SYSTEM AND METHOD FOR TISSUE INTERVENTION VIA IMAGE-GUIDED BOILING HISTOTRIPSY

Abstract: one embodiment is directed to a minimally invasive system for treating a targeted tissue structure of a patient, comprising: an electromechanical support assembly having a proximal portion and a distal portion; a computing system operatively coupled to the electromechanical support assembly; and a hifu treatment transducer array coupled to the distal portion of the electromechanical support assembly and operatively coupled to the computing system; wherein the computing system is configured to operate the electromechanical support assembly to control a position of the transducer assembly relative to the patient such that a treatment focus of the hifu treatment transducer array is aligned to treat at least a portion of the targeted tissue structure of the patient, and to operate the hifu treatment transducer array to controllably create a pulsatile wavefront of ultrasound radiation directed at the treatment focus, the pulsatile wavefront configured to produce one or more vapor bubbles within the targeted tissue structure and to controllably produce cavitation of the one of more vapor bubbles such that a controllably lysed portion of the targeted tissue structure is created.
