Method and apparatus for transapical procedures on a mitral valve
First Claim
1. A method, comprising:
- disposing on an atrial side of a first leaflet of a mitral valve a first implant, the first implant including a first loop portion, a first suture portion extending from the first loop portion proximally through the first leaflet to the ventricular side of the first leaflet and a second suture portion extending from the first loop portion proximally through the first leaflet to the ventricular side of the first leaflet;
disposing on an atrial side of a second leaflet of the mitral valve a second implant, the second implant including a second loop portion, a third suture portion extending from the second loop portion proximally through the second leaflet to the ventricular side of the second leaflet and a fourth suture portion extending from the second loop portion proximally through the second leaflet to the ventricular side of the second leaflet;
placing the first suture portion within a lumen of an inner member of a securing device;
placing the third suture portion within the lumen of the inner member of the securing device;
inserting one of the second suture portion and the fourth suture portion through a distal opening defined by an outer member of the securing device and through a side opening defined by the outer member;
forming a knot with the second suture portion and the fourth suture portion outside the securing device; and
moving the knot distally toward the ventricular side of the mitral valve using the outer member of the securing device.

Abstract
Apparatus and methods for performing a non-invasive procedure to repair a cardiac valve are described herein. In some embodiments, apparatus and methods are described herein for repairing a mitral valve using an edge-to-edge repair to secure the mitral valve leaflets. Implant securing devices are also described that can be used during a procedure to repair a mitral valve. In some embodiments, an implant securing device includes an outer member and an inner member movably disposed within the outer member. The inner member can be used to hold or secure a suture extending from an implant deployed on an atrial side of a leaflet of a mitral valve, and the outer member can be used to push or move a half hitch knot toward a ventricular side of the leaflet, which can be used to secure the implant in the desired position.

12. A method, comprising:
-
disposing on an atrial side of a first leaflet of a mitral valve a first implant, the first implant including a first loop portion, a first suture portion extending from the first loop portion proximally through the first leaflet to the ventricular side of the first leaflet and a second suture portion extending from the first loop portion proximally through the first leaflet to the ventricular side of the first leaflet; disposing on an atrial side of a second leaflet of the mitral valve a second implant, the second implant including a second loop portion, a third suture portion extending from the second loop portion proximally through the second leaflet to the ventricular side of the second leaflet and a fourth suture portion extending from the second loop portion proximally through the second leaflet to the ventricular side of the second leaflet; forming a first knot with the first suture portion and the third suture portion; moving the first knot distally toward the ventricular side of the mitral valve using a pusher device; forming a second knot with the second suture portion and the fourth suture portion; and moving the second knot distally toward the ventricular side of the mitral valve using the pusher device, the first knot and the second knot configured to secure the first implant and the second implant together to decrease the septal-lateral distance of the mitral valve annulus. - View Dependent Claims (13, 14, 15, 16)
