Abstract: An ultrasonic transducer driving circuit configured to supply an output current and/or an output voltage to an output line for driving an ultrasonic transducer is provided. The ultrasonic transducer driving circuit includes a first current discharge circuit configured to allow a current arising from electric charges accumulated in the ultrasonic transducer to flow from the output line to ground when the output line is at a positive voltage, and a second current discharge circuit configured to allow the current arising from the electric charges accumulated in the ultrasonic transducer to flow from ground to the output line when the output line is at a negative voltage. The first current discharge circuit and the second current discharge circuit are controlled based on the output current and/or the output voltage.

Abstract: Medical tool positioning and control devices, systems, and methods. Handle assemblies that allow a steerable shaft to be steered, while allowing the separate movement of a medical tool. The handle assemblies can allow for rotation and axial movement of the medical tool, and optionally with an actuator disposed distal to a second actuator that controls steering of the steerable shaft.
