MEDICAL DEVICE CONTROL HANDLE
First Claim
1. A control handle for a medical device having an elongated body, a distal assembly distal the elongated body, the distal assembly having an adjustable configuration, the medical device further comprising a puller member extending through the elongated body and the distal assembly, the control handle comprising:
- a housing having an outer surface formed with a channel;
an actuator assembly comprising;
a user interface rotational dial;
a spool having a shaft body inserted through a through-hole in the housing, the spool having a drum on which the puller member is wound;
a detent washer mounted on the shaft body, the first washer being rotationally coupled to the dial to transmit rotational movement from the dial to the shaft body, the washer having a tab that rides in the channel to guide movement of the detent washer;
at least one friction-inducing washer mounted on the shaft body; and
a fastener mounted on the shaft body adapted to generate a compression load on the friction inducing washer.

Abstract
A medical device control handle has with a distal component which is adjustable by an actuator assembly by means of a puller member or wire. The actuator assembly includes a user interface rotational dial, a detent tab washer and a spool, where the dial is rotationally coupled to the detent tab washer which transmits rotational movement of the dial to the spool. The spool has a shaft body and a drum end onto which an proximal end portion of the puller member can be wound to manipulate or adjust the distal component. Rotational movement of the detent washer is limited to prevent overrotation and breakage of the puller member. At least one washer is mounted on the shaft body of the spool to help apply compression load on the actuator assembly in friction-inducing contact with one or more components of the actuator assembly.
