Adjustable partial annuloplasty ring and mechanism therefor
First Claim
1. Apparatus comprising an annuloplasty ring structure configured to be implanted in a body of a subject, comprising:
- an implant structure with a coiled structure having a lumen and first and second portions, the implant structure comprising a rotatable structure coupled to the implant structure in a vicinity of the first portion thereof;
and a flexible member that does not form a closed loop disposed within the lumen of the coiled structure, the flexible member having a first portion thereof that contacts the rotatable structure, and at least one end thereof that does not contact the rotatable structure, wherein;
in response to rotation of the rotatable structure in a first rotational direction, successive portions of the first portion of the flexible member advance in a first advancement direction toward and wind around a portion of the apparatus, so that and the flexible member contracts the implant structureand, wherein the apparatus is implanted at a cardiac valve of the subject.
