Abstract: An active medical device has a feedthrough with at least two terminal pins that are connected to electronic components in the device housing. A lead connector is connected to a strain-relief device for a lead. The lead connector supports at least two proximally-facing C-shaped inserts with an annular spring nested therein that are detachably connected to the device terminal pins to thereby connect the device electronic components to the lead electrodes. The device housing has a length extending along a longitudinal axis, and secondary axes of the terminal pins connected to the C-shaped inserts/annular springs are aligned parallel to the axis with imaginary extensions of the connector axes extending into the device housing.

Abstract: An electrical energy power source comprises a casing made by micro-bonding an upper ceramic wafer and a lower ceramic wafer to the opposed surfaces of a ceramic ring. The upper and lower ceramic wafers have respective first and second conductive pathways extends therethrough. A first current collector supporting a first active material layer contacts the upper ceramic wafer and the first conductive pathway, and a second current collector supporting a second, opposite polarity active material layer contacts the lower ceramic wafer and the second conductive pathway. A separator resides between the first and second active materials, and an electrolyte filled into the casing through a fill port activates the active materials. The first and second conductive pathways serve as opposite polarity terminals for the power source.

Abstract: In various examples, a system includes a steerable medical device including a handle including a longitudinal axis. An elongate shaft extends distally from the handle. The elongate shaft includes a distal tip and a lumen through the elongate shaft. At least four pullwires are disposed within the handle and extending to and anchored proximate the distal tip of the elongate shaft. At least two actuators are associated with the handle. The at least two actuators are operably coupled to the at least four pullwires with actuation of the first actuator causing tension in the first or second pullwire to deflect the distal tip in a first or second tip direction, respectively, and actuation of the second actuator causing tension in the third or fourth pullwire to deflect the distal tip in a third or fourth tip direction, respectively.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper lid. The lid has a sealed electrolyte fill port that is axially aligned with an annulus residing between the inner surface of the annular sidewall and the electrode assembly. The fill port axially aligned with the annulus between the electrode assembly and the casing sidewall allows the casing to be filled with electrolyte using a vacuum filling process so that activating electrolyte readily wets the anode and cathode active materials and the intermediate separator.

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 active implantable medical device (AIMD) has an alumina housing supporting at least two electrodes. A printed circuit board (PCB) assembly resides inside the housing. Two sintered platinum-containing pathways extend through the housing thickness from the electrodes supported on the housing body fluid side surface to a housing device side surface. A device side end of each of the two platinum-containing pathways is in electrical continuity with an electrical contact supported on the PCB to energize the electrodes for providing stimulation therapy to a patient or for sensing biological signals from the patient.

Abstract: A wet tantalum electrolytic capacitor containing a cathode, fluidic working electrolyte, and anode formed from an anodically oxidized sintered porous tantalum pellet is described. 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 9,000 μF*V/g to about 11,000 μF*V/g. Using this powder, wet tantalum electrolytic capacitors have breakdown voltages that ranges from about 340 volts to about 450 volts. This makes the electrolytic capacitors ideal for use in an implantable medical device.

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 electrically conductive feedthroughs or pathways, such as of gold, and are formed by brazing gold into tapered via holes 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 layer, such as of titanium, that contacts an edge periphery of each ceramic casing half. A solid electrolyte of LiPON (LixPOyNz) is used to activate the electrode assembly.
