Stented vascular graft

摘要

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.

主权项

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.
