Tissue anchor for annuloplasty device
First Claim
1. Apparatus, comprising:
- an implant configured to be coupled to cardiac tissue of a patient, the implant comprising;
a sleeve;
a spool coupled to the sleeve; and
a flexible contracting member that is coupled to the spool and to the sleeve, such that winding the contracting member around the spool tightens the contracting member; and
a tissue anchor comprising;
a distal tissue coupling element configured to couple the tissue anchor to the cardiac tissue of the patient; and
a proximal implant-receiving element configured to receive at least a portion of the implant and facilitate coupling of the implant to the tissue anchor, the proximal implant-receiving element comprising;
an implant-restraining element being configured to restrain the implant from separating from the proximal implant-receiving element; and
an elastic portion that is configured to assume a first length when relaxed, and a second, greater length when under load;
wherein, the implant-restraining element and the elastic portion restricts proximal movement of the implant along the proximal implant-receiving element.
