A cord that has been previously affixed around an annulus can be fastened with a fastener that is movable from a first state in which the cord is free to slide to a second state in which the cord is locked in place. After the fastener is moved to the second state, a cutting element with a slit shaped distal portion oriented in the distal-to-proximal direction with sharp edges slides with respect to a shelf and cuts off portions of the cord that are proximal with respect to the two locked parts.

Fastening a constricting cord in a reduced-diameter state around a cardiac valve annulus, and cutting proximal portions of the cord

A cord that has been previously affixed around an annulus can be fastened using a sliding member that locks into a housing. Before those two parts are locked together, the cord is free to slide through a channel in the sliding member, and a shear pin prevents the sliding member from moving. After those two parts are locked together, portions of the cord are squeezed between the upper surface of the sliding member and one wall of the housing, and other portions of the cord are squeezed between the lower surface of the sliding member and another wall of the housing, so that the cord can no longer slide. After locking, a sliding cutting element can be actuated to cut off portions of the cord that are proximal with respect to the two locked parts.
