Stent graft delivery system and methods of use
First Claim
1. A method of implanting a graft in a hollow-body organ or vessel, the method comprising steps of:
- providing a graft, an introducer catheter and a graft delivery component having a plurality of fingers, each of the fingers including a retention wire that releasably engages the graft, the fingers and the graft retained in a contracted state by the introducer catheter;
inserting the graft delivery component and introducer catheter transluminally to deliver the graft to a desired position in the hollow-body organ or vessel; and
retracting the introducer catheter to allow the fingers to resiliently deploy to an expanded state in which the graft is held in apposition to an interior wall of the hollow-body vessel or organ.

Abstract
A stent-graft delivery system and methods for use are provided for use in treating aneurysms occurring in single and bifurcated lumen hollow-body organs or vessels and for treating arterio-venous fistulas. A graft delivery component provides a clinician with complete control over the location of a graft at any time prior to implantation of stents, even when the graft is deployed from its introducer catheter. The graft delivery component includes a plurality of radially expandable fingers that releasably engage the graft, while the stent delivery component includes a small diameter introducer catheter and permits a wide range of conventional stent designs to be used to permanently fix the graft in position.

12. A graft delivery system for implanting a tubular graft in a hollow-body organ or vessel comprising:
-
a support tube having a circumference; a plurality of resilient fingers disposed about the circumference of the support tube, each of the resilient fingers having a tip, the resilient fingers movable between a compressed state in which the resilient fingers are compressively stressed so that the tips are disposed adjacent to the support tube and a deployed state in which the resilient fingers are in an unstressed state and the tips are deployed radially outward from support tube, each of the resilient fingers including retention means for releasably engaging a tubular graft; and an introducer catheter having a passageway, the introducer catheter being movable from a first position in which the plurality of resilient fingers are disposed within the passageway so that the introducer catheter compresses the resilient fingers to the compressed state and a second position in which the introducer catheter is retracted so that the plurality of resilient fingers are in the deployed state. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A stent-graft delivery system comprising:
a graft delivery component including; a plurality of resilient fingers, each of the resilient fingers having a tip, the resilient fingers movable between a compressed state in which the resilient fingers are compressively stressed so that the tips are disposed adjacent one another and a deployed state in which the resilient fingers are in an unstressed state and the tips are deployed radially outward from one another;
each of the resilient fingers including retention means for releasably engaging a tubular graft; andan introducer catheter movable from a first position in which the plurality of resilient fingers are retained in the compressed state and a second position in which the introducer catheter is retracted so that the plurality of resilient fingers are in the deployed state; and a stent delivery component, the stent delivery component carrying a stent for affixing the graft to a wall of a hollow-body organ or vessel. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
