HEARTH VALVE PROSTHESIS AND METHOD OF MANUFACTURE.

摘要

The present invention provides a cardiac valve prosthesis comprising a frame and two or more leaflets (preferably three) attached to the frame. The leaflets are attached to the frame between posts, whit 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.
