System and method for endoluminal grafting of bifurcated or branched vessels
First Claim
1. A system for endoluminal grafting of an anatomical conduit having at least one branch anatomical conduit emanating therefrom, said system comprising:
- a) a tubular primary graft for deployment in the anatomical conduit;
i) said primary graft having first and second ends and a lumen extending longitudinally therethrough;
ii) a branch graft opening formed at a first location in the primary graft;
iii) a first connector member formed adjacent the branch graft opening; and
,iii) a primary graft anchoring component operative to hold at least the first and second ends of the primary graft in substantially abutting contact with the anatomical conduit at locations on either side of said branch anatomical conduit, said primary graft anchoring component being thereby operative to hold the primary graft in a substantially fixed position within the lumen of the anatomical conduit such that its branch graft opening is substantially aligned with said branch anatomical conduit; and
,b) a tubular branch graft for deployment into the branch anatomical conduit;
i) said branch graft having a proximal end, a distal end, and a lumen extending longitudinally therethrough, and said branch graft being advanceable distal-end-first through the branch graft opening and into the branch anatomical conduit;
ii) a second connector member being associated with the proximal end of the branch graft, said second connector member being configured to automatically frictionally engage said first connector as the proximal end of the branch graft is brought into approximation with the branch craft opening of the primary graft, said automatic frictional engagement of the second connector to the first connector being operative to form a connection between the proximal end of the branch graft and the primary graft.

Abstract
A system and method for endoluminal grafting of a main anatomical conduit (e.g., the aorta) and various branch conduits (e.g., side branch vessels such as the carotid, innominate, subclavian, intercostal, superior mesenteric, celiac, or renal arteries-or furcations such as the iliac arteries) which emanate from the main anatomical conduit. The grafting system generally comprises i) a primary graft having at least one opening therein and ii) at least one branch graft which is passable through the opening of the primary graft and into the branch conduit(s) such that the proximal end of each branch graft is in substantially fluid-tight sealing contact with the primary graft. Also disclosed is a specific system and method for grafting a bifurcated anatomical conduit (e.g., the aorto-iliac bifurcation) though only a single access opening (puncture site or incision) and a new balloon-anchorable guidewire system which is useable in the performance of such grafting of bifurcated anatomical conduits and numerous other medical procedures.
