Patent ID: 7972374

Claim:
A modular endovascular graft system of conjoinable prostheses, the system comprising: a first graft prosthesis with a mating end comprising a mating surface and a second graft prosthesis comprising graft material with a mating end comprising a mating surface; a securing rod attached to the mating end of the first graft prosthesis, the securing rod comprising at least one spike jutting from the securing rod and oriented against a predetermined dislocation force; wherein the at least one spike is received by a first layer of graft material on the mating end of the second graft prosthesis upon conjoining the mating ends of the first and the second graft prosthesis; wherein the at least one spike protrudes through the first graft prosthesis and grabs the graft material of the mating end of the second graft prosthesis without penetrating through the graft material of second prosthesis; and wherein the mating surfaces of the first graft prosthesis and the second graft prosthesis form a material to material interface to provide a fluid tight seal at the interface when conjoined.
