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: One or more inductors and one or more capacitors are physically disposed relative to one another in series and are electrically connected to one another in parallel to form a bandstop filter. Chip inductors and chip capacitors having spaced apart conductive terminals are physically arranged in end-to-end abutting relation to minimize electrical potential between adjacent conductive terminals. The bandstop filter may be hermetically sealed within a biocompatible container for use with an implantable lead or electrode of a medical device. The values of the inductors and the capacitors are selected such that the bandstop filter is resonant at one or more selected frequencies, such as an MRI pulsed frequency.

Abstract: A non-hermetically sealed and biocompatible multi-turn RFID loop antenna is electrically connected to a RFID chip which is enclosed within its own hermetically sealed miniature container. The hermetic seal can be very small and the loop antenna can be relatively large, wherein the entire package is both highly reliable, resistant to body fluids and completely biocompatible. The RFID structure can be implanted in a patient and later communicate with an RFID interrogator to provide information relating to the patient and/or implantable medical devices.

Abstract: Decoupling circuits are provided which transfer energy induced from an MRI pulsed RF field to an energy dissipating surface. This is accomplished through broadband filtering or by resonant filtering. In a passive component network for an implantable leadwire of an active implantable medical device, a frequency selective energy diversion circuit is provided for diverting high-frequency energy away from a leadwire electrode to a point or an area spaced from the electrode, for dissipation of high-frequency energy.

Abstract: An EMI filter capacitor assembly utilizes biocompatible and non-migratable materials to adapt electronic components for direct body fluid exposure. The assembly includes a capacitor having first and second sets of electrode plates which are constructed of non-migratable biocompatible material. A conductive hermetic terminal of non-migratable and biocompatible material adjacent to the capacitor is conductively coupled to the second set of electrode plates. One or more conductive terminal pins having at least an outer surface of non-migratable and biocompatible material are conductively coupled to the first set of electrode plates, while extending through the hermetic terminal in non-conductive relation. The terminal pins may be in direct contact with the first set of electrode plates, or in contact with a termination surface of conductive connection material. The termination surface is also constructed of non-migratable and biocompatible materials. Layers of glass may be disposed over surfaces of the assembly, including the capacitor.
