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.

Heart valve prosthesis and method of manufacture

A method and system for use in the course of extracorporeal blood flow, e.g., cardiopulmonary bypass, dialysis, and angioplasty procedures, in order to reduce or minimize inflammation, excessive bleeding, and other undesirable side effects. The system can include one or more automated blood parameter sensor modules and one or more blood parameter regulating modules. The system is particularly well suited to monitor and/or regulate blood parameters that include blood analytes (e.g., biomolecules, drugs or metabolites) as well as blood functions (e.g., clotting time, fibrinolytic activity, immune response). The system is particularly well suited for use in the management of clotting (e.g., heparing/protamine) and bleeding (e.g., aprotinin).
