The system for treating an internal organ has a generator source for producing a shock wave connected to a portable shock wave applicator device, wherein the shock wave applicator device has a side-firing shock wave head having a variable angle adjustment relative to a release and lock connected handle or holder means for holding said device. The inclination of the shock wave head can be set to a fixed inclination to reach the organ at various locations or surfaces or can be pivotally inclined continuous to vary the treatment surfaces area.
