Abstract

An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system. Furthermore, the graft may be configured with a plurality of synthetic fiber tufts secured to the outer surface of the tubular body to facilitate sealing the graft within the vessel. The graft may also include a plurality of crimps formed in the tubular body of the graft.

Claims

1. A graft for repairing a vessel having a wall, comprising:

a graft body;

a generally sinusoidal wire frame affixed to the graft, the wire frame having a plurality of alternatively oriented apices; and

a plurality of lumen piercing members associated with the wire frame, the plurality of lumen piercing members having a length sufficient to pierce but not puncture through a wall of a vessel.

2. The graft of claim 1, wherein the plurality of lumen piercing members are affixed to the wire frame.

3. The graft of claim 1, wherein the plurality of lumen piercing members are embodied in V-shaped anchoring members.

4. The graft of claim 3, the V-shaped anchoring members further comprising an apex and ends bent radially outward forming hooks.

5. The graft of claim 3, the V-shaped anchoring members further comprising an apex with a helical configuration.

6. The graft of claim 3, wherein the v-shaped anchoring members are configured between at least one of the plurality of alternatively oriented apices of the generally sinusoidal wire frame.

7. The graft of claim 1, the generally sinusoidal frame further comprising apices having a helical configuration.

8. The graft of claim 1, wherein the graft body has a tubular configuration.

9. The graft of claim 1, the graft body further comprising a plurality of crimps formed circumferentially around the graft body.

10. The graft of claim 1, wherein the generally sinusoidal wire frame is configured to exert an outwardly directed bias.

11. The graft of claim 1, wherein the generally sinusoidal wire frame is self-expanding.
