Patent ID: 7840272

Claim:
A method for modulating development or repair of bone, cartilage or other connective tissue comprising: generating a first electrical signal having a first repeating pattern of a number of pulse bursts, each of the pulse bursts comprising a plurality of individual positive pulses of a first voltage level L 1 of a first duration T 1 , the individual positive pulses separated by a number of negative pulses of a second duration T 2 at a second voltage level L 2 , wherein each of the pulse bursts has a third duration T 3 and are separated from each other at least by an equalizing pulse of a fourth period T 4 at the second voltage level L 2 ; wherein the first duration T 1 equals 13 msec, the second duration T 2 equals 200 μsec, and the third duration T 3 equals 1 sec; and applying the generated first electrical signal to the bone, cartilage, or other connective tissue to modulate development or repair of the tissue.
