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, comprising:(a) a hollow, annular tube having proximal and distal ends, and an inner and outer wall, said distal end adapted for being attached to the ascending aorta; and (b) a plurality of sinuses circumferentially connected to the proximal end of said tube, each of said sinuses adapted for being attached to an aortic wall and including: (i) contouring means for imparting a convex contour to an outer wall of the sinus to thereby create a space between an open leaflet of an aortic valve and the respective sinus to prevent impact between the open leaflet and an inner wall of the sinus; and (ii) a plurality of Z folds formed in and extending along the vertical axis of the sinus parallel to the longitudinal axis of the tube for allowing the sinus to be stretched laterally.
