Patent number: 8849403Abstract: A lead extending exteriorly from an active implantable medical device (AIMD) is at least partially ensheathed within an electromagnetic interference (EMI) shield. The AIMD has a conductive equipotential surface to which the EMI shield may be conductively coupled. An impeding circuit may be provided for raising the high frequency impedance of the lead. An energy diversion circuit may also be provided for conductively coupling the lead to the EMI shield.Type: GrantFiled: May 26, 2010Date of Patent: September 30, 2014Assignee: Greatbatch Ltd.Inventors: Robert Shawn Johnson, Robert A. Stevenson, Warren S. Dabney, Holly Noelle Moschiano, Kishore Kumar Kondabatni, Neal Nesselbeck, Joseph Spaulding, Henry R. Halperin, Albert C. Lardo

Patent number: 8313621Abstract: A method and apparatus for anodizing a porous valve metal pellet in a flowing liquid electrolyte is described. The apparatus comprises an insulative container comprised of a lower region, a central region including a cavity for holding the pellet, an upper region, and a continuous passageway extending through the lower, central, and upper regions. Lower and upper screens serving as lower and upper electrodes are disposed in the passageway in the lower and upper container regions, respectively. During anodizing, the electrolyte flows through the lower container region including the lower screen, the porous pellet and then the upper container region including the upper screen. The lower and upper screens are at an opposite electrical polarity as the pellet so that a dielectric oxide is formed on the exposed valve metal including interior portions of the pellet that are exposed to the flowing electrolyte.Type: GrantFiled: January 28, 2011Date of Patent: November 20, 2012Assignee: Greatbatch Ltd.Inventors: David Goad, Neal Nesselbeck, Jason Hahl

Patent number: 7727372Abstract: A method for anodizing valve metal structures to a target formation voltage is described. The valve metal structures are placed in an anodizing electrolyte and connected to a power supply that generates a source voltage to at least one current limiting device. If at least two current limiting devices are used, they are in series with the valve metal structures with the one current limiting device connected to at least one structure. The valve metal structures are then subjected to a current that decreases over time, a formation voltage that increases over time to a level below the voltage from the power supply and a power level that is self-adjusted to a level that decreases excessive heating in the structure. The invention also includes the components for the method.Type: GrantFiled: December 5, 2005Date of Patent: June 1, 2010Assignee: Greatbatch Ltd.Inventors: Yanming Liu, Neal Nesselbeck, David Goad, Barry Muffoletto

Patent number: 7271994Abstract: An electrical energy storage device such as a wet tantalum electrolytic capacitor or an electrochemical cell such as a lithium/silver vanadium oxide cell is described. The enclosure comprises a drawn casing portion having a planar face wall supporting a surrounding sidewall and is shaped to nest the anode, cathode and intermediate separator components. A mating cover is a stamped planar piece of similar material having a periphery edge welded to the edge of the casing portion surrounding sidewall. In order to prevent heat generated during the welding process from damaging the separator, the anode portion adjacent to the weld site is contoured. This provides sufficient space between the weld and the separator supported on the anode at the contour so that what heat is transmitted to the separator by convection and conduction mechanism will not damage the separator.Type: GrantFiled: June 7, 2006Date of Patent: September 18, 2007Assignee: Greatbatch Ltd.Inventors: Eric Stemen, Troy Lindke, Edward Gloss, Rodney Stringham, Neal Nesselbeck, Joseph Spaulding, Barry Muffoletto, Doug Eberhard
