Abstract: A self-centering washer is positioned between the feedthrough and filter capacitor of a filtered feedthrough. The washer has openings through which first and second terminal pins extend. A first opening has an inner arcuate portion contacting the first terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. A second opening has an inner arcuate portion contacting the second terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. In an imaginary configuration with the first and second washer openings superimposed one on top of the other, the cumulative arcuate distance of the inner arcuate portions about one of the terminal pins, subtracting overlap, results in a gap between the superimposed washer openings that is less than a diameter of the first and second terminal pins so that the washer is prevented from lateral movement.

Abstract: The high-voltage and/or high-frequency pulse dielectric breakdown strength (DBS) of an implantable medical device is increased by strategically positioning insulation materials on or adjacent to the external surfaces of a filter capacitor. Dielectric breakdown strength is further increased by adding polymeric or ceramic nanoscale metal oxide insulative powders to the insulation materials.

Abstract: A shipping container system comprises a bottom panel, a plurality of side panels, and a top panel, each with interlocking features. The side panels interlock with the bottom panel to assemble a self-supporting shipping container. A plurality of horizontally oriented slots are formed in an opposing pair of the side panels, and arranged at different heights between the bottom panel and a top edge of the side panels. A cross member is positioned at a selected height by insertion into an opposing pair of the slots, in order to restrain one or more shipping units against vertical motion inside the shipping container. The top panel interlocks with the side panels to cover the shipping container, and is spaced above the plurality of shipping units at a clearance maintained by the cross member.
