Abstract
An implantable medical device (IMD) includes a distributed core, step-up transformer that is arranged within a hermetically sealed housing in space that would otherwise not be occupied and in a way that minimizes the size and weight of the IMD. The IMD preferably comprises an implantable cardioverter-defibrillator (ICD) of the type having a battery power source, a capacitor bank for storing a charge from the battery, and electronic circuitry coupled to the battery power supply and the capacitor bank for charging the capacitor bank through a step-up transformer and for discharging the capacitor bank into or around a patient's heart. The step up transformer comprises a plurality of distributed core step-up transformer modules which are miniaturized sufficiently to fit within small spaces of the housing cavity. The plurality of distributed core, step-up transformer modules are amenable to being arranged to fit into spaces within the cavity of the IMD housing that are not otherwise occupied. The space otherwise occupied by the bulky, prior art step-up transformer can than be occupied by other components or can result in making the housing itself smaller and possibly thinner in profile than it would otherwise be.
