Devices, systems, and methods for adjustably tensioning an artificial chordae tendineae between a leaflet and a papillary muscle or heart wall

A device for adjusting tension in an artificial chordae tendineae, the device comprising:

• a body portion;
• a locking portion configured and positioned with respect to said body portion to allow movement of an artificial chordae tendineae in a first direction with respect to said body portion, while preventing movement of the artificial chordae tendineae in a second direction opposite the first direction;
• an actuator coupled to said locking portion to move a portion of said locking portion in the first direction to enable selective movement of the artificial chordae tendineae in the second direction;
• and
• wherein the actuator is a filament extending proximally to a user so that the user can activate said actuator to release said locking portion by pulling said actuator.

A system for adjusting tension in an artificial chordae tendineae, the system comprising:

• a clip engageable with a leaflet of a heart valve;
• an anchor engageable with a papillary muscle or heart wall;
• and
• an artificial chordae tendineae disposed between the clip and the anchor;
• wherein the anchor includes:
• a body portion, and
• a locking portion engageable with the artificial chordae tendineae and configured to allow movement of the artificial chordae tendineae with respect to the body portion;
• wherein the system further comprises an actuator coupled to the locking portion;
• wherein the actuator is configured to shift the locking portion between an unlocked configuration where the artificial chordae is movable relative to the body portion and a locked configuration where the artificial chordae is substantially fixed relative to the body portion;
• and
• wherein the actuator extends proximally to a user so that the user can activate the actuator by pulling the actuator.
