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.
Staples, for example, can produce high mechanical loads which may result in tearing of the tissue around the staples.
As a result, staples cannot be placed too close to the incision cite in the target vessel.
Tissue bonding techniques, however, have met with limited success when used for performing vascular anastomosis.
Deficient apposition can cause leakage or the formation of weak bonds.
Proper tissue apposition during vascular anastomosis is particularly difficult to achieve due to the small size and the flexible, circular configuration of the blood vessels involved.

Embodiment Construction

[0047] The anastomosis system and method according to the present invention uses an anvil to control and support a tissue site during an anastomosis procedure wherein the graft and target vessel are attached together using a tissue bonding procedure such as adhesive bonding or tissue welding. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel to the coronary artery in a coronary artery bypass graft procedure. The anvil supports the wall of the coronary artery which is generally very thin, difficult to grasp, and susceptible to tearing. Although the present invention is particularly useful for performing anastomosis on blood vessels and for controlling very thin tissues such as the walls of the coronary arteries, the anvil may also be used for performing anastomosis on other vessels and for controlling other tissue sites.

[0048] As shown in FIG. 1A, an anvil 10 according to one aspect of the present invention includes a han...

Abstract

A method and system for performing anastomosis may use an anvil to control and support a tissue site during an anastomosis procedure involving tissue bonding techniques such as adhesive tissue bonding. Adhesive may be applied to mating surfaces of the graft and / or target vessels either before or after the vessels are brought into contact. Adhesive may be applied via an applicator associated with the anvil.

Description

[0001] This application is a divisional of U.S. patent application Ser. No. 10 / 136,007 filed on Apr. 30, 2002, which is a continuation-in-part of U.S. Pat. No. 6,398,797, filed on Nov. 29, 2000, which is a continuation of U.S. Pat. No. 6,391,038, filed on Jul. 28, 1999, which are hereby incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Related Art [0003] The invention relates to an anastomosis system and method for controlling a tissue site in an anastomosis procedure wherein blood vessels or other tubular or hollow organs are joined together by tissue bonding. [0004] 2. Background of the Related Art [0005] 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 disea...
