Abstract: An electrode arrangement is provided having at least one electrode for insertion into a human or animal body for electrothermal treatment of the body. The electrode is situated on an electrode support and is connected to an alternating current source via a supply lead and to a temperature stabilizer device for influencing the effective temperature profile in the treatment area. The electrode support and the electrode, or electrodes, are constructed for direct insertion into the body tissue, said insertion being channel forming. The temperature stabilizer device has a timed heating device for thermal support of the insertion.

Abstract: A muscular tissue revascularizing apparatus. First electrodes generate a heat effect into the muscular tissue. Second electrodes generate pulsed spark discharge shockwaves into the muscular tissue.

Abstract: An arrangement (1) for electrothermally treating the human body or an animal body, in particular for tissue coagulation or electrotomy, includes two electrodes (3, 4) for insertion into the body to be treated. The two electrodes (3, 4) are electrically insulated from each other and are disposed at a distance from each other to produce an electric or electromagnetic field heating the body tissue in the treatment area, and each electrode is connected by a feed line with a power source arranged outside the body. An elongate catheter (2) is provided for joint insertion of the two electrodes (3, 4) into the body, which are staggered in relation to each other in the axial direction of the catheter (2) and connected to the catheter (2) or a component thereof.

Abstract: There is provided a manually actuable ultrasonic disintegrator for the removal of human or animal tissue, which includes a sonotrode for the transmission of sound waves at its distal end to the tissue, an ultrasonic transducer which can be coupled to the sonotrode and a passage which extends lengthwise of the sonotrode for flushing and/or sucking away disintegrated or ablated tissue. In order to provide for the most effective possible application of ultrasonic waves into the tissue to be treated, the distal end of the sonotrode is in the form of a full surface outside which the flushing or suction removal passage extends.

Abstract: A cutting device for use in electrotomy is disclosed for use with a high frequency generator to make a cut in a cutting direction. The cutting device comprises a carrier element, and first and second electrodes each connected to the high frequency generator. Each electrode has a proximal portion attached to the carrier element and an elongated distal leg portion which terminates in a distal end. An insulation element connects the distal ends to each other with predetermined spacing between them. The elongated segments oppose each other and are aligned to be co-linear with each other along the cutting direction.
