A system and method of use for effecting the bypass or other anastomosis of a portion of a native blood vessel, duct, lumen or other tubular organ within the body of a living being. The system includes a connector assembly and a deployment instrument for carrying the device to the desired position within the vessel, duct, lumen or tubular organ. The system includes a piercer-dilator instrument to form an opening in the wall of the vessel, duct, lumen or tubular organ into which the connector assembly is deployed by the deployment instrument. The connector assembly is at least partially formed of a resorbable material and includes movable members for securing it to the tissue of the vessel, duct, lumen or tubular organ contiguous with the opening. Other components may be included in the device for expediting the anastomosis procedure, with or without the use of sutures. Moreover, the system can be used to bypass of at least two coronary arteries by a common connection with the aorta utilizing at least two bypass grafts, a single upstream anastomosis connector, a pair of downstream anastomosis connectors, and a common bifurcated midstream anastomosis connector, for securement between the aorta and the coronary arteries.
