Abstract: An active implantable medical device (AIMD) is described. The AIMD has a rechargeable electrical energy power source connected to a PCB assembly for powering the medical device. The AIMD can sense biological signals from a patient, or it can have at least two electrodes that provide stimulation therapy to the patient. An inductive charging coil housed inside an elongate device enclosure is connected to the power source. The inductive charging coil has winds of an electrically conductive wire or tape that wrap around the PCB. The winds of the inductive charging coil have an upper wind portion residing above the PCB and a lower wind portion below the PCB. Opposed curved ends of the inductive charging coil winds are continuous with the upper and lower wind portions. This structure provides the inductive charging coil with a length aligned along a longitudinal axis of the PCB. In that manner, the inductive charging coil occupies a space otherwise not used in an elongate cylindrical enclosure for an 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: A wet tantalum electrolytic capacitor containing a cathode, fluidic working electrolyte, and anode formed from an anodically oxidized sintered porous tantalum pellet is provided. The pellet is formed from a pressed tantalum powder. The tantalum powder is formed by reacting a tantalum oxide compound, for example, tantalum pentoxide, with a reducing agent that contains a metal having an oxidation state of 2 or more, for example, magnesium. The resulting tantalum powder is nodular or angular and has a specific charge that ranges from about 11,000 μF*V/g to about 14,000 μF*V/g. Using this powder, wet tantalum electrolytic capacitors have breakdown voltages that ranges from about 250 volts to about 400 volts. This makes the electrolytic capacitors ideal for use in an implantable medical device.

Abstract: A lead adapter for a patient treatment system comprises a housing having a plurality of inlets, each inlet being segregated from an immediately adjacent inlet by a housing intermediate wall. A plurality of electrical contact assemblies residing in the housing are electrically connected to a respective one of a plurality of electrical contact posts. Each contact post has an exposed terminal portion residing in one of the plurality of inlets. A header is movably secured to the housing to selectively open and close the housing. With the header in an open position, an implantable lead is movable into a longitudinally extending opening in the header. The header is then manipulatable into a closed position to move an electrical contact of the lead into contact with a respective one of the electrical contact assemblies electrically connected to a respective one of the electrical contact posts. That way, the electrical contacts of the implantable lead are in electrical continuity with an exposed terminal portion of a respective one of the electrical contact posts.

Abstract: A filtered feedthrough assembly includes a ferrule configured to be installed in an AIMD housing. An insulator is disposed within a ferrule opening. A conductive pathway is disposed within a passageway through the insulator. A filter capacitor is disposed on a device side having active and ground electrode plates disposed within a capacitor dielectric k greater than 0 and less than 1,000. A capacitor active metallization is electrically connected to the active electrode plates. A ground capacitor metallization is electrically connected to the ground electrode plates. The filter capacitor is the first filter capacitor electrically connected to the conductive pathway coming from a body fluid side into the device side. An active electrical connection electrically connects the conductive pathway to the capacitor active metallization. A ground electrical connection electrically connects the ground capacitor metallization to the ferrule. The filter capacitor is a flat-through or an X2Y attenuator filter capacitor.

Abstract: A lid assembly for an electrochemical cell comprises a plate-shaped lid having an opening and a glass-to-metal seal (GTMS) residing in the lid opening. The GTMS does not have a ferrule. Instead, the GTMS has a sealing glass that seals directly to a terminal pin and to the lid. The terminal pin has an enlarged diameter pin section contacted by the sealing glass and a first reduced diameter pin section extending axially outwardly from the enlarged diameter pin section. An electrochemical cell provided with the lid assembly is also described.
