Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
48 words
A method of inducing bone growth in a mammal which comprises directing acoustic shock waves to a site where bone growth is desired, the shock waves applying an amount of pressure sufficient to produce bleeding at said site, said amount of pressure being sufficient to induce bone growth.
Claim 2
Independent Claim
48 words
A method of inducing bone growth in a mammal which comprises directing acoustic shock waves to a site where bone growth is desired, the shock waves applying an amount of pressure sufficient to produce bleeding at said site, said amount of pressure being sufficient to induce bone growth.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein the shock waves have a peak amplitude pressure of at least 800 bar (8×10 7 Pa) and the intensity is about 10 5 Watt/cm 2 .
Claim 4
Dependent Claim
13 words
The method of claim 2 wherein at least 500 shock waves are applied.
Claim 5
Dependent Claim
19 words

Claim 7
Independent Claim
45 words
A method of treating osteoporosis in a mammal which comprises directing acoustic shock waves to bones which have suffered decalcification, the shock waves applying an amount of pressure sufficient to produce bleeding in said bones, said amount of pressure being sufficient to induce bone growth.
Claim 8
Independent Claim
45 words
