Patent ID: 8792962

Claim:
A catheter comprising: an elongated body; a distal member distal the elongated body, the distal member having a support member and a configuration; a control handle proximal the elongated body and having a longitudinal axis; a magnetic-based sensor assembly including at least one coil member that is wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system, and the joint region provides strain relief to the at least one coil member and the respective cable member from detaching; and 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; and a 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 puller member via the pulley to change the configuration of the distal member.
