Abstract

This invention relates to methods for medical treatment of pathological conditions. More particularly, the invention relates to methods for using acoustic shock waves to treat a variety of pathological conditions such as plantar warts, deep bone bruises, prostate cancer, benign prostatic hypertrophy, urinary incontinence, and spinal cord injuries, including the reduction or removal of scar tissue to aid in spinal cord regrowth.

Claims

1. A method of treating scar tissue in the spinal cord comprising:

locating a site or suspected site of a pathological condition associated with said scar tissue;

generating acoustic shock waves;

focusing said acoustic shock waves on the located site; and

applying a sufficient number of acoustic shock waves to the located site to induce or accelerate healing.

2. The method of claim 1, wherein generating acoustic shock waves comprises generating about 2000 to about 6000 acoustic shock waves by applying a voltage potential across a spark gap of a spark gap generator ranging from about 14 kV to about 28 kV to generate each shock wave.

3. The method of claim 1, wherein said applying a sufficient number of acoustic shock waves comprises applying the generated acoustic shock waves in a single treatment.

4. The method of claim 1 wherein the acoustic shock waves are focused on the located site with an ellipsoid reflector, and wherein applying the acoustic.

5. A method for inducing or accelerating the generation of nerve cells in the treatment of a spinal cord injury comprising:

locating a site or suspected site of a pathological condition associated with the spinal cord injury;

generating acoustic shock waves;

focusing the acoustic shock waves on the located site; and

applying a sufficient number of acoustic shock waves to the located site to induce micro-injury and increased vascularization thereby inducing or accelerating the generation of nerve cells.

6. The method of claim 5, wherein said generating acoustic shock waves comprises generating about 800 to about 4000 acoustic shock waves by applying a voltage potential across a spark gap of a spark gap generator ranging from about 14 kV to about 28 kV to generate each shock wave.

7. The method of claim 5, wherein said applying a sufficient number of acoustic shock waves comprises applying the generated acoustic shock waves in a single treatment.

8. The method of claim 5, wherein the acoustic shock waves are focused on the located site with an ellipsoid reflector.
