Mitral valve treatment techniques
First Claim
1. A method for treating a heart valve of a patient, the method comprising:
- inserting into a heart of the patient and in contact with a valve surface of the heart valve, an implant including an elongate element and a locking mechanism coupled to the elongate element, the locking mechanism having a resting position that provides a locked state in which movement of the elongate element with respect to the locking mechanism is prevented;
subsequently to the inserting, performing annuloplasty on the heart valve of the patient by increasing tension of the elongate element by maintaining application of a force to the locking mechanism using a tool, and thereby maintaining the locking mechanism in an unlocked state during the increasing of the tension of the elongate element; and
subsequently to the performing of the annuloplasty on the heart valve and subsequently to coupling proximal and distal ends of the implant to tissue at the heart valve, transitioning the locking mechanism to the resting position by decoupling the tool from the locking mechanism.

Abstract
A method for treating a heart valve of a patient includes inserting into a heart and in contact with a valve surface, an implant including an elongate element and a locking mechanism coupled to the elongate element. The locking mechanism has a resting position that provides a locked state preventing movement of the elongate element with respect to the locking mechanism. The heart valve is treated by facilitating movement of the elongate element with respect to the locking mechanism by maintaining application of a force to the locking mechanism using a tool, and thereby maintaining the locking mechanism in an unlocked state during the facilitating of the movement of the elongate element with respect to the locking mechanism. Subsequently, the locking mechanism is transitioned to the resting position by decoupling the tool from the locking mechanism.

14. A method for treating a heart valve of a patient, the method comprising:
-
inserting into a heart of the patient and in contact with a valve surface of the heart valve an implant including an elongate element and only one locking mechanism coupled to the elongate element, the locking mechanism having a resting position that provides a locked state in which movement of the elongate element with respect to the locking mechanism is prevented; and while a tool is engaged with the locking mechanism, performing annuloplasty on the heart valve of the patient by, using the tool; applying a force to the locking mechanism and thereby transitioning the locking mechanism out of the resting position into an unlocked state; and increasing a tension of the elongate element; and subsequently to the performing of the annuloplasty on the heart valve, transitioning the locking mechanism to the resting position by decoupling the tool from the locking mechanism. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
