ABSTRACT:
An improved check valve which is particularly adapted for surgical implantation in the heart as a substitute for a natural heart valve. In one embodiment, the prosthetic valve (10) comprises a circular base (40) on which a pair of semiconical leaflets (42) are supported for pivotal movement between open and closed positions by T-shaped arms (60) and pin and slot connections. In a second embodiment (80), the semiconical leaflets (42') are supported and constrained for pivotal movement between open and closed positions by C-shaped arms (82) engaging apertures (84) and notches (86) on the leaflets. In the preferred construction, at least one of the leaflets (42, 42') can also translate for ease of operation.
