摘要：
Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.
