Abstract
To electrically and simultaneously form a plurality of focused regions of shock waves, a shock wave generating apparatus comprises: a plurality of high-voltage pulse generators for generating a plurality of high-voltage pulses; a shock wave generating unit having a plurality of ultrasonic vibrating element groups, coupled to the plurality of high voltage pulse generators, for generating shock waves and for focusing the shock waves onto a plurality of different focused regions within a biological body under examination; and a plurality of delay units coupled via the high-voltage pulse generators to the plural ultrasonic vibrating element groups, for causing the plurality of high-voltage pulses having predetermined delay times to be generated from the high-voltage pulse generators, whereby the plural focused regions are simultaneously formed juxtaposed each other near a concretion to be disintegrated with the biological body.
