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 delivery instrument and a valve repair device. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to be attached to a native valve of a patient. The valve repair device includes a pair of paddles and a pair of gripping members. The paddles are movable between an open position and a closed position, and the paddles are configured to flex upon being attached to the native valve of a patient. The paddles and the gripping members are configured to attach to the native valve of the patient.

First claim

The invention claimed is:

1. A valve repair system for repairing a native valve of a patient during a non-open heart procedure, the valve repair system comprising:
a delivery device having at least one lumen;
a valve repair device configured to be delivered through the lumen of the delivery device, and configured to attach to a native valve of a patient, the valve repair device comprising:
a pair of paddles that are movable between an open position and a closed position;
wherein each paddle includes a main portion and first and second side portions that are integrally formed with the main portion and extend from the main portion and are configured to contour to the shape of the native valve;
wherein the pair of paddles are configured such that the first and second side portions flex away from the main portion upon being attached to the native valve of the patient; and
a pair of gripping members that are configured to attach to the native valve of the patient.

2. The valve repair system 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 1 , wherein each paddle of the pair of paddles comprise one or more flanges, and wherein the one or more flanges are configured to flex to place less stress on the native valve of the patient.

4. The valve repair system according to claim 1 , wherein the pair of paddles are configured to be in a compressed state when disposed in the lumen of the catheter, and wherein the pair of paddles are configured to expand upon being deployed from the catheter.

5. A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
a pair of paddles that are movable between an open position and a closed position;
wherein each paddle includes a main portion and first and second side portions that are integrally formed with the main portion and extend from the main portion and are configured to contour to the shape of the native valve;
wherein the pair of paddles are configured such that the first and second side portions flex away from the main portion to upon being attached to the native valve of the patient; and
a pair of gripping members;
wherein the paddles and the gripping members are configured to attach to the native valve.

6. The valve repair device according to claim 5 , 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.

7. The valve repair device according to claim 5 , wherein each paddle of the pair of paddles comprise one or more flanges, and wherein the one or more flanges are configured to flex to place less stress on the native valve of the patient.

8. The valve repair device according to claim 5 , wherein the pair of paddles are configured to be in a compressed state when disposed in the lumen of the catheter, and wherein the pair of paddles are configured to expand upon being deployed from the catheter.
