Abstract: A capacitor having at least two side-by-side anodes with a cathode current collector disposed between the anodes and housed inside a casing is described. Cathode active material is supported on the opposed major faces of the current collector and the current collector/cathode active material subassembly is housed in a first separator envelope. The first separator envelope is positioned between the side-by-side anodes and this electrode assembly is then contained in a second separator envelope. The two anodes can be connected in parallel inside or outside casing, or they can be unconnected to each other. There is also cathode active material supported on inner surfaces of the casing in a face-to-face alignment with an adjacent one of the anodes. That way, the second separator envelope also prevents direct physical contact between the anode pellets and the cathode active material supported on the casing sidewalls.

Abstract: A medical device includes a housing configured for implantation within a body of a patient. Detection circuitry is disposed in the housing and coupled to an electrode arrangement. The detection circuitry is configured to sense a cardiac electrical signal from the patient. A processor is coupled to the detection circuitry and configured to compute a first measure of heart rate variability (HRV) using the cardiac electrical signal, and compute a second measure of HRV using the cardiac electrical signal, the second measure of HRV differing from the first measure of HRV. The processor is also configured to produce an index of patient status derived from a ratio of the first and second measures of HRV, such that the index is a normalized HRV metric personalized to the patient. The processor or a remote system can use the index to assess acute and chronic changes in patient status.

Abstract: An electrochemical cell comprising an electrode assembly having a plurality of cathodes in which the plurality of cathodes is electrically connected together at a connection tab junction is disclosed. The junction preferably comprises a plurality of cathode connection tabs that are folded over each other to construct a junction that is mechanically and electrically robust. The junction is comprised of a plurality of connection tabs that each extend from a cathode. Each of the respective tabs is folded over each other to form a compact electrode junction having redundant connections. An elongated lead extends from the junction to provide an electrical connection to the plurality of cathodes. The junction is welded together such as by a laser, resistance or ultrasonic weld joint. The cathode junction is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

Abstract: A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.

Abstract: A capacitor is described. A casing for the capacitor comprises a container having a face wall joined to a surrounding sidewall extending to a annular edge defining an open end of the container. An inwardly extending protrusion is located intermediate the face wall and the annular edge at the container open end. A partition plate is supported on the protrusion to thereby provide a first capacitor enclosure bounded by the face wall, the surrounding sidewall and the partition plate. A cover plate is secured to the annular edge to close the open end of the container and provide a second capacitor enclosure bounded by the partition plate, the surrounding sidewall and the cover plate. An anode, for example of tantalum, and a cathode active material, for example of ruthenium oxide, reside in capacitive association with each other inside each of the first and second capacitor enclosures. A working electrolyte is also contained in the capacitor enclosures. Finally, leads extend from each anode through insulative seals structures supported by the casing for making electrical connection to the capacitor.

Abstract: The present invention related to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from a combination of vanadium oxide and either a copper or a silver oxide and the other of a copper or a silver nitrate. The cathode material of the present invention provides an increased gravimetric energy density over the cathode active materials of the prior art along with an increased pulse voltage delivery capacity. This makes the cathode material of the present invention particularly useful for implantable medical applications.

Abstract: A capacitor is described. The capacitor comprises a first casing member having a first face wall extending to a first surrounding sidewall in turn extending to a first annular edge defining a first open end. A second casing member has a second face wall extending to a second surrounding sidewall in turn extending to a second annular edge defining a second open end. The second casing member is supported on the first annular edge to thereby close the first open end of the first casing member and provide a first capacitor enclosure comprising the first and second casing members in a stacked relationship. A cover is secured to the second annular edge to close the second casing member and provide a second capacitor enclosure. An anode, for example of tantalum, and a cathode active material, for example of ruthenium oxide, reside in capacitive association with each other inside each of the first and second capacitor enclosures. A working electrolyte is also contained in the capacitor enclosures. Finally, leads extend from each anode through insulative seals structures supported by the casing members for making electrical connection to the capacitor.

Abstract: A magnetic pulse welding process for joining a current collector to a terminal pin in the construction of electrochemical cells is described. The magnetic pulse welding process utilizes a pulsed direct current and an electrically conductive coil to generate an electro-magnetic force that causes two work pieces to collide with each other and form a bond therebetween. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

The flat-through filter includes a first shield plate, an active electrode plate, and a second shield plate where the shield plates are electrically coupled to a metallization which in turn is coupled either to the ferrule or AIMD housing. The feedthrough includes an alumina substrate comprised of at least 96% alumina and a via hole with a substantially closed pore and substantially pure platinum fill. The platinum fill forms a tortuous and mutually conformal knitline or interface between the alumina substrate and the platinum fill, wherein the platinum fill is electrically coupled to at least one active electrode plate in non-conductive relationship to the at least one first and second shield plates.
