Patent ID: 10492909

Abstract:
A method is provided including inserting into a heart a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and an annuloplasty ring structure. An adjusting mechanism of the tissue-adjusting member adjusts tension of the tissue-adjusting member. The adjusting mechanism: (a) includes a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism, and (b) is shaped to define a first coupling. The method further includes, using a tool reversibly coupled to the adjusting mechanism, restricting the adjusting of the tissue-adjusting member by the adjusting mechanism, by facilitating movement of the locking mechanism into a locked state. The tool is shaped to define a second coupling that mates with the first coupling of the adjusting mechanism. The first and second couplings are coupled together and remain mated during the restricting of the adjusting of the tissue-adjusting member.
