Benefits of technology

Facilitates precise and efficient vascular anastomosis with maintained blood flow, reducing surgical time and complications such as emboli and bleeding, while allowing for connection of graft vessels to target vessels prior to incision.

Problems solved by technology

The suturing process is a time consuming and difficult procedure requiring a high level of surgical skill.
This suturing requires a high degree of precision and is quite time consuming.
The use of a side clamp or similar device can cause emboli to detach from the wall of the aorta and enter the bloodstream, which is undesirable.

Embodiment Construction

[0101] As shown in FIG. 1, one embodiment of an anvil 10 includes a handle 12 and an anvil arm 14 extending from the handle 12. The anvil arm 14 may be oriented substantially perpendicular to the handle 12, or oriented at a different angle. The anvil arm 14 may be provided with one or more staple bending features 16 on opposite sides of the anvil arm 14. In the anvil 10 shown in FIG. 1, the staple bending features 16 each include a plurality of recesses 20 which receive the ends of staples 22 and cause the staple ends to bend over. At least one of the staple bending features 16 may be configured differently or omitted, if desired. The staples 22 may be connected to a staple holding strip 24. The staples 22 are U-shaped and are arranged in a spaced apart parallel configuration such that the staples 22 all lie in a single plane. Alternately, the staples 22 may be shaped differently, and / or lie in one or more different planes. An exemplary anvil arm 14 has a height and a width of about...

Abstract

A method for connecting a graft vessel to a target vessel, each vessel having a wall surrounding a lumen, may include providing a connector holder, associating an end of the graft vessel with the connector holder, positioning the connector holder outside of the lumen of the target vessel, outside the lumen of the graft vessel, and in proximity to the outer surface of the wall of the target vessel, and actuating the connector holder to secure the end of the graft vessel to the side of the target vessel.

Description

[0001] This application is a continuation of U.S. patent application Ser. No. 10 / 392,336, which in turn is a continuation-in-part of U.S. patent application Ser. No. 10 / 151,441, which in turn is a continuation-in-part of U.S. Pat. No. 6,391,038. Additionally, this application claims priority to U.S. Provisional Patent Application Ser. No. 60 / 399,880, filed on Jul. 31, 2002.FIELD OF THE INVENTION [0002] The invention relates to an apparatus and method for performing anastomosis. BACKGROUND [0003] Anastomosis is a procedure by which two hollow tissue structures are joined together. More particularly, vascular anastomosis is a procedure by which two blood vessels within a patient are surgically joined together. Vascular anastomosis is performed during treatment of a variety of conditions including coronary artery disease, diseases of the great and peripheral vessels, organ transplantation, and trauma. In coronary artery disease (CAD) an occlusion or stenosis in a coronary artery interf...
