Abstract
The present invention provides a valve configured for insertion on the proximal and distal sides of a heart valve annulus to replace the heart valve of a patient. The valve comprises a first substantially annular portion adapted to be positioned on a proximal side of the annulus of a patient and a second substantially annular portion adapted to be positioned on a distal side of the annulus of a patient, wherein at least one of the first and second substantially annular portions is movable towards the other portion to a clamped position to clamp around the annulus. The second portion has a flow restricting portion extending therefrom and is movable between a first position to permit the flow of blood and a second position to restrict the flow of blood. In one embodiment, the valve has a suture joining the first and second portions to draw the first and second portions into closer proximity and a cinch member to secure the suture to maintain the first and second portions in the clamped position. In another embodiment, the first and second portions are connected by a first segment which biases the first and second portions toward the clamped position.

25. A valve configured for minimally invasive insertion on the proximal and distal sides of a heart valve annulus to replace the heart valve of a patient, the valve comprising:
-
a first substantially annular portion adapted to be positioned on a first side of the annulus of a patient; a second substantially annular portion adapted to be positioned on a second side of the annulus of a patient, at least one of the first and second substantially annular portions being movable towards the other portion to a clamped position to clamp around the annulus, the first and second substantially annular portions contained in an elongated reduced profile condition in a delivery position, the second substantially annular portion having a movable flow restricting portion extending therefrom, the flow restricting portion including a plurality of leaflets extending from the second portion in a direction away from the first portion, the leaflets extending circumferentially around the second portion and foldable inwardly towards a convergence region to restrict blood flow and movable outwardly to an open position to permit blood flow, the leaflets compressible to a reduced profile condition in a delivery position. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
