Abstract
A mechanical heart valve prosthesis has a generally rectangular orifice and two leaflets that move between a closed position nearly perpendicular to blood flow and an open position nearly parallel to blood flow. Due to the uniform dimension of a rectangle, the leaflets are hinged at the periphery of the orifice, and present a single large central flow region to the blood when opened. The base provides several means of constraining the leaflet rotation during opening and closing.

A heart valve prosthesis comprising:
- a. a base including a blood passageway that is substantially rectangular,
- b. a means for regulating flow comprising at least one leaflet, and
- c. a means for maintaining said regulating means,
- whereby said heart valve prosthesis permits said regulating means to open, enabling substantially central forward blood flow.
A heart valve prosthesis comprising:
- a. a base including a blood passageway that is substantially rectangular,
- b. a means for regulating flow comprising at least one leaflet, and
- c. a means for maintaining said regulating means, wherein said maintaining means comprises one or more sockets,
- whereby said heart valve prosthesis permits said regulating means to open, enabling substantially central forward blood flow.
