Example medical devices and methods for using the medical devices are disclosed. An example ultrasound medical device includes an elongate shaft having a distal end region, a housing coupled to the elongate shaft, a first ultrasound transducer coupled to the housing, and a second ultrasound transducer coupled to the housing. Further, the first ultrasound transducer is configured to generate a first ultrasound wave, the second ultrasound transducer is configured to generate a second ultrasound wave and the first ultrasound wave constructively interferes with the second ultrasound wave to generate a localized pressure wave in order to transmit energy to a target region.
