CONTACT-LESS, PORTABLE DEFIBRILLATOR COMPRISING AN ENERGY STORAGE CAPACITOR, A PULSED FIELD COIL, AND PULSE CONTROL CIRCUITRY, TO STIMULATE CARDIAC MUSCLE BY INDUCED VOLTAGE PULSE, INSTEAD OF APPLICATION OF ELECTRODES TO SKIN.

CONTACT-LESS, PORTABLE DEFIBRILLATOR COMPRISING AN ENERGY STORAGE CAPACITOR, A PULSED FIELD COIL, AND PULSE CONTROL CIRCUITRY, TO STIMULATE CARDIAC MUSCLE BY INDUCED VOLTAGE PULSE, INSTEAD OF APPLICATION OF ELECTRODES TO SKIN. INDUCTION COIL WORKS THROUGH CLOTHING, CAN BE APPLIED BY INEXPERIENCED PERSONNEL, AND REDUCES TIME DELAY, PAIN, RISK OF BURNS, TISSUE DAMAGE, OR CARDIAC ARREST. IT MAY ALSO REDUCE THE ENERGY REQUIRED BY ELIMINATING SKIN CONDUCTION LOSSES. PHASE I INCLUDES THE CONSTRUCTION OF AN EXPERIMENTAL PROTO TYPE WITH VARIABLE ENERGY LEVEL, PULSE DURATION, AND PULSE WAVEFORM, FOR THE CONDUCTION OF TESTS TO DETERMINE THE OPTIMUM SPECIFICATIONS FOR A PORTABLE DEVICE. PHASE II INVOLVES THE CONSTRUCTION OF SEVERAL PORTABLE DEVICES FOR CLINICAL AND FIELD TESTING, AND REFINEMENT OF THE DESIGN ON THE BASIS OF RESULTS. PHASE III DEVELOPS A PRODUCTION MODEL.
