Abstract

An improved prosthesis for use in heart surgery for replacement of the aortic valve and the ascending aorta. It comprises a flexible tubular section 1 at one end of which 1c there is provided a ring with a valve 2, 2a for controlling blood flow at the level of the cardiac aortic annulus. Tubular section 1 has a bulb-shaped portion 1b lying between a cylindrical tubular portion 1a and valve 2. In the vicinity of the valve ring 2, 2a there is a seal comprising a first annular strip 3 adhering to tubular section 1c and a second annular strip 4 which is subdivided into three portions 4a and can be sewn onto first annular strip 3 with the patient's aortic annulus in between. The bulb shape and the structure of the seal make it possible to make the coronary anastomosis and the proximal anastomosis avoiding hazardous complications due to haemorrhage and the formation of pseudoaneurism and/or laceration of the sutures of the coronary anastomosis, complications which are often lethal. <IMAGE>
