Abstract
Abstract Disclosed is an anastomosis catheter, for achieving a tissue to tissue or synthetic graft to tissue attachment. The catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may be used to achieve end to end or end to side anastomoses. Methods are also disclosed.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
79 words
An anastomosis catheter, comprising: an elongate, flexible body, having a proximal end and a distal end; at least one tissue anchor support on the body, movable between an axial orientation and an inclined orientation; and an anchor movably carried by the anchor support; wherein the anchor comprises a body having at least one proximal engagement surface for resisting distal travel of the body through tissue and a distal engagement surface for resisting proximal travel of the body through tissue.
Claim 2
Dependent Claim
79 words
An anastomosis catheter, comprising: an elongate, flexible body, having a proximal end and a distal end; at least one tissue anchor support on the body, movable between an axial orientation and an inclined orientation; and an anchor movably carried by the anchor support; wherein the anchor comprises a body having at least one proximal engagement surface for resisting distal travel of the body through tissue and a distal engagement surface for resisting proximal travel of the body through tissue.
Claim 3
Dependent Claim
16 words
An anastomosis catheter as in claim 1 , wherein the tissue anchor support comprises a tube.
