Abstract: A medical introducer sheath comprises a tubular shaft and an ultrasonic transducer array. The tubular shaft has a proximal end, a distal end opposite the proximal end, an inner surface, and an outer surface. The shaft defines a longitudinal axis extending between the proximal end and the distal end. The inner surface and the outer surface define a wall having a shaft wall thickness, the wall defining a distal wall face proximate the distal end of the shaft extending at an oblique angle relative to the longitudinal axis. The ultrasonic transducer array includes a plurality of ultrasound transducers disposed within the wall of the tubular shaft at the distal end thereof. The ultrasound transducers include an emitting/receiving surface generally aligned with the distal wall face, such that ultrasonic energy emitted from each of the ultrasound transducers is oriented directed generally at an oblique angle relative to the longitudinal axis.

Abstract: The present invention encompasses apparatus and methods for mapping electrical activity within the heart. The present invention also encompasses methods and apparatus for creating lesions in the heart tissue (ablating) to create a region of necrotic tissue which serves to disable the propagation of errant electrical impulses caused by an arrhythmia.

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.
