Abstract

A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are movable between an open position and a closed position. The paddles and the gripping members are configured to attach to the native valve of the patient. The paddles are biased to the closed position, latched to the gripping members in the closed position, maintained in the closed position by a threaded connection, or otherwise maintained in the closed position.

Claims

1. A valve repair device for repairing a native valve of a patient, the valve repair device comprising:

a pair of paddles that each comprise a latch member, wherein the paddles are movable between an open position and a closed position;

a pair of gripping members, wherein the paddles and the gripping members are configured to attach to the native valve of the patient;

wherein, when the paddles are in the closed position, the latch member of each of the paddles attaches each of the paddles to a corresponding gripping member of the pair of gripping members.

2. The valve repair device according to claim 1, further comprising a base assembly that comprises:

a shaft; and

a coupler movably attached to the shaft such that the coupler can be moved along the shaft;

wherein the pair of paddles are pivotally attached to the coupler;

wherein movement of the coupler in a first direction along the shaft causes the pair of paddles to move to the closed position, and movement of the coupler in a second direction causes the pair of paddles to move to the open position.

3. The valve repair system according to claim 2, further comprising a lock movable between a locked condition and an unlocked condition, wherein the lock is configured to lock the coupler in a stationary position on the shaft when the lock is in the locked condition.

4. The valve repair device according to claim 1, further comprising a spacer element configured to close a gap in the native valve of the patient when the valve repair device is attached to the native valve.

5. The valve repair device according to claim 1, wherein the gripping members are connected to each other by a biasing member that is configured to maintain the gripping members in a desired position.
