    摘要： Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitors, which stores and delivers one or more life-saving bursts of electric charge to a fibrillating heart. These capacitors make up about one third the total size of the defibrillators. Unfortunately, conventional manufacturers of these capacitors have paid little or no attention to reducing the size of these capacitors through improved capacitor packaging. Accordingly, the inventors contravened several conventional manufacturing principles and practices to devise unique space-saving packaging that allows dramatic size reduction. One embodiment of the invention uses thinner and narrower separators and top and bottom insulative inserts to achieve a 330-volt operating, 390-volt surge, 190-microfarad, 30-Joule aluminum electrolytic capacitor which is 33 percent smaller than conventional capacitors having similar electrical traits.

    摘要： An exemplary capacitor has a capacitor stack positioned in a case with a conductor positioned between the case and a lid. In one embodiment the conductor is positioned between the lid and an upper rim of the case and is welded to the lid and case. In one aspect, a capacitor constructed with round wire connectors for interconnecting anode and cathode layers. In one aspect, a configuration for electrically connecting a terminal wire to a capacitor case in which an end of the wire is attached to the case in end-on fashion. The terminal wire may have an expanded end for attaching to the capacitor case in a manner that minimizes the effect on the height profile of the case.

    摘要： Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitor, which stores and delivers life-saving bursts of electric charge to a fibrillating heart. To reduce capacitor size, manufacturers have developed special aluminum foils, such as core-etched and tunnel-etched aluminum foils. Unfortunately, core-etched foils don't work well in multiple-anode capacitors, and tunnel-etched foils are brittle and tend to break when making some common types of capacitors. Accordingly, the inventors devised a new foil structure having perforations and cavities. In an exemplary embodiment, each perforation and cavity has a cross-sectional area, with the perforations having a larger, for example, 2 to 100 times larger, average cross-sectional area than the cavities. Other embodiments of the invention include foil assemblies, capacitors, and implantable defibrillators that benefit from properties of the new foil structure.

    摘要： In one aspect, a method of manufacturing a capacitor includes disposing one or more conductive layers of a first electrode stack in a recess of an alignment mechanism, where the recess is positioned relative to two or more alignment elements. The method further includes placing a separator over the one or more conductive layers where an outer edge of the separator contacts the two or more alignment elements. In one embodiment, a capacitor includes anode and cathode foils having offsetting edge portions. In one embodiment, a multiple tab cathode for a flat capacitor. A plurality of cathode tabs are portioned into a plurality of cathode tab groups positioned in different locations along the edge of the capacitor stack to reduce the amount of space required for connecting and routing the cathode tabs.

    摘要： An implantable connector, implantable lead assemblies, and implantable lead assembly kits are provided. The connector comprises an electrically insulative receptacle having a port configured for receiving an electrical lead body portion that carries an electrical terminal, and an electrical spring clip contact mounted within the receptacle. The electrical contact includes a collar and opposing lever arms. The collar is configured for being placed between an expanded state for receiving the terminal therein when the lead body portion is received within the port, and a collapsed state to firmly engage the terminal. The opposing lever arms are configured for being displaced using a tool to correspondingly place the collar between the expanded state and the collapsed state. The implantable connector can be incorporated into a lead and used to receive another lead to form the lead assembly. A tool can be provided with the connector to provide the lead assembly kit.
