摘要： A method, system, and apparatus for performing a lead condition assessment and/or a lead orientation determination associated with an implantable medical device (IMD). A first impedance is determined. The first impedance relates to the impedance relative to a first electrode and a portion of the IMD. A second impedance is determined. The second impedance relates to the impedance relative to a second electrode and the portion of the IMD. The first impedance is compared with the second impedance to determine an impedance difference. A determination is made whether the impedance difference is outside a predetermined tolerance range. Furthermore, artifact measured during impedance measurements or test pulses may be compared to assess lead orientation. An indication of a lead condition error is provided in response to determining that the impedance difference is outside the predetermined tolerance range.

摘要： Methods and systems for constructing a comprehensive history for an IMD are disclosed. The method includes interrogating an implantable medical device (IMD) with an interrogating external programmer device (EPD), and comparing a unique signature associated with the interrogating EPD to a stored signature, associated with a particular programmer device that most immediately previously programmed the IMD, in memory of the IMD. If the unique signature of the interrogating programmer device is not the same as the stored signature, the method includes recording the stored signature in the interrogating EPD. The method may optionally include replacing the stored signature in the IMD memory with the unique signature of the interrogating EPD if the interrogating EPD programs the IMD. A comprehensive history for the IMD may be constructed by tracing the values in the IMD and the programmer databases.

摘要： A method and an apparatus for determining a time period remaining in a useful life of an energy storage device in an implantable medical device. The method may include measuring a voltage of the energy storage device to produce a measured voltage, and comparing the measured voltage to a transition voltage. While the measured voltage is greater than or equal to the transition voltage, the time period remaining in the energy storage device's useful life is approximated based upon a function of charge depleted. While the measured voltage is less than the transition voltage, the time period remaining in the energy storage device's useful life is approximated based upon a higher order polynomial function of the measured voltage. The transition voltage corresponds to a predetermined point on a energy storage device voltage depletion curve representing the voltage across the energy storage device over time.

摘要： An implantable medical device (IMD) may include a lead circuit including a first node configured to be coupled to a first lead that may be coupled to a first target tissue and including a second node configured to be coupled to a second lead that may be coupled to a second target tissue. The IMD may include an impedance unit that may determine at least one characteristic of coupled energy associated with the lead circuit, where the coupled energy may be produced by a source external to the IMD. The impedance unit may provide an impedance between the first node and the second node, where the impedance is selected based at least in part on a characteristic of the coupled energy. The impedance is selected to reduce the coupled energy or a negative effect associated with functionality of the IMD induced by the coupled energy.

摘要： A method and an apparatus for projecting an end of service (EOS) and/or an elective replacement indication (ERI) of a component in an implantable device is provided. The method comprises measuring the measured voltage of the energy storage device, and determining whether the measured voltage is less than a transition voltage. When the measured voltage is less than the transition voltage, determining a time period remaining until an end of service of the energy storage device is based upon a function of the measured voltage. When the measured voltage is greater than or equal to the transition voltage, determining a time period remaining until an end of service of the energy storage device is based upon a function of the total charge depleted. The transition voltage is a voltage associated with the transition point of non-linearity in the battery voltage depletion curve.
