A capacitor assembly extends between the inner and outer electrode and serves to bypass relatively high frequency signals carried by the inner electrode to the grounded outer electrode. The capacitor assembly includes a plurality of monolithic multilayer ceramic capacitors, each capacitor having first and second terminals that are respectively surface mounted onto inner and outer concentric conductive rings. A plurality of deflectable tines project radially inward from the inner ring and resiliently circumferentially contact the exterior of the inner electrode. Similarly, a plurality of deflectable tines project radially outward from the outer ring and resiliently circumferentially contact the interior of the outer electrode.Type: GrantFiled: May 8, 2012Date of Patent: March 18, 2014Inventor: George M. Kauffman

Patent number: 8653384Abstract: A co-fired hermetically sealed feedthrough is attachable to an active implantable medical device. The feedthrough comprises an alumina dielectric substrate comprising at least 96 or 99% alumina. A via hole is disposed through the alumina dielectric substrate from a body fluid side to a device side. A substantially closed pore, fritless and substantially pure platinum fill is disposed within the via hole forming a platinum filled via electrically conductive between the body fluid side and the device side. A hermetic seal is between the platinum fill and the alumina dielectric substrate, wherein the hermetic seal comprises a tortuous and mutually conformal interface between the alumina dielectric substrate and the platinum fill.Type: GrantFiled: January 16, 2013Date of Patent: February 18, 2014Assignee: Greatbatch Ltd.Inventors: Xiaohong Tang, William C.
