Definitions
- This invention relates generally to intravascular stents, and more particularly to intravascular stents that include a plurality of cavities formed on a surface of the stent and are coated with a restenosis inhibiting agent.
- the percutaneous balloon angioplasty and stent implant procedures have become the dominant non-surgical revascularization method of the atherosclerotic stenosis, or obstruction, of the vascular lumen, and particularly in the coronary vascular system in the heart.
- the restenosis rate after angioplasty has been as high as 25-45% in the first time clinical cases.
- the restenosis has been reduced significantly. Even so, the restenosis rate after stent implant is reported as 10-25% range depending on the condition of the vessel stented or what specific stent was used, requiring a need for further restenosis reducing measures after intravascular stenting.
- the local drug therapy appears be a very promising method for the future, as better pharmaceutical, chemical or biogenetic agents are developed and became available.
- Some research data both from animal tests and human clinical studies, indicate that there are evidences of suppressing restenosis after stent implant when certain growth blocking pharmaceutical agents available today are used to coat the stent.
- certain surface modifying materials coated on the surface of the stent may be beneficial by it alone or in combination with growth suppressing agent, in reducing restenosis rate.
- the drug or substance should be locally attached or coated on the stent and in sufficient amounts. However, attaching or coating a sufficient amount of a substance or drug on the coronary stent is not so easy a proposition.
- Coating a drug or an agent on the surface of the stent has a demanding problem of enough volume of such substance coated on the small surface areas of stent struts, without increasing the physical width or thickness of stent struts. This demand directly conflicts with the metal fraction issue of the stent. If the width (and lesser degree the thickness) of stent struts is increased in order to widen drug coating surface areas, it would have an elevated deleterious foreign body effect of the increased metal fraction of the stent, which would promote restenosis.
- an ideal stent particularly the coronary stent
- An ideal stent requires an ideal balance of numerous different stent features built into the stent.
- One of the many requirements of a coronary, or any vascular stent, is to keep the metal fraction of the stent low. This means that drug coating is a very demanding task. Enough amounts of a drug or agent should be coated on the miniscule surface areas of the stent struts, in order to have the desired drug results of reducing restenosis.
- An average stent, particularly a coronary stent will have problem of providing desired amount of drug-retaining capacity on the surface areas of the stent struts.
- the main invention of this application is not an invention of the stent itself.
- the present invention is the particular measures designed to increase drug coating or attachment capacity of a stent by adding exposed surface areas or reservoir capacity of the stent, without increasing the width or thickness of the stent struts or without increasing the metal fraction of the stent. These special measures of present invention will enhance the coating substances to a stent. Further, the present invention will enhance the reservoir capacity of the stent for different forms of restenosis reducing proteins, chemicals or drugs, and will prolong the releasing time duration of the substances.

- An example of a stent design useful with the present invention is disclosed in US Patent No. 5,954,743, incorporated herein by reference.
- Figure-1 a two-dimensional view of the stent 10 is illustrated and is seen from the outer surface of the cut-open, two- dimensional view.
- Stent 10 includes expansion columns 12 and connector columns 14 in a continuous and alternating pattern to form a longitudinal dimension and a vertical dimension. The vertical and longitudinal dimensions determine the circumference and the length respectively of stent 10.
- Expansion columns 12 have expansion struts 16 in a vertical zigzag or corrugated pattern.
- One expansion column 12 is linked to an adjacent expansion column 12 by connector column 14 between two adjacent expansion 12 columns.
- Connector columns 14 have connector struts 18 that serve as linking arms between expansion struts 16 in two adjacent expansion columns 12.
- Stent 10 has a proximal end 20 and a truncated end 22 in the middle of stent 10.
- stent 10 is a tubular structure that includes patterned expansion struts 16 and connectors struts 18 continuously linked circumferentially and longitudinally with a predetermined length.
- the total surface areas of struts 16 and 18 are limited to a certain percent of the total cylindrical surface area of tubular stent 10, particularly when stent 10 is expanded in a vessel, with enlarged (by stent expansion) stent cells 24 that make up the remainder of the total stent surface area.
- the amount of a coating substance applied to and retained by stent 10 is determined by the total surface area of stent struts 16 and 18.
- Coating substance is preferably a restenosis inhibiting agent that is a drug, polymer and bio-engineered material and combinations thereof. It will be appreciated that other types of coating substances, well known to those skilled in the art, can be applied to stent 10 of the present invention. Because the total stent strut surface areas are limited in size, the amount of coating substance applied to stent 10 is limited to a small volume. When stent 10 is expanded in a vessel the relative surface area of struts 16 and 18 decreases in relation to the areas of stent cells 24.
- the total cylindrical surface area of stent 10 when it is implanted and expanded inside of a vessel is equal to the sum of the strut surface areas, which do not change, and stent cells 24 areas.
- the size of stent cells 24 areas changes when stent 10 is expanded.
- the present invention increases the amount of the coating substance capacity of stent 10 without increase the metal fraction of stent 10.
- the present invention increases the coating substance retaining capacity of stent 10 by forming cavities that can be micro holes 26 which are made, punched, drilled or burned into the expansion and connector struts 16.
- micro holes 26 have openings 28 on outer surface of struts 16 and 18.
- Micro holes 26 are made and arranged in such a way so that they can be evenly distributed in struts 16 and 18. In this embodiment, micro holes 26 are evenly distributed through out the entire body of stent 10.
- the number of micro holes 26 illustrated in Figure 1 is only by example.
- micro holes 26 created in stent 10 can vary by increasing or decreasing the number according to the necessity and requirements when such stents are fabricated for clinical use. Additionally, the pattern of creating micro holes 26 in stent struts 16 and 18 can be varied according to the clinical and protocol needs. Although micro holes 26 in Figure 1 are made in straight lines, it will be appreciated that micro holes 26 can be made in any varied pattern or shape. Micro-holes 26 can be made to form any suitable shape or pattern as necessary, if they meet the structural or engineering requirements of stent 10. Micro holes 26 can be made in single line or in multiple lines in struts 16 and 18 and arranged in any pattern.
- width 30 of expansion strut 16 is shown as being larger than width 32 of connector strut 18. It will be appreciated that the relative widths can change and that width 32 can be greater than width 30.
- micro holes 26 can be based on the physical dimensions of struts 16 and 18. Micro holes 26 cannot have diameters or size as large as the width of struts 16 and 18. Micro holes 26 can have substantially smaller widths or diameters than widths 30 and 32 in order to maintain the structural integrity and radial strength of stent 10. In one embodiment, micro holes 26 have an effective size or diameter to provide an optimal retaining capacity of substances or drugs that are coated or deposited on stent 10. Similarly, the distance between micro holes 26 is selected to maintain the integrity of stent 10 while providing an optimal number of micro holes 26 to provide a sufficient coating substance retaining capacity. Micro holes 26 in struts 18 can be made smaller than micro holes 26 in expansion struts 16 and visa versa.
- Micro holes 26 and opening 28 can have more than one shape including but not limited to circular, square, oval, oblong, irregular, polygonal or a combination thereof, depending on the method used to create micro holes 26.
- the tools to create micro holes 26 can be mechanical, photochemical, laser, EDM and the like.
- the shape or configuration of micro holes 26 and openings 28 in stent struts 16 and 18 can be influenced by the size or diameter of the micro hole 26 made, as well as by other manufacturing factors such as a laser beam size, photochemical resolution or EDM cathode and the like.
- micro holes 26 penetrate the entire widths 30 and 32 of struts 16 and 18 at a perpendicular angle with opening 28 on both outer surface 34 and inner surface 36. Shaded areas 38 show the cross-sectional cut surface of struts 16 and 18. Micro holes 26 are created in a regular interval with the uninterrupted segment 28 between micro holes 26. Micro holes 26 communicate freely between outer surface 34 and inner surface 36. As can be seen, micro holes 26 increase the contact surface areas of stent struts 16 or 18 for the purpose of increasing the capacity of retaining the intended coating substance added to stent 10. The bore space of micro holes 26 also serve as micro reservoir chambers for the substance to be added, attached or coated to stent 10. When stent 10 is electropolished, the shape or dimension of micro holes 26 can be slightly changed.
- Figure 3(b) illustrates an embodiment where micro holes 36 are blind and extend from outer surface 34 but not do not continue to inner surface 36. Shaded areas 38 indicate cross-sectioned stent struts 16 and 18.
- micro holes 26 have cul de sac geometry's 40 that terminate in an interior of struts 16 and 18.
- Cul-de-sacs 40 serve as reservoirs for coating substances applied to stent 10.
- Cul-de-sacs 40 can be created at regular or irregular intervals with uninterrupted segments 42 between that are formed between micro holes 26.
- micro holes 26 are shown with their axes at a slant angle relative to stent struts 16 and 18.
- micro holes 26 extend from outer surface 34 to inner surface 36. Because micro holes 26 have a slant angle through in this embodiment, the length and reservoir capacity of the micro holes 26 is increased compared to the capacity of the Figure 3(a) micro holes 26.
- micro holes 26 have openings 28 on outer surface 34 and cul de sacs 40 on inner surface 36, all formed at a slant angle.
- Outer surface 34 has uninterrupted segments 42 between slant angled micro holes 26 and inner surface 36 is smooth without openings 28.
- cul-de-sac 40 provides a reservoir for a coating substance applied to stent 10. Because the bore space of micro holes is at a slant angle there is an increased reservoir capacity.
- the cavities formed in Figure 4 are micro slits, groves, and the like, collectively denoted as 40, which have widths 44 that are larger than openings 36.
- the micro slits 40 shown in Figure 4 provide a larger reservoir capacity for the coating substance.
- Micro slits 40 can be evenly or unevenly distributed in struts 16 and 18.
- the number of micro slits 40 illustrated in Figure 4 is only by way of example. Increasing or decreasing the number of micro slits 40 created in stent 10 may vary according to the clinical and pharmcodynamic necessity and requirements. Additionally, the pattern of creating micro slits 40 in struts 16 and 18 can vary according to the clinical and engineering needs.
- micro slits 40 illustrated in Figure 4 are in straight lines, micro slits 40 can be made in curvilinear, square-angles, slant angled and the like with or without radius of curvature.
- Micro slits 40 can be made in any suitable pattern or shape as required, if they meet the structural or engineering requirements of stent 10. Micro slits 40 can be made in single line or in multiple lines in struts 16 and 18 and arranged in any other pattern.
- the Figure 4 embodiment illustrates that micro holes 26 can also be included in the same stent 10.
- FIG. 5 The magnified view of stent 10 illustrated in Figure 5 shows struts 16 and 18 with micro slits 40 and openings 46 on outer surface 34 of stent 10.
- Width 34 of expansion strut 16 is larger than width 32 of strut 18 in this embodiment.
- widths 34 and 32 can be the same in size or even reversed.
- Width 44 of micro slit 40 is determined by the physical dimensions and limits of struts 16 and 18. Width 44 can not be made as large as widths 34 and 32. Width 44 is substantially smaller than width 34 in order to maintain the structural integrity and radial strength of stent 10.
- the length of micro slit 40 can be made as long as stent struts 16 and 18.
- the length of micro slit 40 can be shorter or longer than the width of struts 16 and 18.
- the uninterrupted distance 42 between micro slits 40 is selected so that the structural integrity of stent 10 is not compromised.
- micro slits 40 can be made in different sizes or dimensions in same or differing patterns.
- Micro slits 40 in struts 18 can be made smaller than, the same as or greater than micro- slits 40 formed in struts 16.
- micro slits 40 and opening 46 can be different than that illustrated in Figure 5.
- the geometry of micro slits 40 can be straight linear, curvilinear, angled, squared or any other shape, depending on the design of stent 10 and the method used to make micro slits 40 during the manufacturing process.
- the tools to create the micro slits 40 can be the same as those used for micro-holes 26. Different shapes, sizes and positions of micro slits 40 can be included in an individual stent 10.
- micro slits 40 can extend through struts 16 and 18 with openings 50 on both outer and inner surfaces 34 and 36. Micro slits 40 can be created in a regular interval with uninterrupted segment 42 between micro slits 40.
- micro slits 40 can communicate freely between outer surface 34 inner surface 36. Micro slits 40 increase coating substance contact surface areas of struts 16 and 18 for the purpose of increasing the reservoir capacity of intended coating substances.
- Figure 6(b) illustrates that blind micro slits 40 partially extend into struts 16 and 18 from outer surface 34.
- Blind micro slits 40 end in cul-de-sacs 48 which can be of any desired geometric configuration.
- Cul-de-sacs 48 create micro reservoirs 50 for coating substances and can be formed at regular or irregular intervals with uninterrupted segments 42 between blind micro slits 48.
- the reservoir capacity of blind micro slits 40 is greater than that of blind micro holes 26.
- micro slits 40 can also be made in slant angles.
