Tissue anchor for annuloplasty device

摘要

Apparatus for use with an implant configured to be coupled to cardiac tissue of a patient, the apparatus including: a tissue anchor including: 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 includes an implant-restraining element coupled to a portion of the implant-receiving element, the implant-restraining element being configured to restrain the implant from separating from the implant-receiving element. Other applications are also described.

1. Apparatus for use with an implant configured to be coupled to cardiac tissue of a patient, the apparatus comprising:
a tissue anchor comprising:
a distal tissue coupling element configured to couple the tissue anchor to the cardiac tissue of the patient; anda 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 coupled to a portion of the implant-receiving element, the implant-restraining element being configured to restrain the implant from separating from the implant-receiving element, the implant-restraining element comprising a barb configured to restrict proximal movement of the implant along the implant-receiving element, the barb comprising one or more arms that are radially expandable to rest against an external surface of the implant following coupling of the implant to the implant-receiving element.
