An apparatus treats patients suffering from vascular disease with infra-, audible- and ultrasound waves. The apparatus includes a treating head for emitting sound waves with frequencies ranging from 1 Hz to 100 kHz and feeding introducing the sound waves through a coupling medium into a body portion to be treated, an electronics connected to the treating head for energizing the treating head to emit the sound waves, and a control panel connected to the electronics to choose the electronic waveform of the energizing.
