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.

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: 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.

Abstract: A lithium electrochemical cell with increased energy density is described. The electrochemical cell comprises an improved sandwich cathode design with a second cathode active material of a relatively high energy density but of a relatively low rate capability sandwiched between two current collectors and with a first cathode active material having a relatively low energy density but of a relatively high rate capability in contact with the opposite sides of the two current collectors. In addition, a cathode fabrication process is described that increases manufacturing efficiency. The cathode fabrication process comprises a process in which first and second cathode active materials are directly applied to opposite surfaces of a perforated current collector and laminated together. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.

Abstract: A miniature electrochemical cell having a total volume that is less than 0.5 cc is described. The cell casing is formed by joining two ceramic casing halves together. One or both casing halves are machined from ceramic to provide a recess that is sized and shaped to contain the electrode assembly. The opposite polarity terminals are metal feedthroughs, such as of gold, and are formed by brazing gold into openings machined into one or both ceramic casing halves. The two ceramic casing halves are separated from each other by a metal interlayer, such as of gold, bonded to a thin film metallization adhesion layer, such as of titanium, that contacts an edge periphery of each ceramic casing half. A solid electrolyte (LixPOyNz) is used to activate the electrode assembly.

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 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).
