Anastomotic device

Claim 1

An anastomosis device for use in the surgical joining of the free ends of two tubular members to be anastomosed, said device comprising: a pair of identical ring members for securement to the free end of each of the tubular members to be anastomosed; at least one mating prong and one separate prong integral with and depending from each of said ring members, and prongs cooperatively mating with each other to form an annular coupling tube connecting said ring members; cooperatively connectable engaging pawls and locking slots formed in said separate and mating prongs enabling the securement of said ring members at first and second predetermined distances from each other whereby said tubular member free ends are ultimately positioned contiguous to each other proximate said ring members and said engaged separate and mating prongs; suture means extending around each tubular member free end pulling and holding said free end proximate said ring member and said engaged and separate mating prongs forming said annular coupling tube, and contiguous to the other tubular member free end whereby said engaging pawls engage said locking slots and secure said ring members at a first predetermined distance from each other to enable the positioning of said tubular member free ends proximate said ring members and the placement of said purse-string suture there around and said engaging pawls engage said locking slots and secure said ring members at a second predetermined distance from each other when said ring members are moved toward each other to position said tubular member free ends contiguous to each other without penetrating the tubular member free ends and enable said free ends to grow together and approximate the inner, middle and outer surfaces of the tubular member without necrosis.
