摘要： A pacemaker having a fault-tolerant elective replacement indicator (ERI) triggering scheme in which transient excursions of parameters used as criteria for triggering ERI are rejected as triggering events. Periodic assessments of certain indicia of battery depletion are made, and subjected to a long-term low-pass filtering operation in order to reduce the effects of transient excursions of the indicia which result from non-ERI conditions. Over a long period of time (e.g., a day) predetermined threshold values of the indicia of interest must be exceeded a predetermined number of times in order for the device to issue an ERI. In one disclosed embodiment of the invention, the battery's loaded terminal voltage and internal impedance are used as indicators of the battery's depletion level. Periodically, these values are measured and converted to digital values. The digital values are subjected to a low-pass filtering operation to prevent temporary or transient excursions of the impedance and voltage curves from causing ERI to be triggered. In another disclosed embodiment of the invention, a long term fading average of periodically measured values is maintained. When the measured values are found to fulfill the ERI criteria, assessment of the parameters of interest is performed at an increased rate. While assessments are performed at the increased rate, the continuously updated fading average value must fulfill the ERI triggering criteria at least a predetermined number of times before ERI is triggered. If the fading average fails to fulfill the ERI triggering criteria the required number of times, assessments are resumed at the first, slower periodic rate.

摘要： Capacitor packaging according to the disclosure provides advantages particularly in connection to compact and/or complex-shaped medical devices (e.g., having limited interior volume defined by domed and/or irregular exterior surfaces). In addition, capacitors of the type shown and described herein can be utilized in relatively compact external defibrillators, such as automatic external defibrillators or clinician-grade, automated or manually-operated external defibrillators. In one form a plurality of capacitors having substantially flat exterior surfaces are placed in an abutting relationship between at least a pair of major surfaces and the major surfaces are spaced from an opposing or adjacent surface in a non-parallel configuration. In other forms, one or more exterior surface portions have a common and/or complex radius dimension (i.e., the surfaces are curved).

摘要： Power source longevity monitor for an implantable medical device. An energy counter counts the amount of energy used by the implantable medical device. An energy converter converts the energy used into an estimate of remaining power source longevity and generating an energy longevity estimate. A voltage monitor monitors the voltage of the power source. A voltage converter converts the voltage monitored by the voltage monitor into an estimate of remaining longevity of the power source and generating a voltage longevity estimate. A calculator is operatively coupled to the energy converter and to the voltage converter and predicts the power source longevity using the energy longevity estimate early in the useful life of the power source and using the voltage longevity estimate later in the useful life of the power source.

摘要： 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.
