ABSTRACT:
A method and device for treating wounds10of tissue11is disclosed. The method has the steps of applying a porous pad12upon the treatment surface of the tissue11; covering the treatment surface and the porous pad12with a foil or sealing cover14for isolating the treatment surface and the porous pad12from the atmosphere; filling the volume under the foil or sealing cover14with fluid100and purging air from the volume under the foil or sealing cover14thereby fluid100saturating said porous pad12: applying an acoustic shock wave treatment through the foil or sealing cover14or surrounding tissue11or a combination thereof sending acoustic shock waves200through the volume to the treatment surface and underlying tissue11and thereafter pulling a vacuum to create a sub-atmospheric pressure under the foil or sealing cover14wherein the combination of the applied acoustic shock waves200and sub-atmospheric conditions stimulates healing of the treatment surface and underlying tissue11. Preferably the acoustic shock waves200are unfocused or a wide area focused shock wave pattern. More preferably the shock waves200are sufficiently low energy or amplitude to avoid the sensation of pain during the treatment process thereby eliminating the need for anesthesia or localized numbing of the treatment area.
