Native valve repair devices and procedures
First Claim
1. 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; and
a pair of gripping members that each have a barbed portion for securing the gripping member to the native valve of the patient;
wherein each gripping member of the pair of gripping members is slidably attached to a corresponding paddle of the pair of paddles;
wherein each gripping member is moved in a first direction along the paddle before the barbed portion of the gripping member pierces the native valve of the patient; and
wherein each gripping member is moved in a direction along the paddle substantially opposite the first direction after the barbed portion pierces the native valve of the patient such that the gripping members create a tensioning force on the native valve of the patient.

Abstract
A system for implanting a repair device onto a native valve of a natural heart to repairing 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. Each of the gripping members has a barbed portion for securing the gripping members to the native valve of a patient. Each gripping member is slidably attached to a corresponding paddle. Each gripping member can be moved in a first direction along the paddle before the barbed portion of the gripping member pierces the native valve of the patient. Each gripping member can be moved in a direction substantially opposite the first direction after the barbed portion pierces the native valve of the patient such that the gripping members create a tensioning force on the native valve of the patient.

5. A method for repairing a native valve of a patient, the method comprising:
-
moving a gripping member from a first position to a second position along a paddle; positioning the paddle such that valve tissue of a native valve of a patient is disposed between the gripping member and the paddle; closing the gripping member such that a barbed portion of the gripping member pierces the valve tissue; and moving the gripping member back along the paddle from the second position to the first position after the barbed portion of the at least one gripping member pierces the valve tissue. - View Dependent Claims (6, 7)

10. 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; and a pair of gripping members that each have a barbed portion for securing the gripping member to the native valve of the patient; wherein each gripping member of the pair of gripping members is movably attached to a corresponding paddle of the pair of paddles; wherein each gripping member is configured to move in a first direction relative to the paddle before the barbed portion of the gripping member pierces tissue of the native valve of the patient; and wherein each gripping member is configured to move in a different second direction relative to the paddle after the barbed portion pierces the tissue of the native valve of the patient such that the gripping members impart a tensioning force on the tissue of the native valve of the patient. - View Dependent Claims (11, 12, 13, 14, 15)

16. A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
-
a first paddle and a second paddle that are each movable between an open position and a closed position; and a first gripping member having a first barbed portion and a second gripping member having a second barbed portion; wherein the first gripping member is movably attached to the first paddle and the second gripping member is movably attached to the second paddle; wherein the first gripping member is configured to move in a first direction relative to the paddle before the first barbed portion of the first gripping member pierces tissue of the native valve of the patient and move in a different second direction relative to the paddle after the barbed portion pierces the tissue of the native valve of the patient such that the first gripping member imparts a tensioning force on the tissue of the native valve of the patient. - View Dependent Claims (17, 18, 19, 20)
