US Patent 9636224 Deployment techniques for annuloplasty ring and over-wire rotation tool

Apparatus is provided for use with a subject, including an implant comprising a sleeve shaped so as to define a lumen therein, the sleeve having first and second portions. A contracting mechanism is coupled to a portion of an outer surface of the sleeve in a vicinity of the first portion of the sleeve. An elongated contracting member is coupled at a first end portion thereof to the contracting mechanism, and coupled at a second end portion thereof to the sleeve in a vicinity of the second portion of the sleeve. The contracting mechanism comprises a driving interface that is positioned so as to be accessible from the portion of the outer surface of the sleeve. The contracting mechanism is configured such that rotation of the driving interface contracts the implant by tightening the elongated contracting member. Other applications are also described.
