摘要： The invention is a method of qualifying an implantable ceramic component made of high-purity dense yttria tetragonal zirconium oxide polycrystal (Y-TZP) by application of non-destructive tests. Specifically, a qualified Y-TZP ceramic component or witness sample is examined by X-ray diffraction to determine the initial monoclinic phase content. The component or witness sample is exposed to steam at 127°C for a predetermined period of time, preferably six hours. The monoclinic phase content is determined for the post-exposure sample. The absolute difference between the initial monoclinic phase content and the post-exposure monoclinic phase content is calculated by difference. If the difference is less than 2.1% the sample is accepted. In an alternate embodiment, the components that pass the screening test are examined by ultrasonic testing to evaluate soundness of the ceramic component. Any component that presents a flaw of greater than three microns is rejected.

摘要： A housing for an implantable medical device in the shape of a hollow magnetic field concentrating tube about which an electrically conductive wire coil is wound and within which medical device electronics is housed. The tube, preferably made of ferrite, is encased in a protective sleeve formed of a material that is impervious to body fluids. The coil provides an electrical output as a result of being exposed to a varying magnetic field that is concentrated around the coil by virtue of the field concentrating tube. The output of the coil is utilized as part of a power supply for the medical device electronics. The sleeve has a generally cylindrical cross-section having an outside diameter of about 3.175 mm and an axial length in the range of about 3.2 mm to 8 mm.

摘要： An improved electrode assembly (16) for batteries and the like including a central mandrel (20) configured to exert a resilient outward force on a multilayer web (18) wound around the mandrel. The multilayer web includes a positive electrode layer, a negative electrode layer, and a separator layer separating the positive and negative layers. The resilient outward force acts to maintain the tightness of the web roll, thus lowering electrical resistance and enhancing battery cycle life. The mandrel is preferably formed of sheet metal configured to define an S-shape having a central section and first and second resilient leaves (40, 42) extending therefrom. The leaves preferably define substantially planar areas for bearing against an inner turn of the web roll to exert a resilient outward thereagainst.
