Abstract

An anastomosis system for connecting a graft vessel to a target vessel includes an elongated anvil arm for insertion into the target vessel. The anvil arm includes a contact surface that contacts the inner surface of the wall of the target vessel. The anvil arm includes a channel through which a cutting element translates, and a opening that extends between the channel and the contact surface of the anvil arm. The cutting element is translated along the channel, and is controlled to extend through the opening and make an incision in the wall of the target vessel at a selected location. The incision is made at a location spaced apart from the penetration site at which the anvil arm is inserted into the target vessel, resulting in a tissue bridge between the incision and the penetration site.
