AORTIC PROTESIS FOR THE TREATMENT OF ABDOMINAL AORTIC ANEURISMS AND USE OF PROTESIS.

摘要

An aortic prosthesis for the treatment of abdominal aortic aneurysms, where the prosthesis comprises a hollow tubular material intended to be inserted intraluminally into the aorta, where the aorta has an upper proximal aortic neck and a distal aortic lower portion that forms an iliac bifurcation that It is divided into two iliac arteries, the prosthesis being characterized by comprising: a main portion of complacent prosthesis (13, 33, 59) that has a generally cylindrical shape with an upper end (18, 39, 60) intended to be firmly secured to the proximal aortic neck (5), and a lower end (20, 41, 42, 61, 75, 76) that moves freely and is constructed so as to remain completely in a position within the aneurysm and above the iliac bifurcation ( 3, 4), and at least a portion of the complacent iliac prosthesis (14, 34, 35) entirely made of fabric and having a generally elongated and cylindrical shape a with a lower end (24, 47, 53) intended to be firmly secured to one of the iliac arteries, and an upper end (23, 46, 52) to be securely connected in fluid flow communication to the lower end (20 , 41, 42, 61, 75, 76) of the main prosthesis portion, both iliac prosthesis portions also having at least one stent secured to the upper (23) and lower (24) ends thereof.
