A medical device control handle or catheter includes deflection assembly and at least one of the following: a disk actuator, a lever actuator and a ring actuator for actuating additional puller wires in manipulation of multiple features of the medical device or catheter independently of each other. The disk actuator has a common rotational axis with but is rotationally independent of the deflection assembly. The lever actuator has a separate rotational axis. The ring is mounted outside of the control handle and rotatable relative to the control handle to actuate another puller wire for manipulating another feature of the catheter. Each of the disk, lever and ring actuators are of a design that allows existing control handles and catheters to be readily modified to include these actuators.

Medical device control handle with multiple puller wires

A catheter for the treatment of tissue, particularly for the treatment of cardiac tissue to alleviate cardiac arrhythmias includes a connector having mechanical use limiter that may be placed in the handle of the catheter or at any point along the electrical connection pathway to an electro-anatomic mapping system and/or ablation system. The mechanical use limiter has a counter wheel and locking pin which when engaged disables the reconnection of the connector to any mated connector after a predetermined number of uses.
