Claim:
1. A medical device comprising: an elongated body; a deflectable section distal the elongated body; a member distal the deflectable section, the member having a configuration; a control handle proximal the elongated body, the control handle having a longitudinal axis; a deflection assembly comprising a deflection arm rotatable about a deflection axis generally transverse to the longitudinal axis of the control handle; a control assembly comprising a rotational cam, a shaft, and a pulley, the rotational cam being in a circumferential relationship with a portion of the control handle and adapted for rotation about the longitudinal axis, the rotational cam having an inner surface with two opposing helical tracks, the portion of the control handle having two opposing linear guide slots extending in parallel with the longitudinal axis, the shaft extending along a diameter of the portion of the control handle generally perpendicular to the longitudinal axis, the shaft having two opposing ends, each of which extends through a respective guide slot and is received in a respective helical track, the pulley being mounted on the shaft; first and second puller members responsive to rotation of the deflection assembly such that rotation of the deflection arm results in deflection of the deflectable section, and a third puller member wrapped about the pulley, wherein rotation of the rotational cam about the longitudinal axis by a user actuates movement of the shaft relative to the control handle along the longitudinal axis, thereby acting on the third puller member via the pulley to change the configuration of the member.
