    Abstract: An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active end metallization that is electrically connected to the active electrode plates and a ground end metallization that is electrically connected to the at least one ground electrode plates of the chip capacitor. There is a ground path electrically extending between the ground end metallization of the chip capacitor and the ferrule. The ground path comprises at least a first electrical connection material connected directly to the first gold braze, and at least an internal ground plate disposed within the circuit board substrate with the internal ground plate being electrically connected to both the first electrical connection material and the ground end metallization of the chip capacitor. An active path electrically extends between the active end metallization of the chip capacitor and the lead wire.

    Abstract: An electrochemical cell comprising a cathode and an anode residing within a casing, the anode being positioned distal of the cathode. The cathode having a cathode current collector having an angled configuration that encourages the cathode active material to move in an axial distal direction during cell discharge. The cathode current collector may be configured having at least one fold thereby dividing the current collector into at least two portions having an angle therebetween. The cathode current collector may comprise a wire having a helical configuration or the cathode current collector may comprise a post with a thread having a helical orientation about the post exterior. A preferred chemistry is a lithium/CFx activated with a nonaqueous electrolyte.

    Abstract: A medical device includes a housing and an electrode arrangement coupled to the housing and configured to sense an electrical physiologic signal from a patient. The device also includes detection circuitry coupled to the electrode arrangement and configured to obtain a cardiac signal component and a non-cardiac signal component from the physiological signal. A processor is coupled to the detection circuitry. The processor is configured to detect patient activity using at least the non-cardiac signal component and discriminate between voluntary and involuntary activity of the patient based on a comparison of temporally aligned cardiac and non-cardiac signal components.

    Abstract: In various examples, an apparatus is configured for subcutaneously inserting an implantable device within a patient. The apparatus includes a dilator portion including a dilator including a dilator length. The dilator portion is configured to separate tissue to create a subcutaneous pocket within the patient sized and shaped to accommodate an implantable device within the subcutaneous pocket. A sheath portion includes a sheath sized and shaped to accommodate the dilator within a sheath lumen. The sheath is configured to accommodate an antenna of the implantable device with the dilator removed from within the sheath. The sheath includes a sheath length that is at least substantially as long as an antenna length. The sheath is configured to separate to allow removal of the sheath around the implantable device to remove the sheath from and leave the implantable device within the subcutaneous pocket within the patient.
