Method and system of attaching vessels to grafts
First Claim
Patent Images
1. A graft coupling system comprising:
- a first stent for insertion in a transected vessel receiving a graft, said stent providing a rigid conduit for blood flow through said vessel and sized to allow a graft to be advanced to overlap at least part of a stented-area of said vessel; and
a second stent for surrounding at least a part of said area of overlap between said graft and said stented area, said second stent configured to apply sealing pressure to said graft in a part of said area of overlap, whereby said first and second stents sandwich said graft to provide a fluid tight seal between said vessel and said graft.

Abstract
A suture-less graft coupling system for anastamosis and bypass procedures comprising a first stent for insertion into a radially transected vessel being treated, a graft member overlapping the stented area of the transected vessel, and a second stent overlapping the graft and vessel in an area of the first stent wherein sealing pressure from the second stent can be applied to seal the vessel and graft in a leak-free arrangement.

13. A method of attaching a vessel to a graft at a target site comprising:
-
clamping the vessel up-stream from the target site; circumferentially transecting the vessel in an area of the target site; inserting a first stent into the transected vessel, wherein the stent radius approximates the radius of the vessel after deployment of said stent; overlapping the graft vessel with at least a portion of the transected vessel in the area of the first stent; and placing a second stent around at least a portion of the area of overlap of the vessel and the graft, wherein said second stent is configured to provide a sealing force to the portion of the area of overlap. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
