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.

1-19. (canceled)
An implantable device configured to be delivered into a body conduit of a patient, the implantable device comprising:
- a tubular vascular graft that has a length, an inside diameter, a first end, and a second end, the length including a first length portion and a second length portion that together make up the entire length of the implantable device;
- a stent coupled to the first length portion of the tubular vascular graft, the stent having a first end positioned toward the first end of the tubular vascular graft, a second end, and a length, the length of the stent being coextensive with the first length portion of the tubular vascular graft;
- and
- a sheath maintaining the stent at a compacted, delivery profile, the sheath being progressively releasable in a direction extending from the first end toward the second end of the stent.
An implantable prosthesis configured to be delivered into a body conduit of a patient, the implantable prosthesis comprising:
- a tubular graft including a first length portion and a second length portion that together make up the entire length of the implantable prosthesis;
- a stent coupled to the first length portion of the tubular graft, the stent being coextensive with the first length portion of the tubular vascular graft;
- and
- a splittable sheath maintaining the stent at a compacted, delivery profile, the sheath being progressively releasable.
An implantable prosthesis comprising:
- a tubular graft having a first end and a second end and including a first length portion and a second length portion;
- a stent coupled to the first length portion of the tubular graft, the stent being coextensive with the first length portion of the tubular vascular graft and the second length portion of the graft being unstented;
- and
- a sheath maintaining the stent at a compacted, delivery profile, the sheath being progressively releasable.
