Abstract: A multi-functional, modular PEMF biophysical stimulation field generator device and healing system using small coils and a PEMF technique to create a high magnetic flux penetration into hard and soft tissues for treatment of a variety of conditions, including fractures and osteoporosis, to achieve an anticipated shorter healing and rehabilitation time. The orthogonally-arranged coils are sequentially-activated to develop a rotating cylindrical energy field focussed on a target area so as to stimulate bone growth. An activation signal having a combined waveform is used to activate the coils, comprising a high frequency carrier wave, which is amplitude-modulated, by a low frequency treatment wave for optimal penetration of biological tissue. In a preferred embodiment, a pre-form wrap is provided as a cast, brace or splint, containing small magnetizing coils, with the wrap being placed circumferentially around the body part containing the treatment site.
