated inFIG. 2A , theattachment devices attachment devices sleeve 12 against the wall of a vessel. - The
endovascular apparatus 10 according to a second aspect is shownFIG. 3 in which thetubular sleeve 12 is supported bysupport columns 32. Thesupport columns 32 may attach the firstexpandable attachment device 20 to a fifthexpandable attachment device 34. Likewise, thesupport columns 32 may attach the second and thirdexpandable attachment devices expandable attachment device 34 which may be located at the juncture of the firstcaudal branch 16 and the secondcaudal branch 18 of thetubular sleeve 12. In addition thesupport columns 32 may be sewn or sutured to the exterior of thetubular sleeve 12. This may provide continued columnar support throughout theendovascular apparatus 10 to prevent migration within the vessel. Thesupport columns 32 may be telescoping as described with respect toFIG. 14 . - Referring to
FIG. 4A , anexpandable attachment device 20 according to a first aspect is shown in a fully collapsed state. Theattachment device 20 includes a plurality offixation components 36 positioned about the perimeter of thedevice 20. Aport 38 is located at the center of theattachment device 20. Theport 38 is sized so as to receive a balloon or other actuator during deployment. The balloon may be inflated to expand theattachment device 20 after insertion into a vessel.FIG. 4B shows theattachment device 20 in a partially expanded state.FIG. 4C shows theattachment device 20 in a fully expanded state. While in a preferred embodiment, the fixation component can have angular corners, in other embodiments, the fixation component can have curved, rounded, or ovoid edges. Similarly, the entire corner or edge of each fixation component need not be the same shape throughout the length of the edge or corner. - Referring to
FIG. 4C , atelescoping arm 40 is used to attach eachfixation component 36 to anadjacent fixation component 36. Thetelescoping arm 40 may be pivotably attached to afixation component 36 at one or both ends of thearm 40. Atelescoping arm 40 is made up of a plurality ofsegments 42. Thesegments 42 may be in slideable contact with one another and may be incrementally sized so as to fit within one another. For example, eachtelescoping arm 40 may be constructed from what is referred to generally as “nested tubes.” When thetelescoping arms 40 are fully extended theattachment device 20 may resemble a polygon havingfixation components 36 located at its vertices. Thefixation components 36 may include barbs or prongs 67 (shown inFIG. 8 ) for fixation to a vessel wall. In another embodiment shown inFIG. 16 , thetelescoping arms 40 may contain an adhesive and include ports orapertures 41 such that the adhesive can escape the telescoping arms upon deployment to assist in securing theendovascular apparatus 10 to the wall of a vessel. - As one of ordinary skill might appreciate, the attachment device may take variety of shapes depending upon the configuration of the
telescoping arms 40 and thefixation components 36. For example, referring toFIGS. 12A-D , thetelescoping arms 40 may be positioned in a single plane. Alternatively, referring toFIGS. 13A-T , thetelescoping arms 40 may be positioned in multiple planes in, for example, what is referred to herein as an “M configuration.” One possible advantage of the M configuration is that it may produce superior radial force for holding the attachment device in position. In addition, the M configuration may produce the same ratio of expansion (i.e., the ratio of the final outer diameter of the attachment device in its expanded state to the initial outer diameter of the attachment device in its collapsed state) as the “single plane configuration” using fewer parts. -
FIG. 13U depicts multiple “M configuration” attachment devices on an endovascular apparatus. - To keep the
telescoping arms 40 in their final extended state after deployment in a vessel, a one-way latch may be used to lockadjacent segments 42.FIG. 5 shows onepossible latch 44, in a first position, for locking the telescopingarms 40. Thelatch 44 may consist of a one ormore grooves 46 associated with afirst segment 48 and atooth 50 associated with a second,adjacent segment 52. As thetelescoping arm 40 is expanded, thesecond segment 52 moves in a first direction A relative to thefirst segment 48. Thetooth 50 and thegrooves 46 are aligned so as to engage when thetelescoping arm 40 is extended. Once thetooth 50 engages agroove 46, as shown inFIG. 6 , thesecond segment 52 may not move in a second direction B relative to thefirst segment 48. Accordingly, thetelescoping arm 40 is free to extend but may not collapse once extended. Of course other one-way latches may be used to lock thesegments 42 of the telescopingarms 40.FIG. 7 illustrates one possible cross-section of asegment 42 of thetelescoping arm 40. This “rail” design permits room for sliding and positioning of a one-way latch, like the one shown inFIG. 5 , betweensegments 42 shown inFIG. 4 . -
FIG. 8 shows theendovascular apparatus 10 according to a third aspect. In the embodiment shown inFIG. 8 , theendovascular apparatus 10 includes a double-expandable attachment device 60 in the place of the firstexpandable attachment device 20. The double-expandable attachment device 60 comprises an upperexpandable attachment device 62 and a lowerexpandable attachment device 64 which are separated by and attached to an o-ring seal 66. Theupper attachment device 62 is angularly offset from thelower attachment device 64 so that thefixation components 36 of each are offset. Thefixation components 36 may include prongs orbarbs 67 to aid in securing theexpandable attachment devices attachment device 60. The lowerexpandable attachment device 64 may be attached to thetubular sleeve 12. The upperexpandable attachment device 62 may be attached to the fourthexpandable attachment device 28 bysupport columns 30. - Referring to
FIG. 9 , theendovascular apparatus 10 according to fourth aspect is shown. In this embodiment a plurality of “M springs” 68 are attached to thecranial end 14 oftubular sleeve 12 as graft expanders in order to hold thetubular sleeve 12 open. In this manner the M springs 68 may reduce leakage around the perimeter of thetubular sleeve 12. M springs 68 may also be used to hold the caudal ends 16, 18 of thetubular sleeve 12 open. In the embodiment shown inFIG. 9 , the M springs 68 are not attached to thesegments 52 of thetelescoping arms 40 and are located on the exterior of thetubular sleeve 12. In another embodiment, the M springs 68 may be located on the interior of thetubular sleeve 12 or attached to thefixation components 36. Of course, in place of the “M springs” 68, springs in the shape of a “V” may be used. Alternatively, in another embodiment depicted inFIG. 15 , the M springs 68 may be replaced by telescopingarms 40 in an “M configuration.” -
FIG. 10 illustrates a typical abdominalaortic aneurysm 70 located in theinfrarenal aorta 71. Theinfrarenal aorta 71 is that portion of theaorta 72 located below therenal arteries FIG. 10 , abdominal aortic aneurysms typically occur below therenal arteries iliac arteries iliac arteries endovascular apparatus 10 may be used to treat or repair an abdominalaortic aneurysm 70, like the one shown inFIG. 10 , by excluding the weakened aneurysmal aortic wall from pressurized and pulsatile flow. In addition, theendovascular apparatus 10 may be used to treat aneurysms or blockages located in other body lumens such as the thoracic aorta, iliac arteries, subclavian arteries, urinary tract, bile tract, intestinal tract, etc. - The
endovascular apparatus 10 may be deployed at the site of an aneurysm percutaneously using acatheter 82 like the one shown inFIG. 11 . Thecatheter 82 may have anIV port 84, asheath 86 and anintroducer 88 which can be withdrawn within thesheath 86. Using thecatheter 82, the device can be introduced percutaneously through either of the femoral arteries. As shown inFIG. 17 , using a “nested tube” design similar to the one utilized by thetelescoping arms 40 of theattachment device 20, thecatheter 82 may also be made to be telescoping. - During deployment the first
