Abstract: An electrochemical cell having a casing housing an electrode assembly of a separator residing between a lithium anode and a cathode comprising silver vanadium oxide and fluorinated carbon is described. The electrode assembly is activated with a nonaqueous electrolyte comprising a lithium salt dissolved in a solvent system of propylene carbonate mixed with 1,2-dimethoxyethane, lithium bis(oxalato)borate (LiBOB), and fluoroethylene carbonate (FEC). Preferably LiBOB is present in an amount ranging from about 0.005 wt. 5 to about 5 wt. %, and FEC is present in an amount ranging from about 0.01 wt. % to about 10 wt. %. This electrolyte formulation is more conductive than the conventional or prior art binary and ternary solvent system electrolytes while being chemically and electrochemically stable toward Li/SVO cells, Li-SVO/CFx mixture cells, and Li-SVO/CFx sandwich cathode primary electrochemical cells.

Abstract: In various examples, a method of establishing a communication session between an external device and an implantable medical device is described. The method includes generating at the external device a first private key and a first public key. A start session order is sent over a long-range communication channel. Evidence of physical proximity is sent from the external device to the implantable medical device over a short-range communication channel. A second private key and a second public key are generated at the implantable medical device. A first shared key is generated by the implantable medical device using the first public key and the second private key. A second shared key is generated by the external device using the second public key and the first private key. The first and second shared keys are used to encrypt and decrypt one or more messages between the external device and the implantable medical device.

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.
