Abstract (en)
[origin: EP0298334A1] Shock-wave generator for treating concrements in the body of a patient, with a fluid-filled shock-wave tube (1), one end of which is sealed by a flexible bag (2) and at the other end of which is situated a diaphragm (3) with electrically conductive material, which is repelled by a flat coil (6) for generating high-voltage pulses. The intention is to achieve a favourable shock-wave characteristic. <??>The diaphragm (3) has a flexible base (9) which is covered by a multiplicity of small plates (10) of conductive material. The small plates (10) can have differing inertia and/or electrical conductivity. <??>The shock-wave generator can be used for treating kidney stones. <IMAGE>
