    Abstract: A feedthrough filter capacitor assembly comprising a terminal pin connector is described. The terminal pin connector is designed to facilitate an electrical connection between the terminal pin comprising a multitude of compositions to a circuit board of an implantable medical device. The terminal pin connector comprises a clip portion positioned within a connector housing. The connector clip mechanically attaches to the terminal pin of the feedthrough with at least one prong and an exterior surface of the connector housing electrically contacts the circuit board, creating an electrical connection therebetween. The connector housing comprises a material that is conducive to a weld or solder attachment process to the circuit board. The feedthrough filter capacitor assembly is particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.

    Abstract: An AIMD includes a conductive housing, an electrically conductive ferrule with an insulator hermetically sealing the ferrule opening. A conductive pathway is hermetically sealed and disposed through the insulator. A filter capacitor is disposed within the housing and has a dielectric body supporting at least two active and two ground electrode plates interleaved, wherein the at least two active electrode plates are electrically connected to the conductive pathway on the device side, and the at least two ground electrode plates are electrically coupled to either the ferrule and/or the conductive housing. The dielectric body has a dielectric constant less than 1000 and a capacitance of between 10 and 20,000 picofarads. The filter capacitor is configured for EMI filtering of MRI high RF pulsed power by a low ESR, wherein the ESR of the filter capacitor at an MRI RF pulsed frequency or range of frequencies is less than 2.0 ohms.

    Abstract: A circuit board for an active implantable medical device (AIMD) has a circuit board land connected to at least one electrical circuit. A hermetic feedthrough terminal pin connector for the AIMD includes an electrical insulator hermetically sealed to an opening of an electrically conductive ferrule. A terminal pin of the feedthrough extends outwardly beyond the insulator. A terminal pin connector has an electrically conductive connector housing that is connected to the circuit board land by an electrical connection material. At least one electrically conductive prong supported by the connector housing contacts and compresses against the feedthrough terminal pin to thereby make a removable electrical connection between the circuit board and the terminal pin. An insulative material loaded with electrically insulative nanoparticles coats at least a portion of the sidewall of the connector housing and the electrical connection material connecting the connector housing to the circuit board land.

    Abstract: An enhanced RF switchable filtered feedthrough for real-time identification of the electrical and physical integrity of an implanted AIMD lead includes a DOUBLE POLE RF switch disposed on the device side. Additionally, the RF switchable filtered feedthrough can optionally include transient voltage suppressors (TVS) and an MRI mode. In an embodiment, a DOUBLE POLE RF switch selectively disconnects EMI filter capacitors so that an RF test/interrogation signal is sent from the AIMD down into an implanted lead(s). The reflected RF signal is then analyzed to assess implanted lead integrity including lead body anomalies, lead insulation defects, and/or lead conductor defects. The Double Pole switch is configured to be controlled by an AIMD control signal to switch between FIRST and SECOND THROW positions. In the FIRST THROW position a conductive leadwire hermetically sealed to and disposed through an insulator is electrically connected to a filter capacitor, which is then electrically connected to the ferrule of a hermetic feedthrough of an AIMD. In the FIRST THROW position, EMI energy imparted to a body fluid side implanted lead can be diverted to the housing of the AIMD. In the SECOND THROW position the conductive leadwire is electrically connected to an RF source disposed on the device side of the housing of the AIMD. While in the SECOND THROW position, a reflective return signal from the RF source is measured and analyzed to determine if the implanted AIMD lead exhibits any life-threatening performance issues, such as lead body anomalies, lead insulation defects or changes, or even defective, fractured or dislodged lead conductors. In another embodiment, a SINGLE POLE RF switch is configured to disconnect filter capacitors during the delivery of a high-voltage cardioversion shock from an implantable cardioverter defibrillator. Dis-connection of the filter capacitor either reduces or eliminates filter capacitor pulse inrush currents, which allows for the use of standard low-voltage filter capacitors instead of larger and more expensive high-voltage pulse rated filter capacitors. Dis-connection of the filter capacitor also allows for an RF interrogation pulse to be applied to the implanted lead in real-time (for example, pre-set intervals throughout the day).
