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.
