Systems and methods for applying a suture within a blood vesel lumen
First Claim
1. An endovascular suture assembly comprisinga tubular body defining a passage and having a distal region sized to be advanced within a blood vessel lumen occupied by a prosthesis, the distal region including a segment that is sized and configured to be moved into selective contact with the prosthesis in the blood vessel lumen, a suture applicator removably insertable through the passage, the suture applicator including a rotary head movable independent of and relative to the segment into selective association with the prosthesis in the blood vessel lumen, and a drive assembly for rotating the rotary head, a spiral suture carried by the rotary head, the spiral suture being sized and configured for advancement into tissue in the blood vessel lumen in response to rotation of the rotary head.

Abstract
Systems and methods apply a suture within a blood vessel lumen. The systems and methods advance within a blood vessel lumen a catheter tube having a distal region that carries a suture applicator. The systems and methods operate the suture applicator from a location external to the blood vessel lumen to apply a suture to an interior wall of a blood vessel lumen.
