DEVELOPMENT OF A METALLIC CONNECTING RING PROSTHESIS OF VASCULAR GRAFTS

Abstract

A new Titanium thin wall tube with two external fixation ring inserted between Dacron grafts to connect them was developed to help simplifying the operative procedure of thoraco - abdominal aortic reconstruction.
Physical stress test of three kinds revealed its tolerance as a vascular prosthetic implant. Especially, intraluminal pulsatile flow stress test of 260×10⁴ times utilizing a mock circulation circuit showed no obvious Dacron graft damage in the ring-graft interface.
