  • Method of making a cardiac valve
    Patent number: 7988900
    Abstract: There is provided an artificial cardiac or heart valve, more particularly a flexible leaflet heart valve used to replace natural aortic or pulmonary valves of the heart in which the leaflet geometry is defined by a parabolic function and a method of manufacturing said artificial cardiac valves. In addition, there is provided leaflets which have geometry defined by a parabolic function.

  • HEART VALVE PROSTHESIS AND METHOD OF MANUFACTURE
    Publication number: 20110049757
    Abstract: A cardiac valve prosthesis having a frame and two or more leaflets (preferably three) attached to the frame. The leaflets are attached to the frame between posts, with a free edge which can seal the leaflets together when the valve is closed under back pressure. The leaflets are created in a mathematically defined shape allowing good wash-out of the whole leaflet orifice, including the area close to the frame posts, thereby relieving the problem of thrombus deposition under clinical implant conditions.
