A tool is described for deploying a sutureless vascular anastomosis connection, including a body, a sheath configured to house a connector, the connector being configured to couple a graft vessel to a main vessel, the sheath being removably coupled to a distal end of the body, a dial disposed on a proximal end of the body, a spring disposed within the body and coupled to the dial, a shaft extending from the distal end of the body into the sheath, the shaft having a shaft cannula, a plunger having a plunger head configured to be coupled with the spring at one end, the plunger coupled to the shaft at an opposite end, and a retractable needle coupled to the dial using a retraction mechanism, the retractable needle configured to fit within the shaft cannula, the retractable needle having a sharp end.

Deployment tool for sutureless vascular anastomosis connection

A system is described for performing vascular anastomosis without the use of sutures. The system includes a connector comprised of memory material and an incision seal. The connector has one end configured to securely engage a graft vessel and another end with wings and barbs. The wings are configured to securely engage an inner wall of a main vessel and the barbs are configured to lock with the incision seal. Once locked, the incision seal and the connector apply a clamping force that secures the graft vessel with the main vessel.

Sutureless vascular anastomosis connection

Techniques for sutureless vascular anastomosis are described, including an incision seal including a base configured to partially house an outer surface of a main vessel, the base being formed using a material that is configured to be penetrated by a barb disposed on a connector the main vessel being secured to the base when the base is at least partially pierced by the barb, an upper lumen configured to guide a graft vessel, and a housing opening configured to receive the graft vessel.

Techniques for sutureless vascular anastomosis are described, including a connector configured to provide fluid communication between a graft vessel and a main vessel, the connector having tines disposed circumferentially about an outer surface of the connector, a front wing coupled to the base, the front wing having a tine configured to engage an inner surface of the main vessel, and having a hinge coupling the front wing to the connector, and a rear wing coupled to the base, the rear wing having another tine configured to engage the inner surface of the main vessel, and having another hinge coupling the rear wing to the connector.

Techniques for sutureless vascular anastomosis are described, including a sutureless vascular anastomosis connector configured to couple a graft vessel to a main vessel, including a connector body configured to engage a main vessel when inserted into an opening in a wall of the main vessel, and a wing coupled to the connector body and formed using a memory material, the wing being configured to rotate about a transverse axis of the connector when a restraining force is removed from an exterior surface of the wing.

Techniques for sutureless vascular anastomosis are described, including a connector having a tip configured to be inserted into a graft vessel, a body having a tine configured to engage tissue associated with a graft vessel, and a base having a front wing, a rear wing, and a barb, each of the front wing, the rear wing, and the barb being formed integrally with the base using a memory material, wherein the front wing, the rear wing, and the barb deploy at one or more pre-determined angles when a restraining force is removed, the restraining force keeping the front wing, the rear wing, and the barb in substantially axial alignment with the body.
