ABSTRACT:
A pulsed signal generator for biomedical applications, including electrical stimulation of fracture healing, treatment of osteoporosis, or to strengthen a freshly-healed bone after a cast or other fixation device has been removed. The generator includes dual asymmetric oscillators and associated circuitry to deliver signals efficiently throughout the area to be treated. The components can readily be selected so as to produce any desired output signal, including fixed-magnitude signals and (via suitable voltage-regulating devices) variable-magnitude signals. In addition, the pulse frequency and/or interval can be fixed or adjustable, as may be convenient. In a preferred embodiment of the invention, the generator is powered by readily-available, inexpensive batteries.
