Abstract
A wire stent for insertion and expansion into a passage-way comprises a plurality of curved sections that are formed into a generally circular configuration. Adjacent curved sections are joined by a bend or cusp, so that a series of alternating opposing loops are formed. The wire stent as formed has a cylindrical shape with a longitudinal opening through which a folded balloon catheter is inserted. The opposing loops are tightly contracted about the catheter so that the cylindrical shape has an overlap-ping region in which portions of adjacent loops longitudinally overlap. The loops are arranged so that when the balloon catheter is inflated, adjacent loops diverge circumferentially relative to each other, thereby decreasing the overlapping region while increasing the diameter of the cylindrical shape. As the diameter of the cylindrical shape increases, the wire stent contacts the surface of a passageway in which the stent is inserted.
Claims (2)
1. An apparatus for intraluminally reinforcing the lumen of a body passageway, comprising:
a tubular shaped stent having a first diameter which permits delivery of the tubular shaped stent into the lumen of the body passageway;
at least a portion of said tubular shaped stent having a second, expanded diameter, said portion being formable to said second diameter, without any change in length of said tubular shaped stent, upon application from the interior of said tubular shaped stent of an outwardly extending force, to expand said lumen and to retain said portion of said tubular shaped stent with said second, expanded diameter within said body passageway.
a tubular shaped stent having a first diameter which permits delivery of the tubular shaped stent into the lumen of the body passageway;
at least a portion of said tubular shaped stent having a second, expanded diameter, said portion being formable to said second diameter, without any change in length of said tubular shaped stent, upon application from the interior of said tubular shaped stent of an outwardly extending force, to expand said lumen and to retain said portion of said tubular shaped stent with said second, expanded diameter within said body passageway.
2. An apparatus for intraluminally reinforcing a body passageway, comprising:
an expandable intraluminal stent; and a catheter having an expandable, inflatable portion associated therewith and including means for mounting said ex-pandable intraluminal stent on said expandable, inflatable portion, whereby upon inflation of said expandable, inflatable portion of said catheter, said stent is forced outwardly into contact with the body passageway to remain therein, and the expansion of said stent is controlled by the expansion of said inflatable portion of said catheter.
an expandable intraluminal stent; and a catheter having an expandable, inflatable portion associated therewith and including means for mounting said ex-pandable intraluminal stent on said expandable, inflatable portion, whereby upon inflation of said expandable, inflatable portion of said catheter, said stent is forced outwardly into contact with the body passageway to remain therein, and the expansion of said stent is controlled by the expansion of said inflatable portion of said catheter.
