The shaft extends from a distal end of the handle. The end effector is coupled to a distal end of the shaft. The wire extends from the handle, through the shaft, and to the end effector.

Distal movement of the spool moves the wire distally independent of the shaft and transitions the end effector between at least a first configuration and a second configuration. Proximal movement of the spool urges the wire proximally. Urging the wire proximally deflects a deflectable portion of the shaft in one or more directions.
