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 surgical a valve repair device for repairing a native valve of a patient including a pair of paddles, and a pair of gripping members. The paddles are movable between an open position and a closed position, in which the paddles are moved to the open position by moving a pivot point of each paddle in an outward direction and pivoting each of the paddles about the pivot point of the paddle. The paddles and the gripping members are configured to attach to the native valve of the patient when the paddles are in the closed position.

Claims5

Dependent claims

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

a base assembly having:
a shaft;
and
a cam attached to the shaft and configured to move between a first position and a second position;
a pair of paddles attached to the base assembly, wherein the pair of paddles are configured to move between an open position and a closed position;
and
a pair of gripping members attached to the base assembly, wherein the gripping members are configured to attach to the native valve of the patient;
wherein movement of the cam from the first position to the second position causes a cam surface of the cam to slide against an engagement surface of the pair of paddles to move the pair of paddles from the closed position to the open position, and wherein movement of the cam from the second position to the first position allows the pair of paddles to move from the open position to the closed position.
