Patent ID: 7425219

Claim:
A system for endoluminal grafting of a native, main anatomic conduit, in a region where at least one branch anatomic conduit extends from the main anatomic conduit, comprising: an endoaortic graft including a first pliable tube having a lumen extending longitudinally therefrom, at least one branch opening formed in the first pliable tube, a flexible magnetic ring positioned around the at least one branch opening of the first pliable tube, and endoaortic graft anchoring means for holding the first pliable tube in substantially fixed place within the main anatomic conduit with the branch opening is in alignment with the branch anatomic conduit, the first pliable tube being made of a biocompatible material; and a branch graft including a second pliable tube having a proximal end, a mid-portion, a distal end, a lumen extending therethrough, connector means for connecting the proximal end with the branch opening of the first pliable tube to allow the fluid that flows through the lumen of the endoaortic graft to pass through the branch opening into the lumen of the branch graft, and branch graft anchoring means at the distal end for holding at least the distal end of the branch graft in contact with the surrounding wall of the branch anatomic conduit, the second pliable tube being made of a biocompatible material, wherein the connector means comprises a hollow elastic toroid filled with a ferro-fluid having sufficient magnetic properties to be attracted to the flexible magnetic ring yet still be easily movable relative thereto.
