Spark Gap technology: the shock waves are generated under water using an electrode placed in an ellipsoid reflector.The energy produced from the spark discharge is reflected and concentrated at a second focal point (F2)

Technology used in Medispec’s E3000TM Lithotripsy Device.


When electricity is applied to the coil, the metallicmembrane is repelled to the opposing magnetic field, creating shock waves. The shock waves are transmitted to the focal point by an acoustic lens or a parabolic reflector.

Piezoelectric / Sphere

Ceramic elements are lined on a reflector dish. As these elements are activated by high-voltage electric currents they generate shock waves in a fluid medium. These shock waves are reflected off the reflector dish and are localized to a focal point.
