Abstract (en)
[origin: WO9622811A1] A staged energy storage system (40) provides electrical energy to an implantable cardioverter defibrillator device by using the combination of a first stage energy source (45), and a second stage energy concentration system (50). The second stage energy concentration system (50) allows for either a lower density and/or lower voltage energy source to be used as the first stage energy source (45), thereby decreasing the battery cost, size and weight, or alternatively, for multiple closely spaced countershock pulses to be delivered. In one embodiment, the second stage energy concentration system (50) comprises a rechargeable battery (50). In another embodiment, the second stage energy capacitor system (50) comprises a high energy density capacitor system.
