    Abstract: Deep brain electrodes are remotely sensed and activated by means of a remote active implantable medical device (AIMD). In a preferred form, a pulse generator is implanted in the pectoral region and includes a hermetic seal through which protrudes a conductive leadwire which provides an external antenna for transmission and reception of radio frequency (RF) pulses. One or more deep brain electrode modules are constructed and placed which can transmit and receive RF energy from the pulse generator. An RF telemetry link is established between the implanted pulse generator and the deep brain electrode assemblies. The satellite modules are configured for generating pacing pulses for a variety of disease conditions, including epileptic seizures, Turrets Syndrome, Parkinson's Tremor, and a variety of other neurological or brain disorders.

    Abstract: An RFID tag interrogator is described. The interrogator comprises a time-out circuit and an actuatable RF signal generator for transmitting an electromagnetic signal. Upon first actuation, the RF signal generator transmits a first electromagnetic signal having a first limited total continuous transmit time that is no longer than a predetermined transmit-time. That transmission is followed by an interim period of a defined length where the time-out circuit renders the interrogator incapable of transmitting the electromagnetic signal. The interim period is followed by the RF signal generator transmitting a second electromagnetic signal having a second limited total continuous transmit time that is no longer than the predetermined transmit time. The time-out circuit prevents the first, second and subsequent transmissions of the electromagnetic signal that are each no longer than the predetermined transmit time after a prior electromagnetic signal has been transmitted until the interim period has expired.

    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).
