  • Publication number: 20050004618
    Abstract: An implantable medical device (IMD) including a nonhermetic battery is described. The IMD includes components and a power source module that includes the nonhermetic battery. The IMD also includes a barrier to substantially impede movement of substances from the nonhermetic battery to the components. The barrier may include a hermetic feedthrough, a gel, a polymer, or a solid electrolyte within the nonhermetic battery, and a seal member. The barrier may also be a material that encapsulates the nonhermetic battery and a getter within the IMD. In some embodiments, the IMD comprises a modular IMD including an interconnect member. In that case, the barrier may include a material that fills at least a portion of a void defined by the interconnect member. A length and a cross-sectional area of the interconnect member may also act as a barrier.

  • Publication number: 20050003268
    Abstract: The invention is directed to techniques for decreasing the volume and thickness of a hermetic battery that includes an electrode stack contained within a hermetic housing. In particular, the invention is directed to batteries that have a non-uniform thickness as defined by the hermetic housing. A battery according to the invention includes a battery housing with at least two battery housing portions that define different thicknesses. For example, a first portion of the battery housing may have first thickness and house the battery, while a second portion of the battery housing has a second thickness and includes one or more feedthroughs. The second thickness may be greater than the first thickness.

  • Publication number: 20020099590
    Abstract: A business management method integrates a complex, long cycle business into a common, concise format and set of order fulfillment metrics that provide clear status as well as predictive indicators of issues across all functional areas to all levels of management throughout an organization. The uniformity of the approach across all business functions allows for a standard comparison of the fulfillment risks and status across the entire business. The business management method utilizes statistical analysis, variation based metrics, mean based metrics, line rate analysis indicators and key quality indicators to facilitate proactive actions at the senior management level before issues become systemic and/or impact a company's ability to timely deliver products to its customers.
