Adjustable and reversible locking mechanism for catheter-delivered implant

Abstract:

An implantable heart valve device has a main body including a first end portion and a second end portion. The main body is configured to be implanted around a native leaflet of a heart valve such that the first end portion is on an atrial side of the leaflet and the second end portion is on a ventricular side of the leaflet, and such that the main body can coapt with an opposing native leaflet during operation of the heart valve. One of the first or second end portions comprises a coupling assembly, and the other of the first or second end portions comprises a coupling member configured to extend through the native leaflet when the heart valve device is implanted in a heart valve. The coupling assembly is configured to releasably engage the coupling member to permit adjustment of the relative positions of the first and second end portions.
