First Claim
Patent Images
1. An implantable cardiac defibrillator comprising:
- an outer housing defining a chamber;
an energy source within the outer housing;
a capacitor within the housing;
the capacitor comprising a capacitor housing and a plurality of flat, stacked, charge storing layers within the chamber;
the layers each including at least first and second sheets separated from each other by a separator sheet positioned therebetween;
the layers each having a periphery; and
the periphery of each layer having a minor portion comprising at least one alignment element, and wherein the second sheet extends beyond the first sheet at the alignment element.

Abstract
A capacitor for an implantable cardiac defibrillator with a housing defining a chamber. A plurality of flat, stacked, charge storing layers reside within the chamber. Each of the layers includes at least a first and a second electrically conductive sheets separated by a sheet in between. The first sheet is electrically connected to the housing, and the second sheet is electrically isolated from the housing. The layers each have a periphery having at least one alignment element, with the second sheet extending to the periphery along at least a portion of the alignment element, such that the layers may be engaged at the alignment element to register the layers during assembly.
