Patent attributes
An electrical stimulation apparatus provides an electrical stimulation signal as a DC pulse train at a frequency between 20 kHz and 50 kHz, with the electrical stimulation signal applied to the body of a patient at an injury site, based on sequentially activating respective subsets among a set of electrodes included in an electrode carrier that places the electrodes in contact with the body of the patient. An electrical stimulation method sequentially activates, via an electrical stimulation signal, respective subsets of electrodes among a set of electrodes contacting the body of a patient at an injury site on the body of the patient. Advantageously, in one or more embodiments, the sequential activation follows an activation sequence that “moves” the sources and sinks for the electrical stimulation signal around the injury site, thereby creating spatially distributed signal paths through or across the injury over time.
