Abstract
Abstract Methods and apparatus for passing attachment apparatus (e.g., connector devices, staples, etc.) or connector material (e.g., suture thread, wire, cord, filament, monofilament, etc.) into or through the wall of a luminal anatomical structure (e.g., a blood vessel or other anatomical conduit) for the purpose of; i) closing the lumen of the anatomical structure, ii) forming an anastomotic junction between separate anatomical structures (or between approximated segments of the same anatomical structure), and/or iii) attaching an article (e.g., an endoluminal, extraluminal or transluminal graft) or other apparatus to the wall of the anatomical structure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
A device for fully or partially closing a blood vessel that has a wall, an outer surface and a lumen extending therethrough, said device comprising: a catheter that is advanceable into the lumen of said blood vessel; an elongate, resilient member having a distal end and at least one vessel engaging member formed thereon, said elongate member being biased to a coiled configuration; said elongate member being initially disposed in said catheter and subsequently deployable out of said catheter after the catheter has been advanced into the lumen of said blood vessel such that a) the elongate member passes distal-end-first from the lumen of the blood vessel outwardly through the wall of the blood vessel, b) the elongate member advances at least part of the way around the outer surface of the blood vessel without re-penetrating the wall of the blood vessel, and c) said at least one vessel engaging members engages the outer surface of the blood vessel and d) the bias of the elongate member causes it to assume a coiled configuration thereby causing the lumen of the blood vessel to become at least partially closed.
Claim 2
Independent Claim
188 words
A device for fully or partially closing a blood vessel that has a wall, an outer surface and a lumen extending therethrough, said device comprising: a catheter that is advanceable into the lumen of said blood vessel; an elongate, resilient member having a distal end and at least one vessel engaging member formed thereon, said elongate member being biased to a coiled configuration; said elongate member being initially disposed in said catheter and subsequently deployable out of said catheter after the catheter has been advanced into the lumen of said blood vessel such that a) the elongate member passes distal-end-first from the lumen of the blood vessel outwardly through the wall of the blood vessel, b) the elongate member advances at least part of the way around the outer surface of the blood vessel without re-penetrating the wall of the blood vessel, and c) said at least one vessel engaging members engages the outer surface of the blood vessel and d) the bias of the elongate member causes it to assume a coiled configuration thereby causing the lumen of the blood vessel to become at least partially closed.
Claim 3
Dependent Claim
13 words
The device of claim 1 wherein said vessel engaging member comprises a barb.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said tissue engaging member comprises a hook.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein said vessel engaging member comprises a projection.
Claim 6
Dependent Claim
14 words
The device of claim 1 wherein said vessel engaging member comprises a cross member.
Claim 7
Dependent Claim
63 words
The device of claim 1 further comprising: a penetration sleeve that has a distal end and a hollow bore extending th-therethrough, said penetration sleeve being initially advanceable from the catheter to penetrate outwardly through the wall of the blood vessel such that said elongate member is subsequently advanceable through the bore of the penetration sleeve about the outer surface of the blood vessel.
