Abstract
Apparatus is provided that is configured to be implanted in a body of a subject, comprising an implant structure having first and second portions thereof, a spool coupled to the implant structure in a vicinity of the first portion thereof, and a flexible member coupled at a first end thereof to the spool, and not attached at a second end thereof to the spool. The flexible member, in response to rotation of the spool in a first direction thereof, is configured to be wound around the spool, and, responsively, to pull the second end of the flexible member toward the first end of the implant structure, and responsively to draw the first and second portions of the implant structure toward each other. Other embodiments are also described.

Apparatus configured to be implanted in a body of a subject, comprising:
- an implant structure having first and second portions thereof;
- a spool coupled to the implant structure in a vicinity of the first portion thereof;
- and
- a flexible member coupled at a first end thereof to the spool, and not attached at a second end thereof to the spool, the flexible member:
- in response to rotation of the spool in a first direction thereof, configured to be wound around the spool, and, responsively, to pull the second end of the flexible member toward the first end of the implant structure, and responsively to draw the first and second portions of the implant structure toward each other.
A method, comprising:
- providing an implant structure having first and second portions thereof, the implant structure including:
- a spool coupled to the implant structure in a vicinity of the first portion of the structure;
- and
- a flexible member coupled at a first end thereof to the spool, and not coupled at a second end thereof to the spool;
- advancing the implant structure, in a first configuration thereof, toward an annulus of the subject;
- coupling the structure to the annulus;
- and
- rotating the spool, and thereby:
- winding a portion of the flexible member around the spool;
- contracting the implant structure by pulling on the second end of the flexible member and thereby drawing the first and second portions of the implant structure toward each other;
- and
- contracting the annulus.
