摘要： A capacitive filter feedthrough assembly and method of making the same are disclosed for shielding an implantable medical device such as pacemaker or defibrillator from electromagnetic interference or noise. A ferrule is adapted for mounting onto a conductive device housing by welding, soldering, brazing or gluing, and supports a terminal pin for feedthrough passage to a housing interior. A capacitive filter is mounted at the inboard side of a device housing, with capacitive filter electrode plate sets coupled respectively to the housing and the terminal pin by an electrically conductive combination of solder and brazing. In one embodiment of the invention, multiple capacitive filters are provided in an array within a common base structure, where each capacitive filter is associated with a respective terminal pin.

摘要： Structures and methods relating to electrodes for incorporation into a feedthrough with a profile adapted for subcutaneous sensing of physiologic and cardiac signals. Electrode assemblies are adapted for integration with feedthrough to enable maximal electrode spacing, minimal myopotential electrical noise and provide reliable insulation from the IMD housing. Various structures and manufacturing processes are implemented to provide a large sensing surface with a low profile. The subcutaneous sensing electrode assembly provides a leadless sensing system and further enhances installation and follow-up procedures.

摘要： An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.

摘要： A centerless grinding method of finishing feedthrough pins and corresponding devices for use in implantable medical devices and for components such as batteries in implantable medical devices is disclosed. The method provides certain advantages, including the elimination of longitudinal anomalies in drawn wire to thereby improve the hermeticity of implantable medical devices. In one of the preferred methods, the surface of an over-size medical grade wire having a known anomaly depth is centerless ground using an abrasive wheel and suitable coolant to a layer past which those anomalies disappear.
