Abstract: An energy management system facilitates the transfer of high frequency energy coupled into an implanted abandoned lead at a selected RF frequency or frequency band, to an energy dissipating surface. This is accomplished by conductively coupling the implanted abandoned lead to the energy dissipating surface of an abandoned lead cap through an energy diversion circuit including one or more passive electronic network components whose impedance characteristics are at least partially tuned to the implanted abandoned lead's impedance characteristics.

Abstract: A lead body adapted for in-vivo implantation in a living subject includes a proximal end configured for electrical and mechanical connection to a therapy or a monitoring device, and a distal end. A collar is disposed at the distal end of the lead body, and a casing is disposed within the collar and is translatable along a central longitudinal axis of the collar. At least one electrical conductor extends substantially the length of the lead body, and an electronic component is disposed within the casing and conductively coupled to the electrical conductor. An electrode is mechanically connected to the casing and conductively coupled to the electronic component. A seal is disposed between the casing assembly and the collar to prevent passage of ionic fluid into the lead body through its distal end.

Abstract: A feedthrough terminal assembly for an active implantable medical device (AIMD) includes a conductive terminal pin or lead wire which extends through a conductive ground plane of the AIMD in non-conductive relation. A feedthrough capacitor associated with the terminal pin or lead wire has first and second sets of electrode plates coupled, respectively, to the conductive pin or lead wire and to the ground plane. A breathable electromechanical connection material conductively couples the capacitor's electrode plates to respective components of the AIMD, which allows helium gas to pass freely therethrough during a standard pressurized or vacuum pull helium leak detection test. A breathable washer may be disposed between an alumina insulator and a surface of the capacitor. An additional further breathable coating or conformal coating may be placed over a surface of the feedthrough capacitor disposed toward the interior of the AIMD.

Abstract: A band stop filter is provided for a lead wire of an active medical device (AMD). The band stop filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the band stop filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the band stop filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the band stop filter is integrated into a TIP and/or RING electrode for an active implantable medical device.

Abstract: A telemetry wake-up circuit is electrically disposed between a telemetry transceiver associated with an AIMD, and an RF tag. The RF tag may be remotely interrogated to generate a signal to which the telemetry wake-up circuit is responsive to switch the telemetry transceiver from a sleep mode to an active telemetry mode. In the sleep mode, the telemetry transceiver draws less than 25,000 nanoamperes from the AIMD, and preferably less than 500 nanoamperes.

Abstract: An EMI filtered terminal assembly includes at least one conductive terminal pin, a feedthrough capacitor, and a counter-bore associated with a passageway through the capacitor and the lead wire. Preferably, the feedthrough capacitor having counter-drilled holes on its top side is first bonded to a hermetic insulator. The counter-bore in the capacitor provides greater volume for the electro-mechanical attachment between the capacitor and the lead wire, permitting robotic dispensing of, for example, thermal-setting conductive adhesive.

Abstract: A one-piece cylindrical bandstop filter for medical lead systems incorporates parallel capacitive and inductive elements in a compact cylindrical configuration. The compact cylindrical configuration of the bandstop filter does not add significantly to the size or weight of the medical lead system. Preferably, the bandstop filters are of biocompatible materials or hermetically sealed in biocompatible containers. The parallel capacitive and inductive elements are placed in series with the medical lead system, and are selected so as to resonate at one or more selected frequencies, typically MRI pulsed frequencies.
