Claim 15:
16. A method comprising:
in operation of a defibrillator including a body that includes 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 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 relative to the handle of the defibrillator body, causing the hammer to impart an impact strike to the piezoelectric crystal within the handle,
b) responsive at least in part to the impact strike, producing an electrical potential between the pair of electrodes in operative electrical connection with the piezoelectrical crystal,
wherein each of the pair of electrodes is disposed from the other electrode on the surface of the body, is in fixed operative connection with the body, and is externally accessible on the body,

whereby the electrical potential between the electrodes, enables delivering an electrical shock to heart muscles of a patient through engagement of the pair of electrodes with a chest of the patient.
