Abstract

A transducer device for therapeutic applications is disclosed. The transducer device may include a mounting body configured for mounting the device to a finger of an operator of the device. The transducer device may also include a transducer housing connected to the mounting body that defines a receiving portion. The transducer device may further include a transducer element disposed in the receiving portion that is configured for connection to an energy supply and configured to transmit energy from an emitting surface. The transducer device may further include a gas reservoir disposed between the transducer element and the mounting body that is configured to prevent transmission of energy. The transducer device may further include a membrane connected to the transducer housing and disposed adjacent the emitting surface of the transducer element, and a cooling lumen for providing fluid to the membrane. A method of applying therapeutic ultrasound is also disclosed.
