Post-Implantation Tension Adjustment in Cardiac Implants
First Claim
1. A method of treating a heart of a patient, comprising:
- implanting a first tissue anchor in cardiac tissue of the patient, the first tissue anchor attached to one or more tethers that are fixed to a coupling element;
implanting a second tissue anchor in the patient;
coupling the coupling element to a first coupling site of the second tissue anchor, thereby coupling the first tissue anchor to the second tissue anchor via the one or more tethers; and
thereafter, after allowing at least 24 hours for tissue growth on the first tissue anchor to strengthen anchoring of the first tissue anchor in the cardiac tissue, increasing tension between the first and the second tissue anchors by decoupling the coupling element from the first coupling site and coupling the coupling element to a second coupling site of the second tissue anchor.

Abstract
A method of treating a heart of a patient is provided, including implanting a first tissue anchor in cardiac tissue of the patient, the first tissue anchor attached to one or more tethers that are fixed to a coupling element. A second tissue anchor is implanted in the patient. The coupling element is coupled to a first coupling site of the second tissue anchor, thereby coupling the first tissue anchor to the second tissue anchor via the one or more tethers. Thereafter, after allowing at least 24 hours for tissue growth on the first tissue anchor to strengthen anchoring of the first tissue anchor in the cardiac tissue, tension is increased between the first and the second tissue anchors by decoupling the coupling element from the first coupling site and coupling the coupling element to a second coupling site of the second tissue anchor. Other embodiments are also described.
