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.

摘要： An implantable medical device having a dual cell power source powering a high-power output circuit and a low-power control circuit. The power source includes a first, high-rate cell and a second, lower-rate cell having a rate capability less than a rate capability of the first, high-rate cell. The first and second cells are electrically connected to the output circuit and control circuit by circuitry. In one embodiment, the circuitry connects the first and second cells in parallel to the output circuit and the control circuit, and includes a switching circuit for selectively uncoupling the first, high-rate cell from the control circuit during a transient high power pulse. In another embodiment, the first and second cells are formed within a single case and are connected in parallel to the output circuit and the control circuit. In another embodiment, the high-rate cell is anode limited, characterized by a rate capability exhibiting minimal dependence on time up to a pre-selected voltage-based ERI at which at least 40 percent of the cathode is consumed.

摘要： The present teachings include an electrochemical cell including an anode, a cathode, an electrolyte, a separator disposed between the cathode and anode, and a housing containing the anode, cathode, electrolyte, and separator. The separator can include a first sheet consisting essentially of a single layer material and a second sheet distinct from the first sheet. The second sheet can include an inner microporous layer laminated between two more outer layers. In some cells, the inner layer can have a transition temperature between a porous configuration and a substantially non-porous configuration that is between about 80 degrees C and 150 degrees C, and in which the two more outer layers maintain their structural integrity to at least about 10 degrees C greater than the first layer transition temperature.
