摘要： The invention is a method of removing a miniature implantable electronic device (22) by means of an integral eyelet (30) or circumferential ring to facilitate removal of the implanted device without surgery. The string (32), if to radio-opaque, provides a method of locating the miniature implantable device without surgery and attachment of one end of the string to a radio-opaque marker provides a method of locating the end of the string to facilitate non-surgical removal of the miniature implantable device from living tissue. Alternatively, the miniature implantable device may be placed in a silk tube prior to being implanted in the living tissue, to facilitate removal from the tissue. Additionally, the eyelet increases the life of the miniature implantable device, if it is made of a metal, such as platinum or iridium, which has a low metal-to-electrolyte voltage drop by virtue of improved electrical coupling to a saline solution.

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.
