Abstract
A process for therapeutic treatment of changes in human or animal bones which cause a boundary surface gap with a width of less than 5 millimeters to form between the bone and an acoustically reflective body such as an implant, a tooth or a bone fragment. The process include a first step of locating the desired boundary surface gap by means of a locating device; next the body of the patient is exposed to acoustical shock waves through the surface of the skin after focusing the shock waves on the boundary surface gap. Vibrations are generated in the bone surfaces, the surfaces of the acoustically reflecting body, and at the gap by multiple reflections of the generated shock waves. The preferred device for carrying out the process uses a therapy head to generate and focus acoustic shock waves in a predetermined direction. The shock waves are conducted through the surface of the skin into the body of the patient by a coupling unit. An x-ray beam imaging system and two targets in which the patient and two targets are placed between the source and imaging system and the two targets are connected mechanically in a moveable manner to the therapy head so that the two targets may be rotated around at least two different axis in such as way that an imaginary line connecting the two targets always passes through the focal point of the shock waves.
