Abstract: A device for producing electrical discharges in an aqueous medium which comprises a first electrode and a second electrode comprised of a superalloy having a cobalt content of greater than 8% by weight or optionally a nickel content of greater than 8% by weight. A high electrical voltage is applied to the electrodes to produce a voltage discharge into the medium that creates a pressure wave in the medium. The electrodes of the device exhibit high thermal shock resistance during discharge thereby reducing tip burnout.

Abstract: A medical system for treatment with focussed acoustic waves having a locating device, a therapy device, a patient positioning device, power supply devices for these devices. The complete system is installed in an integrated manner and adjusted on a common equipment carrier. The carrier frame corresponds in width and length to the projected floor area of a standard hospital bed so that the complete system can be easily transported in its mounted and adjusted state.

Abstract: A device for generating acoustic shock waves, comprising at least two electrodes which form a spark discharge gap G in a fluid volume and a reflector for the acoustic shock waves generated during the spark discharge made of an electrically conductive material, and wherein the power to one of the electrodes is supplied by way of the reflector.

Abstract: Acoustic shock waves for medical uses are generated by an electrical discharge between two electrodes, which are mounted in a liquid medium. A catalyst is added to the liquid medium in the area of the electrodes; this catalyst partially or completely catalytically converts the gas which forms upon application of the voltage to the electrodes back into its original state or partially or completely prevents the formation of the gas.

Abstract: An apparatus for administering ultrasonic shockwaves for medical use includes treatment head for focussing acoustic shockwaves at concretions in human bodies. Clinical treatment often requires two or more treatment heads or several different types of treatment heads with different power requirements to produce fragmentation of concretions. Connectors attached to treatment head cables are provided with electronics containing codes for identifying the type and characteristics of each treatment head and for transmitting that date to a power supply unit. A microprocessor in the power supply unit uses the data provided by the treatment head to automatically deliver the appropriate power ensuring that the treatment head will deliver the correct ultrasonic dose.In another embodiment, electronics are embedded in the treatment heads to provide the same function as described above.
