International Classification:

A61N 1/00

US Classification:

607 2

Abstract:

A method of reforming a wet-tantalum capacitor includes providing a medical device comprising a wet-tantalum capacitor. The capacitor has a rated voltage and including a hydrated anodic deposit. The method further includes charging the capacitor to a voltage that is less than approximately seventy-five percent of the rated voltage and at least partially discharging the capacitor after the charging step. The charging step is performed at a sufficient voltage to dehydrate the anodic deposit while not significantly decreasing the service life of the capacitor.
