Abstract (en)

[origin: EP0372198A2] Piezoceramic shock-wave generator, in particular for lithotripsy, comprising a carrier (T), a multiplicity of piezoelements (P), which are arranged flat or in the form of spherical segments, and contacts (silver conducting layer S, connecting wires A) on the front and rear of the piezoelements (P), the carrier (T) surrounding the piezoelements (P) both laterally and at the rear, thus being insulation and backing, and consisting of a plastic.
