Abstract
Medical devices are disclosed that include a tunable ultrasonic transducer assembly, as well as related assemblies and methods. A medical device includes a transducer controller, a transducer having an input side connected with the ultrasound transducer controller via an input electrical conductor, and a tuning assembly that is electrically connected between the input electrical conductor and the ground potential. The tuning assembly is adjustable to provide a selected inductance from a number of different inductance values. The tuning assembly includes a multi-position switch and a plurality of tuning inductors. The switch is operable to select combinations of tuning inductors, thereby providing a selected inductance value between the input electrical connector and the ground potential so as inductively tune the medical device.
