    摘要： 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.

    摘要： Method and apparatus for control of ablation energy and electrogram acquisition through multiple common electrodes in an electrophysiology catheter. A device that routes ablation energy to and that routes mapping signals received from an electrophysiology catheter having a plurality of conductive filaments including circuitry that provides, for each conductive filament when ablation energy is being delivered, an electrical signal path that has a low impedance for ablation energy and a high impedance for mapping signals. The device also includes circuitry that provides, for each conductive filament, when mapping signals are being received, an electrical signal path that has a high impedance for ablation energy and low impedance for mapping signals. At least one switch is provided that selectively groups electrodes into sectors for delivery of ablation energy.
