Abstract:

An osteo or tissue healing device, kit and method of using the device to promote healing of compromised bone or tissue in a living mammal is disclosed. The osteo or tissue healing device includes a magnetic field emitter and a controlling circuit. The magnetic field emitter of the device is electrically coupled to a controlling circuit in which the magnetic field emitter is configured to provide a time variant magnetic field when driven by an electric pulse train from the controlling circuit in such a manner that the time variant magnetic field results in a magnetic (B) field exhibiting a magnetic slew rate of at least about 10 kiloGauss/sec. The controlling circuit of the device is electrically coupled to the magnetic field emitter and is configured to be powered by a power source, in which the controlling circuit is configured to output the electric pulse train driving the magnetic field emitter. It is thought that the steep magnetic field pulses and the relatively long inactive periods play important roles in promoting bone or tissue healing processes. The kit includes the unassembled components of the device. The method of using the osteo or tissue healing device includes the step of applying a time variant magnetic field to bone or tissue to promote healing of the bone or tissue.
