Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a housing; a catheter shaft and an actuator coupled to the catheter shaft and configured to move longitudinally relative to the housing and longitudinally move the catheter shaft in response to force imparted by a user. The apparatuses, systems, and methods may also include a piston assembly arranged within the housing and configured to receive the actuator and allow longitudinal movement of the actuator relative to the housing.

Steerable catheter handle design

Embodiments of the invention relate to electrophysiology catheters and methods of using the same. According to one embodiment, the catheter includes a braided conductive member at its distal end that can be radially expanded, for example using a mandrel slidably disposed within a shaft of the catheter. According to another embodiment, the catheter comprises a tip portion constructed of an elastomeric material. According to a further embodiment, the catheter includes a braided conductive member wherein a thermocouple is formed using one filament of the braided conductive member and one thermocouple wire. Other embodiments of the invention relate to a handle for use with a catheter and methods of using the same. According to one embodiment, the handle comprises a thumbwheel coupled to a housing, a spring disposed within the housing in contact with the thumbwheel, and means for increasing compression of the spring to increase rotational friction on the thumbwheel.
