Abstract
A tissue anchor comprises an anchoring portion, and a crown coupled thereto. The crown includes an anchor head fixedly coupled to the anchoring portion, a driver interface, and a socket. The socket may be fixedly coupled to the driver interface and shaped to receive the anchor head. In a first state the anchor head is seated snugly within the socket, such that torque applied to the driver interface is transferred to the anchoring portion, thereby facilitating screwing of the anchoring portion into the tissue. Screwing of the anchoring portion into the tissue can pull the anchor head distally out of the socket, thereby transitioning the anchor into a second state in which torque applied to the driver interface rotates the socket relative to the anchor head and the anchoring portion. Other embodiments are also described.
