Aorto uni-iliac graft
First Claim
1. An intraluminal device for placement in a living body vessel comprising:
- a tubular body having a linear shape and an inner and an outer surface, the tubular body being radially expandable from a compressed state to an expanded state;
a plurality of undulating filaments extending circumferentially about the tubular body and forming a generally ring-shaped configuration; and
a plurality of specifically-configured engagement members disposed on the outer longitudinal surface of the tubular body and configured to frictionally engage an inner wall of a body vessel so as to inhibit longitudinal movement of the tubular body without piercing the vessel wall.

Abstract
A generally tubular intraluminal vascular graft having a linear shape that may be radially expanded from a compressed state to an expanded state within a body vessel is disclosed. The graft includes a plurality of stent portions which take the form of undulating filaments extending circumferentially along the tubular body and forming a generally ring-shaped configuration. The graft may further be equipped with a plurality of specifically-configured engagement members disposed on the outer surface of the graft which are configured to frictionally engage an inner wall of a vessel so as to inhibit longitudinal movement of the tubular body without piercing the vessel wall.

12. An endoluminal graft for placement in a living body vessel comprising:
-
an unbranched pliable, tubular graft body having a predetermined linear shape and circumference, an interior surface and an exterior surface; and
a plurality of generally circular wireforms circumferentially disposed along the interior surface of said graft body, said wireforms each being composed of at least two undulating wires, a first wireform being joined to a second wireform to form a joined pair of wire ends, each pair of wire ends extending through the graft body to the exterior surface thereof such that there is relative movement between the graft body and the wire ends, wherein the wire ends define a projection extension configured to frictionally engage a wall of the body vessel. - View Dependent Claims (13, 14)

15. An intraluminal conversion graft comprising:
-
a main trunk portion defining an interwoven tubular stent and graft element having at least a plurality of wireforms disposed therethrough;
engagement means for attaching a portion selected from the group consisting of a previously emplaced graft, a native vessel and an extension portion; and
an extension portion adapted to mate with the main trunk portion within a diseased segment of vessel. - View Dependent Claims (16, 17, 18)

19. A method of converting an emplaced graft, comprising the steps of:
-
providing an intraluminal graft body having a plurality of separate, spaced apart wireforms woven through the body, wherein the intraluminal graft has a main trunk portion and an extension portion;
using a catheter system to insert the main trunk portion into an aneurysmal section of an aorta within the emplaced graft;
expanding the main trunk portion to engage an interior wall of the emplaced graft and generate a flow path;
using a catheter system to insert the extension portion into an aneurysmal section of an aorta within the emplaced graft; and
extending said flow path by matingly engaging the extension with the main trunk portion. - View Dependent Claims (20)
