1. A method, comprising:
- coupling, to a first portion of tissue of a patient, a distal tissue coupling element of a tissue anchor, which tissue anchor further includes (a) an implant-coupling element, and (b) a cord, which is removably coupled to the implant-coupling element;
advancing an implant over the cord until the implant reaches and is coupled to the implant-coupling element; and
restraining the implant from separating from the implant-coupling element, with an implant-restraining element of the implant-coupling element wherein;
the implant-coupling element includes a barb,advancing the implant comprises pushing the implant along the barb and, by the pushing, penetrating the barb through the implant; and
restraining the implant comprises restraining the implant by the penetrating of the barb through the implant.

Abstract
A method is provided, including coupling, to a first portion of tissue of a patient, a distal tissue coupling element of a tissue anchor. The tissue anchor further includes (a) an implant -coupling element, and (b) a cord, which is removably coupled to the implant-coupling element. The method comprises advancing an implant over the cord until the implant reaches and is coupled to the implant-coupling element. The method further includes restraining the implant from separating from the implant-coupling element, with an implant-restraining element of the implant-coupling element. Other applications are also described.
