Guiding for a therapeutic head for a medical shock wave generator includes a curved rail and a support for a plurality of rollers; the rail is provided with a plurality of grooves, and stainless steel wires are inserted in these grooves and project therefrom to serve as tracks in that the rollers run on the wires; in one version (FIG. 2, 3) the therapeutic head is mounted to the rail while the roller support is stationary; in an alternate version (FIG. 4 ) the relation is reversed.

Curved guiding of a lithotripsy head

A method and apparatus checks and adjusts the relative position of electrodes which form a so-called underwater spark gap device, particularly for medical purposes, and in which one electrode is fastened to the base part by means of at least one electrode holder. The method and apparatus employ an adjusting arrangement which positions the electrodes at a desired position with respect to axial displacement, angularity between the axes, and electrode spacing. By means of a relative movement of the adjustment arrangement, in a direction which is vertical with respect to an electrode axis, the electrode holder or holders are plastically deformed in such a manner that the electrodes, after the rebounding of the electrode holder or holders, are located at the desired position.
