  • Support system for bioprosthetic valves with commisural posts with heart-shaped openings
    Patent number: 8585757
    Abstract: A novel support system for bioprosthetic cardiac valves with heart shape commissural posts (18) and intercommissural conjunctions with long openings with oval closures (8), allows the better function of the valve by diminishing the forces applied on the leaflets during the cardiac cycle.

  • Human cardiac valve placement with marine mammal ventricular outflow (aortic or pulmonary) valve
    Patent number: 6165216
    Abstract: The present invention provides a method of treating human cardiac valve dysfunction, by replacing the existing valve with a novel bioprosthesis of the present invention which comprises a marine mammal ventricular outflow (aortic or pulmonary) valve. The marine mammal ventricular outflow valve is treated by a fixative agent to sterilize, fix, increase the strength of the leaflets and lessen the antigenicity of the tissue valve. Following this step, the marine mammal ventricular outflow valve can either be stent-mounted or can be unstented. The stent-mounted marine mammal ventricular outflow valve can be used to replace a human aortic, mitral, or tricuspid valve, while the unstented marine mammal ventricular outflow valve can be used to replace a human aortic or pulmonary valve.
