Abstract: A device for treating the human or animal brain with shockwaves has a shockwave transducer coupled to a position sensor for detecting the position of the shockwave transducer. The device is adapted to evaluate the signals of the position sensor to calculate the position of the focus spot of the shockwave transducer. Furthermore, a mapping device is provided for mapping the movement of the focus spot over a plurality of positions together with the applied shockwave dose at each of the positions. The applied shockwave dose may be indicated on a color display.

Abstract: A medical apparatus for treatment of the human or animal body by mechanical pressure waves or shock waves, comprising a device designed to generate the pressure waves or shock waves and having at least one applicator part that comprises an input face, to which an impact can be repeatedly applied in order to generate the pressure waves or shock waves, and that comprises an output face, from which the pressure waves or shock waves are applied into the body, said applicator part being made at least partially of plastic or ceramic. At least one weight element that increases the weight of the applicator part is arranged on the applicator part between the input and output faces, said input face and output face being made of plastic or ceramic.

Abstract: A medical apparatus for treatment of the human or animal body by mechanical pressure waves or shock waves, comprises a device designed to generate the pressure waves or shock waves. The device for generating the pressure waves or shock waves have at least one applicator part which can be subjected to impacts at a proximal end in order to generate the pressure waves or shock waves and, at a distal end, applies the pressure waves or shock waves into the body. The apparatus is additionally designed to generate outside the body, and to apply into the body, at least one further physiological action parameter chosen from the group consisting of electrical current, electro-magnetic waves, in particular light, ultrasound and/or a further mechanical action.

Abstract: A medical device for treatment of the human or animal body by mechanical pressure waves or shock waves comprises a device which generates the pressure waves or shock waves and which has at least one percussion part that can be moved to and fro, a pneumatic drive for the at least one percussion part, for applying pressure to the at least one percussion part, and at least one impact body against which the at least one percussion part strikes in order to generate the pressure waves or shock waves in the impact body, and a control system for the pneumatic drive. The control system controls the pneumatic drive during operation in such a way that the pressure during at least two successive strikes of the at least one percussion part against the impact body is applied continuously to the at least one percussion part, with the result that the at least one percussion part executes these at least two successive strikes in a time interval within a range of 2 ms to 30 ms.

Abstract: In an arrangement for the generation and focussing of shock waves for purposes of comminution of concrements, wherein the generation is provided by a pair of electrodes, and the focussing is provided by a rotational ellipsoid; the electrodes extend from a sleeve being inserted in the body of the ellipsoid such that the electrodes center on one of the two focal points of the rotational ellipsoid; a positioning device for the electrodes includes a position indicator on the electrode sleeve such as a metal or optical marking on a mechanical actuator having a highly accurately predetermined positional relation to the electrodes; a position sensor on the body of the rotational ellipsoid has a highly accurately determined position in relation to the first focal point; and a circuit is connected to the position sensor to provide a audible and/or visible representation if, and only if, the position indicator has an accurate position related to the sensor as an indication that the electrodes are centered on the first

Abstract: A mold or parts of the mold are removed from a casting following solidification and cooling by immersing the casting with mold or mold particles still attached in a liquid such as oil or water and focusing shock waves onto interface portions to obtain ablation and spalling of the mold material to be removed from the casting.

Abstract: A shock wave sensor is disclosed in which a piezoelectric foil is either suspended in a ring or on a backing. Electrodes run from a particular sensitive area on the foil towards the edges and are fracture proof connected to concentric conductors.

Abstract: A generator for pulse trains of shockwaves for the purpose of contactlessly comminuting concretions in living bodies, comprising a shockwave source, for instance a spark gap, a focusing reflector, for instance a hollow ellipsoid filled with a propagation medium, and a layer of a material having an impedance different from that of the medium of propagation mounted in such a manner that it is crossed by the shockwave field.

Abstract: In extracorporal lithotripsy a shock wave that is focussed on a concrement is followed by a pain producing pressure wave. This wave is filtered by means of a membrane bulging inwardly into the focussing chamber, closing the same and having a thickness smaller than the predominant wave length of the shock wave.
