Abstract:

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.
