The invention relates to a shock wave applicator, especially for clinical use in oncology, comprising a first hollow cylinder electrode covered on the outer surface by a porous insulating layer, the first electrode being surrounded by a second reflector-shaped electrode. A high-voltage pulse source and an insulator are disposed between the first electrode and the second electrode.
The space between the electrodes is filled with a fluid of defined conductivity. An ultrasonic probe is slidably mounted in the cavity within the first electrode.
Furthermore, the invention relates to a shock wave delivery assembly, in particular for clinical use in oncology.
