Surgical clips and methods for tissue approximation
First Claim
1. A surgical clip for sealingly joining a graft vessel to a target vessel, the graft vessel having a graft vessel wall defining a graft lumen, the target vessel having a target vessel wall defining a target lumen, the surgical clip comprising:
- a clip body;
a needle portion extending from the clip body and having a distal end configured to penetrate the graft and target vessel walls and extend outside of the graft and target vessels, the clip body being configured to prevent passage of the clip body through the graft and target vessel walls; and
a retainer disposed outside of the graft and target vessels for retaining the graft and target vessel walls on the needle portion.

Abstract
Surgical clips, and methods of use thereof, are provided for tissue approximation and attachment, and more particularly, for sealingly joining a graft vessel to a target vessel. The graft vessel has a free end and a graft vessel wall defining a graft lumen. The target vessel has a target vessel wall defining a target lumen and has an opening in the target vessel wall. The anastomosis clip includes a clip body having a distal extremity with a distal end and a proximal extremity with a proximal end. The distal end is configured to penetrate through the graft vessel wall near the free end and through the target vessel wall near the opening such that both the distal and proximal ends of the clip body are outside the graft and target vessels. At least a portion of the clip body is shapable so as to compress the graft vessel wall against the target vessel wall with the target vessel lumen in communication with the graft vessel lumen.

17. An anastomosis device for sealingly joining a graft vessel to a target vessel, the graft vessel having a free end and a graft vessel wall defining a graft lumen, the target vessel having a target vessel wall with an opening therein and defining a target lumen, the anastomosis device comprising:
-
a flexible ring-shaped band defining a central opening in which the graft vessel may be received; and
a plurality of clips coupled to the band and positionable at spaced apart locations around the band, each clip having a first portion for engaging the graft vessel wall and a second portion for engaging the target vessel wall, the first and second portions being configured to retain the graft vessel wall in sealing engagement with the target vessel wall. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An anastomosis system for sealingly joining a graft vessel to a target vessel, the graft vessel having a free end and a graft vessel wall defining a graft lumen, the target vessel having a target vessel wall with an opening therein and defining a target lumen, the anastomosis system comprising:
-
at least one anastomosis clip including a clip body having a distal extremity with a distal end and a proximal extremity with a proximal end, the distal end being configured to penetrate through the graft and target vessel walls; and
a clip applier including a holding mechanism for releasably holding the anastomosis clip such that the distal end may be passed through the graft vessel wall near the free end and through the target vessel wall near the opening such that both the distal and proximal ends of the clip body are outside the graft and target vessels, and a shaping mechanism disposed outside the graft and target vessels for shaping at least a portion of the clip body so as to compress the graft wall against the target vessel wall with the target vessel lumen in communication with the graft vessel lumen. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A method of sealingly joining a graft vessel to a target vessel, the graft vessel having a free end and a graft vessel wall defining a graft lumen, the target vessel having a target vessel wall defining a target lumen and having an opening therein, the method comprising:
-
providing a plurality of anastomosis clips each including a clip body having a distal extremity with a distal end and a proximal extremity with a proximal end;
penetrating the graft vessel wall and the target vessel wall with the distal extremity of each anastomosis clip such that the distal and proximal ends are disposed outside of the graft and target vessels; and
shaping a portion of each clip body outside of the graft and target vessels so as to compress the graft vessel wall against the target vessel wall with the graft lumen in communication with the target lumen. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
