    Abstract: A catheter including control, localization, and/or fluid delivery features, and methods of using the same. One embodiment is directed to an electrophysiology catheter including a superelastic wire and a cable, and a method of controlling the catheter using the cable. Another embodiment is directed to an electrophysiology catheter including an adhesive to bias the orientation of the catheter. A further embodiment is directed to an electrophysiology catheter including adhesive and one or more cables, and a method of controlling the catheter using the one or more cables. Another embodiment is directed to a method including acts of injecting a fluid into the heart of a patient and adjusting the diameter of an arcuate curve of the catheter. Further embodiments are directed to a catheter having multiple position sensors on an arcuate curve of the catheter, or a position sensor associated with a movable electrode of the catheter.

    Abstract: A catheter includes a fluid network for cooling the ablation electrode, surrounding blood and tissue. The fluid network comprises a circumferential channel having an annular shape and fluidly coupled to at least one proximal longitudinal channel configured to conduct fluid along a proximal length of the catheter. The circumferential channel is configured to conduct fluid about at least a circumferential portion of the catheter. The fluid network further comprises a plurality of distal longitudinal channels fluidly coupled to the circumferential channel, with the plurality of distal longitudinal channels being configured to conduct fluid a long a distal length of the catheter. The fluid network occupies a region of the catheter peripheral to a central longitudinal axis of the catheter such that other components of the irrigated catheter, including at least one imaging sensor, is disposed within the central region of the ablation electrode.
