Stented vascular graft
First Claim
Patent Images
1. An implantable prosthesis having a length extending between opposing ends, comprising:
- a first length portion and a second length portion that together make up the entire length of the implantable prosthesis;
a first polymeric tubular element extending for the entire length of the prosthesis;
a first stent coaxially located around the first length portion of the first tubular element at one of said opposing ends;
a second polymeric tubular element coaxially located around the entire second length portion of the first tubular element wherein the combination of the second polymer tubular element and the second length portion of the first tubular element does not include a stent;
wherein the length of the second length portion is greater than the length of the first length portion, wherein said first tubular element provides an uninterrupted luminal surface extending for the length of the implantable endoprosthesis and wherein the second length portion is adapted to be sutured to an opening into a body conduit.

Abstract
A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.

- 20. An implantable prosthesis having a length extending between opposing ends, said implantable endoprosthesis comprising a polymeric tubular element extending for the entire length of the implantable endoprosthesis between the opposing ends of the prosthesis, said length of the implantable prosthesis consisting of first and second length portions each having a length, a wall thickness and an outer surface, and having a stent having a length and a wall thickness wherein the length of said stent is located coaxially about the outer surface of said first length portion of the polymeric tubular element, wherein said second length portion does not include a stent and wherein the wall thickness of said second length portion is at least about 20% greater than the wall thickness of said first length portion exclusive of the wall thickness of the stent, and wherein the length of the second length portion is greater than the length of the first length portion.
