Patent ID: 7747328

Claim:
A method of treating a wound on a limb, comprising: positioning a plurality of electrodes spaced apart in the region of the wound on the limb; reducing pooling of blood in the region of the wound by wrapping a compression bandage around the limb and over the electrodes and the region of the wound; and applying a sequence of current waveforms between the electrodes, wherein applying the sequence of current waveforms comprises: reducing the resistance of the wound by applying a first waveform comprising a series of current pulses having an amplitude in a range of from 80 to 300 μA, having a frequency in a range from 0.5 to 1.5 pulses per second and a pulse width in a range from 333 to 1000 ms; applying a second waveform comprising a series of current pulses having an amplitude in a range of from 20 to 60 μA, having a frequency in a range from 2 to 4 pulses per second and a pulse width in a range from 125 to 250 ms; and applying a third waveform comprising a series of current pulses having an amplitude in a range of from 250 to 640 μA, having a frequency in a range of from 80 to 120 pulses per second and a pulse width in a range from 4 to 6 ms.
