A capacitor for use in implantable medical devices (IMDs) such as
implantable defibrillators, implantable cardioverter-defibrillators,
implantable pacemaker-cardioverter-defibrillators, and the like stores
charge for use in the delivery of high voltage electrical therapy. The
capacitor design can reduce capacitor volume significantly and may also
improve charge holding capacity relative to conventional capacitor
designs. Moreover, since capacitors typically comprise a significant
portion of the volume of an IMD, significant reductions in capacitor
volume can likewise significantly reduce the size of the IMD.
