Abstract
An aortic root prosthesis for being implanted into a patient during a valve sparing surgery as a replacement for a biological aortic root segment of an ascending aorta is disclosed. The aortic root prosthesis includes a hollow, annular tube having proximal and distal ends, and an inner and outer wall. The distal end is for being attached to the ascending aorta. A plurality of sinuses are circumferentially connected to the proximal end of the tube. Each of the sinuses is adapted for being attached to the aortic wall. Each of the sinuses also includes contouring means for imparting a convex contour to an outer wall of the sinus to thereby create a space between the open leaflet and its respective sinus to prevent impact between the leaflet of the valve and the inner wall of the sinus.
