US 2026/0294452 A1 · METHOD FOR CONTROLLING A THERAPEUTIC ULTRASONIC INTERVENTIONAL SYSTEM

Abstract

A method for controlling a system, comprising repeatedly monitoring a resonant frequency of a system that includes an ultrasonic transducer, wherein the ultrasonic transducer is powered by an ultrasonic generator and is configured to drive a device at a predetermined level of resonant frequency, and wherein the ultrasonic generator includes a controller configured to monitor operational parameters of the system; detecting a change in resonant frequency based on a comparison of the monitored resonant frequency against a predetermined threshold for resonant frequency; inferring a system-use criteria based on the detected change in the resonant frequency; and adapting system control by using the controller to alter the operational parameters of the system based on the inferred use criteria.
