ADJUSTABLE TETHER AND EPICARDIAL PAD SYSTEM FOR PROSTHETIC HEART VALVE

摘要

Apparatus and methods are described herein for repositioning a tether attached to a prosthetic heart valve. In some embodiments, a method includes inserting a distal end portion of a snare device through an incision at a first location in a ventricular wall of a heart and within the left ventricle of the heart. A tether extending from a prosthetic mitral valve, through the left ventricle and out an incision at a second location on the ventricular wall of the heart is snared with the snare device. The tether is pulled with the snare device such that a proximal end of the tether is moved back through the incision at the second location on the ventricular wall and into the left ventricle. The snare device is pulled proximally such that the tether is pulled proximally through the incision at the first location in the ventricular wall of the heart.

主权项

1. A method, comprising:
inserting a distal end portion of a snare device through an incision at a first location in a ventricular wall of a heart of a patient and positioning a distal end of the snare device in the left ventricle of the heart; snaring with the snare device a tether at least partially disposed within the left ventricle, the tether exiting the heart at an incision at a second location on the ventricular wall of the heart and extending from a prosthetic mitral valve implanted within a mitral annulus of the heart; pulling the tether with the snare device such that a proximal end of the tether is moved back through the incision at the second location on the ventricular wall and into the left ventricle; and pulling the snare device proximally, such that the snared tether is pulled proximally through the incision at the first location in the ventricular wall of the heart.
