Abstract: An inductive charging antenna for charging the power source of an active implantable medical device (AIMD) is described. The charging antenna is supported on the body fluid side of the feedthrough insulator, on the device side of the insulator or it is embedded inside the insulator. The charging antenna is connected to electronic circuits housed inside the medical device to charge the power source so that the device can deliver electrical stimulation to a patient and receive sensed biological signals from body tissue, among other functionalities. If the charging antenna is supported on the insulator body fluid side, it is made from a biocompatible material such as platinum. However, if the charging antenna is embedded inside the feedthrough insulator or is supported on the device side of the insulator, it can be made from a less expensive material that is not biocompatible, for example, copper.

Abstract: A hermetically sealed feedthrough assembly for an active implantable medical device having an oxide-resistant electrical attachment for connection to an EMI filter, an EMI filter circuit board, an AIMD circuit board, or AIMD electronics. The oxide-resistant electrical attachment, including an oxide-resistant sputter layer 165 is disposed on the device side surface of the hermetic seal ferrule over which an ECA stripe is provided. The ECA stripe may comprise one of a thermal-setting electrically conductive adhesive, an electrically conductive polymer, an electrically conductive epoxy, an electrically conductive silicone, an electrically conductive polyimides, or an electrically conductive polyimide, such as those manufactured by Ablestick Corporation. The oxide-free electrical attachment between the ECA stripe and the filter or AIMD circuits may comprise one of gold, platinum, palladium, silver, iridium, rhenium, rhodium, tantalum, tungsten, niobium, zirconium, vanadium, and combinations or alloys thereof.

Abstract: A ceramic reinforced metal composite (CRMC) comprising a composition composite as an interpenetrating network of at least two interconnected composites is described. The interpenetrating networks comprise a ceramic matrix composite (CMC) and a metal matrix composite (MMC). The composition composite is particularly useful as an electrically conductive pathway extending through the ceramic body of a hermetically sealed component, for example, a feedthrough in an active implantable medical device (AIMD).

Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing comprises an open-ended ceramic container having a via hole providing an electrically conductive pathway extending through the container. A metal lid closes the open-end of the container. An electrode assembly housed inside the casing comprises an anode current collector deposited on an inner surface of the ceramic container in contact with the electrically conductive pathway in the via hole. An anode active material contacts the current collector and a cathode active material contacts the metal lid. A separator is disposed between the anode and cathode active materials. That way, the electrically conductive pathway serves as a negative terminal, and the lid, electrically isolated from the conductive pathway by the ceramic container, serves as a positive terminal. The negative and positive terminals are configured for electrical connection to a load.

Abstract: The present invention changes the magnet-mode of an active implantable medical device (AIMD) such that repeated application of a clinical magnet in a predetermined and deliberate time sequence will induce the AIMD to enter into its designed magnet-mode. In one embodiment, a clinical magnet is applied close to and over the AIMD and removed a specified number of times within a specified timing sequence. In another embodiment, the clinical magnet is applied close to and over the AIMD and flipped a specified number of times within a specified timing sequence. This makes it highly unlikely that the magnet in a portable electronic device, children's toy, and the like can inadvertently and dangerously induce AIMD magnet-mode.

Abstract: A feedthrough terminal assembly for active implantable medical devices includes an electrically conductive pad for a convenient attachment of wires from either the circuitry inside the implantable medical device or wires external to the device. The electrically conductive pad enables direct thermal or ultrasonic bonding of a circuit board or lead wire to the terminal pin.

Abstract: The present invention is directed to an electrolyte for an electrolytic capacitor. The capacitor has an electrolytic anode and an electrochemical cathode. The electrolyte has water, a water soluble organic salt, and a relatively weak organic acid. This electrolyte is chemically compatible to aluminum and tantalum oxide dielectrics and withstands higher voltage while maintaining good conductivity. This makes the electrolyte especially useful for high voltage applications, such as occur in an implantable cardiac defibrillator.

Abstract: A hermetically sealed filtered feedthrough assembly attachable to an AIMD includes an insulator hermetically sealing a ferrule opening of an electrically conductive ferrule with a gold braze. A co-fired and electrically conductive sintered paste is disposed within and hermetically seals at least one via hole extending in the insulator. At least one capacitor is disposed on the device side. An active electrical connection electrically connects a capacitor active metallization and the sintered paste. A ground electrical connection electrically connects the gold braze to a capacitor ground metallization, wherein at least a portion of the ground electrical connection physically contacts the gold braze. The dielectric of the capacitor may be less than 1000 k. The ferrule may include an integrally formed peninsula portion extending into the ferrule opening spatially aligned with a ground passageway and metallization of an internally grounded feedthrough capacitor. The sintered paste may be of substantially pure platinum.
