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

1. An anchor for securing a graft to a vessel wall, comprising:

a body, having a proximal end, a distal end, and a longitudinal axis;

at least one proximal arm on the body for resisting distal movement of the anchor through tissue; and

at least one distal arm on the body for resisting proximal movement of the anchor through tissue;

wherein the proximal and distal arms are moveable between a first position in which the cross section of the anchor is minimized and a second position in which the arms are deployed.

2. An anchor as in claim 1, wherein the arms are biased in the direction of the second position.

3. An anchor as in claim 1, wherein the arms are moveable into the second position in response to axial shortening of the anchor.

4. An anchor as in claim 1, wherein the arms and body are integrally formed from a tube.

5. An anchor as in claim 1, comprising from two proximal arms to about six proximal arms.

6. An anchor as in claim 1, comprising from two distal arms to about six distal arms.

7. An anchor as in claim 1, comprising a nickel titanium alloy.

8. An anchor as in claim 1, wherein the at least one proximal arm and the at least one distal arm are integral with the body.
