STENT-GRAFT WITH PROXIMAL AND DISTAL ATTACHMENT, DELIVERY CATHETER AND METHODS OF MAKING SAME

摘要

A metallic or pseudometallic covered stent in which the stent component and the cover component are each fabricated of biocompatible metallic or pseudometallic materials, in which the cover and the stent are joined by at least one juncture at each of a proximal and distal end of the stent and the cover. A method of joining the stent and the cover is also disclosed.

主权项

1. An implantable covered-stent, comprising:
a) a self-expanding stent having structural members and a length defined between a most proximal vertex and a most distal vertex of the structural members, at least one enlarged member projecting from at least one of the most proximal vertex or the most distal vertex, wherein each of the at least one enlarged members has a substantially planar surface and a width greater than the width of any structural member of the stent, and at least one fenestration is disposed between the most proximal vertex and the most distal vertex; and b) a metal cover member having a proximal end region, a distal end region, wall surfaces and a plurality of openings passing through the wall surfaces, wherein each of the plurality of openings has an open surface area less than an open surface area of the at least one fenestration;
wherein the metal cover at least partially occludes the at least one fenestration to form the implantable covered-stent.
