Abstract
Devices and methods for generating acoustic shock wave within a cavity is disclosed. The shock wave device optionally includes a housing having a cylindrical portion and a cone frustum portion. The housing optionally forms a cavity configured to receive a body appendage. The shock wave device optionally includes a plurality of shock wave generators and a coupling assembly having a deformable sac configured to hold shock wave transmitting liquid. The volume of the transmitting liquid is optionally increased or decreased as needed so that the coupling assembly can conform to the shape of the body appendage. The shock waves generated optionally has an intensity gradient within the cavity of the shock wave device, where the intensity gradient is optionally controllable using a control and power supply unit.
