Percutaneous aortic valve
First Claim
1. 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 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 second substantially annular portion having a flow restricting portion extending therefrom and movable between a first position to permit the flow of blood and a second position to restrict the flow of blood, a suture joining the first and second portions wherein tensioning of the suture draws the first and second portions to the clamped position and a cinch member positioned on the suture and connected to the second portion to retain the suture and the first and second portions in the clamped position.

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.

2. A replacement cardiac valve implantation system comprising:
-
a valve comprising a moving member, a first wire element having a first ring-like portion and a second separate wire element having a ring-like portion and a replacement valve extending therefrom, at least the first ring like portion being selectively and relatively movable towards and away from the second ring-like portion to selectively adjust the spacing between the first and second wire elements; a delivery member for introducing the wire elements into a patient'"'"'s body such that the first ring like portion is placed on a first side of the annulus and the second ring like portion with replacement valve is placed on the a second side of the annulus, the moving member moving the first and second ring like portions in closer proximity to secure the valve in a clamped position around the annulus. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
