Abstract
Apparatus is provided for adjusting at least one dimension of an implant, including a rotatable structure having first and second openings and a channel extending between the first and second openings. The channel allows passage therethrough of an elongate tool. The second end of the structure has a lower surface having one or more recesses along a circumference thereof. A mechanical element provides a protrusion that is disposed within one of the recesses of the rotatable structure during a resting state of the mechanical element, in a manner that restricts rotation of the rotatable structure. The mechanical element includes a depressible portion coupled to the protrusion disposed in communication with the second opening of the lower surface, and configured to dislodge the protrusion from within the recess in response to a force applied thereto by the elongate tool. Other applications are also described.
