Safety and Initial Efficacy Study of the Vortx Rx for Treatment of Benign Prostatic Hyperplasia (US)

Non-invasive histotripsy treatment/therapy to be delivered by the surgeon using very low duty cycle ultrasound pulses from outside the patient's body. These pulses form a bubble cloud at the end of the focal area within the prostate which mechanically breaks up the cellular structure of the soft tissue. During treatment, a surgeon is able to direct the bubble cloud throughout the targeted volume using controls located on the device console and using the real-time ultrasound for visualization feedback and control of the bubble cloud location.
