Abstract
Apparatus for use with a deployment tool is provided. The apparatus includes a tissue anchor configured to be delivered in a constrained state within the deployment tool. The tissue anchor includes a shaft and a tissue-coupling element, which extends from a distal end of the shaft and is configured to be advanced through an incision in a wall of a cardiac chamber and be coupled to a far outer side of the wall. A spring is disposed proximal to a sealing element, and is configured to distally push the sealing element against an inner side of the wall to seal the incision. Other embodiments are also described.
