Tool for actuating an adjusting mechanism

摘要

Apparatus is provided, including a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and at least a portion of an annuloplasty ring structure. The tissue-adjusting member includes an adjusting mechanism that is configured to adjust a tension of the tissue-adjusting member. The adjusting mechanism includes a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism. An elongate member is configured to maintain the locking mechanism in an unlocked state during adjusting of the tension of the tissue-adjusting member by the adjusting mechanism, and facilitate locking of the adjusting mechanism by the locking mechanism. A tool is configured to facilitate actuation of the adjusting mechanism to adjust the tension of the tissue-adjusting mechanism. The elongate member and the tool are slidably coupled with respect to each other. Other applications are also described.

1. Apparatus, comprising:
an implant comprising a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and at least a portion of an annuloplasty ring structure, the implant further comprising an adjusting mechanism that is configured, upon actuation thereof, to adjust a tension of the tissue-adjusting member, the adjusting mechanism: (1) comprising a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism, and (2) being shaped so as to define an interface; an elongate member configured to:
directly contact a portion of the locking mechanism and by the contact apply an unlocking force to the portion of the locking mechanism to maintain the locking mechanism in an unlocked state during adjusting of the tension of the tissue-adjusting member by the adjusting mechanism, andfacilitate locking of the adjusting mechanism by the locking mechanism; and a tool configured to actuate the adjusting mechanism via direct contact of the tool with the interface and application of an actuation force by the tool to the interface, while the elongate member applies the unlocking force to the portion of the locking mechanism, wherein the elongate member and the tool are longitudinally slidably coupled with respect to each other.
