Abstract
Piezo-keramische Stosswellenquelle, insbesondere für die Lithotripsie,
mit einem Träger (T), einer Vielzahl von Piezo-Elementen (P), die eben
oder kugelkalottenförmig angeordnet sind, und Kontaktierungen (Silber
leitschicht S, Anschlussdrähte A) an der Vorderseite und Rückseite der
Piezo-Elemente (P), wobei der Träger (T) die Piezo-Elemente (P) sowohl
seitlich als auch an den Rückseiten umfasst, also Isolation und Backing
ist, und aus einem Kunststoff besteht.
