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.
Claims25
A method of securing tissue, comprising:
- delivering an introducer transluminally through a blood vessel to a location adjacent a first tissue portion;
- advancing said introducer through said first tissue portion and a second tissue portion, the introducer having a sharpened tip to penetrate the tissue portions, the introducer removably carrying an anchor at least partially through the tissue portions;
- and
- retracting the introducer from the tissue portions, leaving the anchor in position in the tissue portions;
- whereby the anchor secures the first and second tissue portions together by resisting proximal and distal migration of the anchor relative to the tissue portions.
2 more elements
A method of securing a first tissue portion to a second tissue portion comprising:
- providing a catheter having at least one anchor support moveable between an axial orientation and an inclined orientation, and an anchor carried by the at least one anchor support;
- advancing the catheter to a target site near the first tissue portion while the anchor supports are in the axial orientation;
- moving the anchor support from the axial orientation to the inclined orientation;
- and
- deploying at least one anchor from the anchor support into the first tissue portion and second tissue portion.
2 more elements
A method of securing a first tissue portion to a second tissue portion comprising:
- advancing a catheter to a position adjacent at least the first tissue portion;
- and
- deploying at least one tissue anchor from the catheter and into the first tissue portion and second tissue portion,
- wherein the at least one tissue anchor comprises a body having at least one proximal arm integrally formed with the body being moveable from a collapsed configuration in which the proximal arm is generally axially aligned with the body to an outwardly extending configuration in which the proximal arm is biased in a generally distal direction, the proximal arm engaging the first tissue portion;
- and
- wherein the body of the at least one tissue anchor has at least one distal arm integrally formed with the body being moveable from a collapsed configuration in which the distal arm is generally axially aligned with the body to an outwardly extending configuration in which the distal arm is biased in a generally proximal direction, the distal arm engaging the second tissue portion.
