TRANSAPICAL MITRAL VALVE REPAIR METHOD
First Claim
1. A method comprising:
- introducing into a ventricle of a heart proximate to a heart valve leaflet a suture having a distal portion and a proximal portion;
piercing the leaflet from a ventricular side of the leaflet to an atrial side of the leaflet to form an opening in the leaflet;
passing through the opening from the ventricular side to the atrial side the distal portion of the suture disposed in a first configuration, and with the proximal portion of the suture remaining on the ventricular side of the leaflet; and
causing the distal portion of the suture to change from the first configuration to a second configuration, the second configuration being larger than the opening in the leaflet.

Abstract
Methods and devices for repairing a cardiac valve. A minimally invasive procedure includes creating an access in the apex region of the heart through which one or more instruments may be inserted. The device can implant artificial heart valve chordae tendineae into cardiac valve leaflet tissues to restore proper leaflet function and prevent reperfusion. The device punctures the apex of the heart and travels through the ventricle. The tip of the device rests on the defective valve and punctures the valve leaflet. A suture or a suture/guide wire combination is inserted, securing the top of the leaflet to the apex of the heart. A resilient element or shock absorber mechanism adjacent to the outside of the apex of the heart minimizes the linear travel of the device in response to the beating of the heart or opening/closing of the valve.
