Claim 0:
1. A method comprising:
in operation of a defibrillator including a body having a handle and a surface, and a pair of electrodes disposed on the surface, wherein the pair of electrodes are in fixed operative connection with the body, and each of the electrodes is externally accessible on the body, and wherein a trigger, a hammer and a circuit extend within the handle and the circuit includes a piezoelectric crystal,
a) responsive at least in part to movement of the trigger on ah handle of thia body of the defibrillator, causing the hammer that is movably mounted relative to the body to impart an impact strike to the piezoelectric crystal of the circuit within the handle,
b) responsive at least in part to the impact strike, causing an electrical potential between the pair of disposed externally accessible electrodes that are in operative connection with the circuit and in fixed operative connection with the surface of the body,
wherein the electrical potential between the electrodes is sufficient to provide an electrical shock to heart muscles of a patient through the pair of electrodes when the electrodes are in direct engagement with the chest of the patient.
