A method for use with a heart of a subject includes advancing a tool distally along a flexible elongate contracting member, toward an anchor implanted at the heart. Tension is applied to the contracting member such that the contracting member slides proximally through a fastener disposed at the heart while a stop coupled to the fastener maintains the fastener in an open state. Using the tool, the stop is pulled proximally (i) away from the fastener, such that the fastener responsively clamps to the contracting member, thereby locking the tension in the contracting member, and (ii) against a cutting element of the tool such that the cutting element moves in a manner that severs the contracting member. Other embodiments are also described.

Fastener and techniques therefor

Apparatuses and systems are provided including a contracting member fastener. The contracting member fastener can surround the contracting member and include a clamping structure that is biased toward assuming a closed state to clamp onto the contracting member passed therethrough. A stop can be removably coupled to the fastener and maintain the fastener in an open state. A contracting-member-uptake tool can include static and dynamic cutting elements and graspers configured to pull stop proximally such that the stop pushes against and moves the dynamic cutting element with respect to the static cutting element in order to facilitate severing of the contracting member. Other applications are also provided.
