Abstract
The production of shock-waves is triggered by using the cushion that couples acoustically and, incidentally physically, a shock-wave generator to the body of a living being; any pressure variations in the cushion are detected at a particular phase and used for triggering the generation of shock-waves. The pressure level in the cushion is kept constant, on a long term-basis, and at a level about which breath-induced pressure variations occur.
