1. Apparatus comprising:
- an implant structure, which comprises a contracting mechanism, which comprises;
a rotatable structure, which comprises a spool; and
a flexible contracting member having a first portion wound around the spool, and a second portion that extends at least along a portion of the implant structure, wherein the spool is arranged such that rotation of the spool contracts the implant structure by winding the contracting member around the spool;
a longitudinal member, which is coupled to the contracting mechanism; and
a tool for rotating the rotatable structure, the tool configured;
to be guided along the longitudinal member toward the contracting mechanism while the longitudinal member is coupled to the contracting mechanism,after being guided along the longitudinal member, to contact and engage the rotatable structure while the longitudinal member is coupled to the contracting mechanism, andto increase a number of times the contracting member is wound around the spool by rotating the rotatable structure in response to a rotational force applied to the tool.

Abstract
Apparatus is provided that includes an implant structure, which includes a contracting mechanism, which includes a rotatable structure, arranged such that rotation of the rotatable structure contracts the implant structure. A longitudinal member is coupled to the contracting mechanism. A tool for rotating the rotatable structure is configured to be guided along the longitudinal member, to engage the rotatable structure, and to rotate the rotatable structure in response to a rotational force applied to the tool. Other embodiments are also described.
