Abstract: An anastomotic device and method for receiving the free ends of anatomic tubular structures to be anastomosed, the device having a pair of ring members for securement to the free end of each of the tubular members to be anastomosed and the ring members having annular connecting structure which mate with each other to connect the ring members. Novel securement structure is associated with the annular connecting structure to enable the securement of the ring members in a fixed relationship at a predetermined distance from each other. Structure is provided to connect each tubular member free end over a ring member so that the free ends are positioned contiguous to each other around the connecting structure to enable the ends to grow together in an atmosphere outside the flow path of the tubular members to be anastomosed and approximate the outer surface of the tubular member.
