Claim 18:
19. A method comprising:
in operation of a defibrillator including a defibrillator body that includes a handle, a trigger and a surface, and a pair of electrodes transversely disposed on the surface, wherein the pair of electrodes are in fixed operative connection with the body, and wherein 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 the handle of the defibrillator body, imparting an impact hammer strike to the piezoelectric crystal located within the handle,
b) responsive at least in part to the impact hammer strike, producing an electrical potential between the pair of disposed apart externally accessible electrodes that are in fixed operative connection with a surface of the body,
whereby the electrical potential enables delivering an electrical shock to heart muscles of a patient through engagement of the electrodes with a chest of the patient.
