The flexible ultrasound wire delivered through an endoscope can bend through multiple radii and deliver ultrasonic energy to the business end of the working channel of an endoscope without requiring percutaneous incisions. The flexible ultrasonic wire is wire or fiber that can be flexed in any direction and is connected at one end to an ultrasonic transducer which is connected to an energy delivering device. An insulating layer between the flexible ultrasonic wire and a metallic working channel is non-metallic and resilient and operates to prevent unwanted fragmentation of the device and possible collateral soft tissue injuries.
