Access port system for anastomosis

摘要

An access port system of the present invention provides a passageway through which instruments are inserted into a target vessel during performance of an anastomosis procedure. The access port system is secured to an exterior surface of the target vessel and assists in axial alignment, depth registration, and sealing when inserting instruments into the target vessel. The access port system provides the capability of placing punching instruments, anastomosis instruments, and other instruments in their correct positions relative to a target vessel and providing hemostasis while inserting instruments into and removing instruments from the target vessel.
