ABSTRACT:
The present invention provides a method for reforming a capacitor of an implantable medical device, such as an implantable cardioverter defibrillator, wherein the capacitor has a nominal voltage. The method of reforming the capacitor comprises charging the capacitor to a first voltage that is above the nominal voltage of the capacitor, partially discharging the capacitor through system leakage, charging the capacitor to a second voltage that is above the nominal voltage, and discharging the capacitor through system leakage until the charge on the capacitor dissipates. The present invention also provides an implantable medical device having a capacitor reforming circuit for reforming the capacitor. Capacitors reformed according to the present invention have reduced charge time deformation compared to capacitors conventionally reformed at the nominal voltage.
