Patent ID: 7497836

Claim:
A method of treatment for a sinus or nasal tissue exhibiting a sinusitis or rhinosinusitis disease or condition in a diagnosed patient comprises the steps of: receiving a diagnosed patient; activating an acoustic shock wave or pressure pulse generator or source to emit low energy unfocused or focused acoustic shock waves or pressure pulses in a path having a low energy density less than 1.0 mJ/mm 2 per shock wave or pressure pulse, the pressure pulse being an acoustic pulse which includes several cycles of positive and negative pressure, wherein the pressure pulse has an amplitude of the positive part of such a cycle should be above 0.1 MPa and the time duration of the pressure pulse is from below a microsecond to about a second, rise times of the positive part of the first pressure cycle in the range of nano-seconds (ns) up to some milli-seconds (ms), the acoustic shock waves being very fast pressure pulses having amplitudes above 0.1 MPa and rise times of the amplitude being below 100's of ns, the duration of the shock wave is typically below 1-3 micro-seconds (μs) for the positive part of a cycle and typically above some micro-seconds for the negative part of a cycle; and subjecting the sinus or nasal tissue, or the entire sinus or nasal region of the patient to converging, diverging, planar or near planar acoustic shock waves or pressure pulses treatment energy density and treatment dosage stimulating said tissue, in the absence of creating cavitation bubbles in the sinus or nasal tissue, wherein the tissue is positioned within a path of the emitted shock waves or pressure pulses, in the absence of any acoustic focal point or if a focal point exists, the sinus or nasal tissue is positioned away from any localized geometric focal volume or point of the emitted shock waves wherein the emitted shock waves or pressure pulses either have no geometric focal volume or point or have a focal volume or point ahead of the tissue or beyond the tissue thereby passing the emitted waves or pulses through the tissue while avoiding having any localized focal point within the tissue wherein the emitted pressure pulses or shock waves are convergent, divergent, planar or near planar and the pressure pulse shock wave generator or source is based on electro-hydraulic, electromagnetic, piezoceramic or ballistic wave generation having an energy density value ranging as low as 0.00001 mJ/mm 2 to a high end of below 1.0 mJ/mm 2 ; wherein treatment energy density and treatment dosage are selected to avoid tissue damage within the sinus or nasal tissue as evidenced by the avoidance of cell hemorrhaging, the shock waves or pressure pulses having a low treatment energy density in the range of 0.00001 mJ/mm 2 to less than 1.0 mJ/mm 2 .
