International ClassA61N 001/00AbstractA noninvasive apparatus for treating living tissue and cells by means of a pulsed electromagnetic field, and particularly suitable for bone growth stimulation. A treatment coil is noninvasively mounted in proximity to an afflicted body part to be treated, and an electronic generator coupled to said treatment coil generates pulses having a positive pulse portion 200 to 250 microseconds in duration and a negative pulse portion having a duration less than approximately 50 microseconds, the pulses further characterized by a smooth transition at least from the leading edge to a relatively flat top segment. High-frequency content is substantially reduced, particularly at frequencies above 200 kHz.Other References
