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, each of said ring members having an inner and an outer surface and a plurality of slots and apertures therein; two mating prongs and two separate prongs joined to and depending from each of said ring members, said prongs cooperatively and alternatively mating with each other to form an annular coupling tube connecting said ring members, said coupling tube having a constant inner diameter; 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 over said ring members and around said engaged separate and mating prongs; a purse-string suture extending around each tubular member free end pulling and holding said free end over said ring member, around said engaged separate and mating prongs forming said annular coupling tube, and contiguous to the other tubular member free end, said separate prongs each having a single engaging pawl to a first location and two engaging pawls at a second location, and each of said mating prongs having a single locking slot whereby said single engaging pawl engages said locking slot and secures said ring members at a first predetermined distance from each other to enable the positioning of said tubular member free ends over said ring members and the placement of said purse-string suture therearound and said two engaging pawls engage said locking slot 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 and enable said free ends to grow together and approximate the inner, middle and outer surfaces of the tubular member without necrosis.
