Abstract: A subcutaneous tunneling and carrying tool has a handle, a rod, and a carrier. The tool is used in connection with the implantation of electrical stimulators within the body, and more particularly facilitates the surgical procedure in the connection of an electrode lead extension to the implantable stimulator when the electrode and stimulator may not be co-located. In one embodiment, tunneling is accomplished by a tip that also serves to connect the tool to a disposable carrier in which the lead extension connector is packaged. In another embodiment the carrier comprises a carrier body and a removable cover, wherein the carrier cover covers a carrier cavity during tunneling and includes a tunneling end, and the carrier cover is removed after tunneling to expose the carrier cavity, into which carrier cavity the electrode lead extension is inserted to carry back through the tunnel.

Abstract: An ultrasonic medical device comprises an ultrasonic vibration generator that generates vibration along its longitudinal axis. The ultrasonic vibration is transmitted through an ultrasonic coupler and a series of transformer sections that amplify the ultrasonic vibration. A flexible member is coupled to the distal end of the transformer sections, and is thus supplied with a longitudinal vibration at its base by the transformer sections. The flexible member is designed so that it converts the longitudinal vibration into a standing wave that runs along the length of the flexible member. The standing wave produces a series of nodes and anti-nodes along the length of the flexible member. Each of the anti-nodes produces cavitation in fluids in contact with the probe. The cavitation of the fluids causes destruction of adjacent tissue. In this manner, the entire length of the flexible member becomes a working surface that may be utilized for destroying tissue.
