Prosthetic valves with mechanically coupled leaflets

PROSTHETIC VALVES WITH MECHANICALLY COUPLED LEAFLETS A prosthetic valve (100, 1010) defining an inflow direction into the valve and an outflow direction out of the valve in operation, the valve comprising: a plurality of leaflets (310, 1040) including a first leaflet (310a) and a second leaflet (31Ob), each leaflet having a leaflet attachment region (330, 1043) and a free edge (312, 1054) opposite a base; and a frame (200, 1020, 1600) including a commissure post (210, 1022) that includes, a first tine (214) including a first interior edge (224) and a first exterior edge (225) opposite the first interior edge, a second tine (215) including a second interior edge (226) and a second exterior edge (227) opposite the second interior edge, a spine (213) positioned between the first and second tines such that the interior edges of the first and second tines face the spine, a first slot (216) defined between the first tine and the spine, the leaflet attachment region of the first leaflet being coupled to the frame at the first slot, and a second slot (217) defined between the second tine and the spine, the leaflet attachment region of the second leaflet being coupled to the frame at the second slot, the first and second slots diverging from one another in the outflow direction.
