Self-expanding T-shaped stent-graft prosthesis for arterialization of the aorto-iliac arterial segment

摘要

FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to cardiovascular surgery, and can be used to treat patients with occlusive diseases of the terminal portion of aorta and iliac arteries. Self-expandable T-shaped stent-graft-prosthesis consists of the main body and the bifurcation part of the aorto-bifurcation prosthesis. Main body is made of dacron or lavsan prosthesis reinforced from the inside by a self-opening metal stent with a closed cell type. Bifurcation part of the aorto-bifurcation prosthesis is sewn with a continuous locking stitch with a monofilament non-absorbable material into the formed oval hole on the side wall of the main body. Main body is compressed-packed into a peel-away introducer, at the same time being a delivery system, and has the possibility of disclosure after positioning in the necessary part of the aorta while removing the delivery system due to its own forces of radial stability.EFFECT: invention makes it possible to perform a seamless aortic prosthetic anastomosis, avoid prolonged aortic clamping, minimize the time of the training process, is fully compatible with traditional laparotomy access, mini-laparotomy and, directly, laparoscopic access.1 cl, 14 dwg
