Abstract: A catheter includes a shaft; a tip disposed at a distal end of the shaft; at least one acoustic sensor disposed on or in the shaft, each acoustic sensor disposed at a respective distance from the distal end of the shaft; and at least one electrical conductor disposed on or in the shaft, each electrical conductor electrically connecting a respective acoustic sensor to one or more electrical connection points in a housing attached to a proximal end of the shaft. The catheter and an acoustic source are localized with respect to each other using acoustic signals transmitted between the acoustic source and the catheter.

Abstract: This invention relates generally to an ultrasound device configured to generate a frustum-shaped beam capable of fragmenting a plurality of biomineralizations located within a patient's body in combination with synthetic cavitation nuclei. The ultrasound device includes a transducer assembly comprising a plurality of ultrasound transducer elements, and a multi-channel amplifier circuit. Each channel of the multi-channel amplifier circuit is configured to actuate a distinct subset of the plurality of transducer elements. The multi-channel amplifier circuit is configured to operate in each of a plurality of states, each state of comprising a set of frequencies at which each channel of the multi-channel amplifier circuit is configured to actuate the distinct subset of transducer elements. The multi-channel amplifier circuit is further configured to switch between the plurality of states, thereby causing the plurality of ultrasound transducer elements to produce a frustum-shaped beam.
