Claim 0:
1. A device for shock wave production to treat a patient's body, comprising:
a condenser and a switch configured to discharge a pulse of electric current with a voltage in a range from 2 kV to 50 kV;
an applicator comprising:
an applicator cell providing a cavity;
at least one coil;
a conductive plate;
a single piezo-element coupled to the conductive plate and attached to the applicator cell at a bottom of the cavity;
a dielectric material positioned in the cavity, fixing the single piezo-element in the cavity; and
an acoustic lens attached to the applicator cell below the single piezo-element;

wherein the single piezo element is configured to generate at least one shock wave pulse having a duration in a range from 200 ns to 30 μs in response to the pulse of electric current;
wherein the applicator is configured to provide pressure to the patient's body in a range from 5 MPa to 250 MPa;
wherein the dielectric material has a dielectric constant in a range from 1.0005 to 2000 and dielectric strength in a range from 1 kV·mm−1 to 90 kV·mm−1;
wherein the single piezo-element has a volume in a range from 1.5 cm3 to 600 cm3; and
wherein the at least one coil and the conductive plate are separated by a spacing distance.
