    摘要： A capacitor structure comprises a shallow drawn case having a first major side and a peripheral wall extending therefrom, the first major side having a first interior surface and the wall having a peripheral interior surface. A lid is sealingly coupled to the case along adjacent edges of the lid and the wall, the lid and said case forming an encasement of the capacitor structure, the lid comprising a second interior surface. A cathode material is disposed proximate the first and second interior surfaces, and an anode is positioned intermediate the cathode material and has a peripheral portion positioned proximate the adjacent edges. A protective layer on the peripheral portion protects the anode during the sealing process. A first insulative separator is positioned between the anode and the cathode material.

    摘要： A high voltage capacitor anode for an implantable medical device is fabricated by sintering, anodizing and heat treating a pressed tantalum powder slug. The sintering may be performed at a temperature between approximately 1500° C. and approximately 1600° C. for a time between approximately 3 minutes and approximately 35 minutes; subsequent anodization may be performed by immersing the slug in an electrolyte at a temperature between approximately 15° C. and approximately 30° C. and then applying a voltage across the slug, the voltage being between approximately 175 Volts and approximately 375 Volts; subsequent heat treating may be performed at a temperature between approximately 400° C. and approximately 460° C. for a time between approximately 50 minutes and approximately 65 minutes. Following heat treating, the anode is reformed by a second anodization.

    摘要： The present invention generally relates to improved capacitors; in particular, the present invention provides advanced valve metal (AVM) anodes and methods for fabricating AVM anodes having complex surface and interior features for use in high energy density capacitors. Such anodes find use in high voltage capacitors incorporated into implantable medical devices (IMDs), among other uses. The AVM anodes may be pressed into virtually any arbitrary shape and may have a gradually changing (or substantially constant) density profile throughout the AVM anode. Such AVM anodes may also be perforated or shaped to receive one or more cathode members. The AVM anodes enhance packaging efficiency for compact high energy density capacitors.

    摘要： A method and apparatus exercise a battery of an implantable medical device by determining whether a film is disposed on a portion of an electrode of a battery, discharging the battery a sufficient amount to reduce the film, and optimizing energy used during exercising the battery. The apparatus includes a battery having an electrode that develops a resistive film and a low deformation rate capacitor capable of storing a charge from the battery, the capacitor requiring few or no periodic discharges of the battery for reformation. The energy from the battery is periodically discharged into the low deformation-rate capacitor to reduce film buildup on the electrode.
