Abstract: A method for manufacturing a ceramic substrate by a 3D-printing process is described. The method comprises operating a 3D-printer to print a green-state ceramic body having a height extending to spaced apart first and second end surfaces and at least one via extending at least part-way along the height of the green-state ceramic body from the first end surface toward the second end surface. Then, the green-state ceramic body is sintered to provide the ceramic substrate with the at least one via. In cross-section, the at least one via has a square-shaped via with rounded corners.

Abstract: In various examples, a method of making a guidewire is described. The method includes placing a polymer jacket over a core wire. The core wire includes a first portion having a first profile and a second portion having a second profile. The first profile is smaller than the second profile. Heat is applied to the polymer jacket and the core wire to reflow the polymer jacket and fuse the polymer jacket to the core wire, wherein the polymer jacket forms a layer of substantially uniform thickness along a length of the core wire. In some examples, a guidewire made using the method is also described.

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: 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.
