Pressure pulse/shock wave apparatus for generating waves having plane, nearly plane, convergent off target or divergent characteristics
DCFirst Claim
1. Apparatus for generating pressure pulse/shock waves comprising:
- a pressure pulse/shock wave (PP/SW) source;
a housing enclosing said PP/SW source; and
an exit window from which shock wave fronts of waves generated by said PP/SW source emanate, wherein said shock wave fronts have plane, nearly plane, convergent off target or divergent characteristics wherein the apparatus is shaped and dimensioned to provide the shock wave fronts having a power density level to produce a tissue reaction in a subject to which the wave is administered and wherein the waves have a power density in the range of approximately 0.01 mJ/mm2 up to 1.0 mJ/mm2 to stimulate a living tissue while avoiding tissue damage.

Abstract
An apparatus for generating pressure pulse/shock waves (PP/SWs) is disclosed which comprises a pressure pulse/shock wave (PP/SW) source, a housing enclosing said PP/SW source, and an exit window from which wave fronts of waves generated by said PP/SW source emanate. The wave fronts have plane, nearly plane, convergent off target or divergent characteristics. In one embodiment, an extracorporeal shock wave system provides a planar wave for the treatment of tissue. A parabolic reflector is provided in order to propagate the planar wave through a membrane and to the tissue of a human subject. A piezoelectric, electrohydraulic or electromagnetic source may be used to develop the wave.

20. A therapeutic device for administering a shock wave to produce a living tissue reaction in a subject comprising:
-
a housing; a shock wave source disposed in the housing; wave directing and shaping structure in the housing responsive to the shock wave for causing a planar shock wave to be emitted from the housing and transferred to a living tissue; structure for coupling the shock wave to the subject; and wherein the device is shaped and dimensioned to provide the planar shock wave having a power density level to produce a tissue reaction in a subject to which the wave is administered and wherein the shock wave has a power density in the range of approximately 0.01 mJ/mm2 up to 1.0 mJ/mm2 to stimulate the living tissue while avoiding tissue damage. - View Dependent Claims (21, 22, 23, 24)
