Abstract
A non-invasive, portable electromagnetic therapeutic method and apparatus for promoting the healing of damaged or diseased living tissue including fractured bone and in particular nonunion or delayed union bone fractures are described. The method and apparatus involve generating a signal having a series of substantially symmetric voltage cycles of bursted pulses having narrow pulse widths on the order of 0.5 to 20 microseconds and converting the signal into an electromagnetic field which extends into an area for desired tissue healing. The portable noninvasive apparatus can be readily worn or carried by a patient and is capable of generating an energy-efficient symmetrical signal coacting with a coil for transducing the signal into electromagnetic pulses.
