Abstract

The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient. A system for adjusting tension in an artificial chordae tendineae includes an artificial chordae tendineae coupleable between a clip and an anchor. The clip is engageable with a leaflet of a heart valve while the anchor is engageable with a papillary muscle or heart wall. The anchor includes a body portion, and a locking portion coupleable with the artificial chordae tendineae and configured to allow movement of the artificial chordae tendineae in a first direction while preventing movement of the artificial chordae tendineae in a second direction opposite the first direction. An actuator is coupled to the locking portion for selectively releasing the locking portion to enable selective movement of the artificial chordae tendineae in the second direction.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Patent Application 62 / 873,352, filed July 12, 2019; and U.S. Provisional Patent Application 62 / 870,343, filed July 3, 2019, which The entire content of is incorporated herein by reference for all purposes. technical field [0003] The present invention generally relates to the field of medical devices for anchoring to the heart wall. In particular, the present invention relates to medical devices, systems and methods for delivering artificial chordae within a patient. Background technique [0004] Mitral valve disease is usually repaired via invasive surgical intervention or mitral valve replacement by intricately clipping the leaflets together, creating a double smaller opening or native valve. These methods involve risky bypass surgery that may include openings into the patient's chest and ventricle to expose the mitral valve ...
