Abstract
Disclosed herein are minimally invasive systems and methods for performing an edge to edge repair of a heart valve on a beating heart of a patient. One or more sutures are inserted into a plurality of leaflets of the heart valve while the heart is beating through a minimally invasive access. The sutures can be threaded through a suture crimp that is advanced to the leaflets. A movable gate on the suture crimp can be actuated to secure the sutures at an appropriate tension to maintain the leaflets in a coapted position.
Claims19
A method of crimping one or more sutures attached to a heart valve leaflet in a beating heart of a patient, comprising:
- minimally invasively inserting a suture into a heart valve leaflet in a beating heart of a patient such that a pair of free ends of the suture extend from the leaflet out of the body;
- threading the free ends of the suture through a loading aperture of a crimp body of a suture crimp;
- delivering the suture crimp along the suture to the leaflet with a delivery catheter;
- adjusting a tension on the suture to a desired tension;
- applying a force proximally on a suture clamping gate disposed within the crimp body to move the suture clamping gate proximally with respect to the crimp body from an open position in which the suture can slide freely through the loading aperture and a closed position in which locking tabs of the suture clamping gate interface with locking grooves in the crimp body to lock the suture clamping gate in the closed position to securely hold the suture between the suture clamping gate and the crimp body at the desired tension.
A method of repairing a heart valve in a beating heart of a patient, comprising:
- minimally invasively inserting a first suture into a first heart valve leaflet and a second suture into a second heart valve leaflet in a beating heart of a patient such that a pair of free ends of each of the first suture and the second suture extend from the leaflet out of the body;
- threading the free ends of the first suture and the second suture through a loading aperture of a crimp body of a suture crimp;
- delivering the suture crimp along the first suture and the second suture to the leaflet with a delivery catheter;
- adjusting a tension on the first suture and the second suture to a desired tension;
- actuating a suture clamping gate disposed with the crimp body to move the suture clamping gate with respect to the crimp body from an open position in which the first suture and the second suture can slide freely through the loading aperture and a closed position in which the first suture and the second suture are securely held between the suture clamping gate and the crimp body at the desired tension.
