High-power pulsed electromagnetic field applicator system

A high-power pulsed electromagnetic field (PEMF) applicator system, the system comprising:

• a base housing comprising a controller configured to generate a low-power control signal, wherein the controller is configured to include an applicator address in the low-power control signal;
• and
• a plurality of applicators coupled to the base, each applicator comprising:
• a generator configured to receive the low-power control signal, decode the applicator address, and to produce, when the applicator address matches an identifying code corresponding to the applicator, a high-power, pulsed electromagnetic field signal based on the low-power control signal, wherein the high-power pulsed electromagnetic field signal has a power of greater than 40 W;
• a coil circuit configured to emit the high-power pulsed electromagnetic field signal;
• and
• an electromagnetic energy shield disposed between the generator and the coil circuit.

A high-power pulsed electromagnetic field (PEMF) applicator comprising:

• a drive circuitry configured to receive a low-power control signal from a controller, wherein the drive circuitry comprises a generator configured to generate high-power pulsed electromagnetic field signal having a power of 40 W or greater based on the low-power control signal;
• a coil circuit configured to apply the high-power pulsed electromagnetic field signal to a subject;
• an electromagnetic energy shield disposed over the drive circuitry;
• and
• a detector configured to detect a field strength of the high-power pulsed electromagnetic field signal applied by the coil circuit,
• wherein the detector is configured to transmit the field strength to the controller so that the controller can adjust the low-power control signal in response to the detected field strength.

A method for treating a patient with high-power pulsed electromagnetic fields, the method comprising:

• providing a low-power control signal including a gating code from a controller in a base housing:
• transmitting the low-power control signal to at least one hand-held applicator in communication with the base housing;
• generating, in the hand-held applicator, a high-power, pulsed electromagnetic field signal based on the low-power control signal when the gating code matches an identifier code for the hand-held applicator;
• emitting the high-power, pulsed electromagnetic field signal from a coil in the at least one applicator;
• and
• detecting the emitted high-power, pulsed electromagnetic field signal using a detector that is coupled to an opposite side of the coil in the hand-held applicator.
