Abstract
The treatment of various sensitive organs with low energy acoustic shockwaves has been proposed. However, the prior art is lacking in guidance as to what constitutes an efficacious minimum dosage or a safe maximum dosage for various target organs and tissues. Through extensive experimentation with cultured cells, live animals, and animal disease models, the inventors of the present disclosure have determined safe and efficacious shockwave energetic dosage ranges for vital and sensitive organs, including the brain, pancreas, kidneys, liver, and spleen, as well as for skin and subcutaneous tissues, peripheral nerves, and skeletal muscles.
Claims15
A method of treating or preventing a condition caused by the weakening of skeletal muscle in the pelvic floor region of an animal by administering to the animal a dosage of low energy acoustic shock waves, wherein
- the dosage comprises a number of shockwaves delivered;
- an energy flux density of the shockwaves received by the treated skeletal muscle;
- and a frequency of shockwave delivery;
- energy received by the treated skeletal muscle from the dosage of low energy acoustic shock waves is sufficiently high to induce an increase in the proliferation rate of cells within the treated muscle;
- energy received by the treated skeletal muscle from the dosage of low energy acoustic shock waves is sufficiently low that it does not induce an observed apoptotic frequency in the treated skeletal muscle of greater than 1.0% and/or an observed frequency of hemorrhage greater than 0.12 hemorrhage spots per mm2 tissue section;
- the dosage is a biologically effective dosage calculated as the product of:
- the number of shockwaves delivered;
- the energy flux density of the shockwaves received by the treated muscle;
- and Hzk, wherein Hz is the frequency of shockwave delivery in Hertz and k is approximately 0.373;
- the biologically effective dosage is between 0.2 and 886.0 mJ/mm2;
- and
- wherein the dosage of low energy acoustic shockwaves is applied to pelvic floor region of the animal.
A method of treating or preventing a disease condition in a region of the brain of an animal by administering a dosage of low energy acoustic shock waves, wherein
- the dosage comprises a number of shockwaves delivered;
- an energy flux density of the shockwaves received by the treated region of the brain;
- and a frequency of shockwave delivery;
- energy received by the treated region of the brain from the dosage of low energy acoustic shock waves is sufficiently high to induce the proliferation rate of cells within the treated tissue;
- the energy received by the treated region of the brain from the dosage of low energy acoustic shock waves is sufficiently low that it does not induce an observed apoptotic frequency in the treated tissue of greater than 0.26% and/or an observed frequency of hemorrhage greater than 0.035 hemorrhage spots per mm2 tissue section;
- the received dosage is a biologically effective dosage calculated as a product of:
- the number of shockwaves delivered;
- the energy flux density of the shockwaves received by the organ;
- and Hzk, wherein Hz is the frequency of shockwave delivery in Hertz and k is approximately 0.373;
- and
- the biologically effective dosage is between 0.2 and 11.0 mJ/mm2;
- and the applied dosage is 10% higher than the desired received dosage at the target site for every millimeter of bone thickness that must be traversed.
