Abstract
An anastomotic system including a plurality of needles loaded with sutures and a delivery tool. The sutures include a suture core and crimp or fastener member at a proximal end of the core. An anchoring sleeve is optionally provided at a distal end. The anchoring sleeve is configured to collapse and prevent retraction of the suture after insertion through the tissue wall. A method of deploying the needles using the delivery tool is also disclosed.
Claims30
A suture device, comprising:
- a suture core having a core inner lumen;
- a suture crimp positioned at a proximal end of the suture core, the crimp adapted to fasten a suture within the core inner lumen;
- and
- an anchoring sleeve positioned at a distal end of the suture core, the anchoring sleeve adapted to collapse and anchor the distal end of the suture core against a tissue wall.
An anastomotic system, comprising:
- a suture device including:
- a suture core having a core inner lumen;
- a suture crimp positioned at a proximal end of the suture core, the crimp adapted to fasten a suture within the core inner lumen;
- and
- an anchoring sleeve positioned at a distal end of the suture core, the suture core adapted to anchor the distal end of the suture core against a tissue wall;
- wherein the system further comprises:
- a tubular needle including a needle inner lumen for receiving the suture core;
- and
- a delivery tool for deploying the needles.
A method for delivering a suture to tissue, comprising:
- penetrating a tissue wall with a self-anchoring suture device in a first direction, the suture device comprising:
- a suture core;
- and
- an anchoring sleeve positioned at a distal end of the suture core, the suture core adapted to collapse in an axial direction;
- retracting the suture device in a second direction substantially opposite from the first direction to bring the anchoring sleeve into contact with the tissue wall;
- and
- further retracting the suture device such that the anchoring sleeve is compressed against the tissue wall.
A method for connecting an attachment ring to tissue using an anastomotic tool comprising a cup for receiving the attachment ring, comprising:
- positioning the cup over the tissue where the attachment ring is to be attached;
- applying suction to draw tissue into a region of the cup such that the tissue substantially conforms to the shape of the inner surface of the cup;
- and
- driving a needle through the attachment ring, tissue, and flaps of the attachment ring.
