Abstract: An absorbent quantitative test device in the form of a flat patch. When placed on the skin of a subject; the device collects a fixed volume of sweat. It is particularly intended to be used in screen testing for cystic fibrosis by measuring the chloride level in sweat and providing a visual indication when the level is in excess of a predetermined concentration. A fill tab indicator undergoes a color change when the fixed volume of sweat has been collected signifying completion of the test. The device includes two concentric circular reaction areas of chemically treated absorbent paper or the like. The sweat sample is introduced into the device at the center of the first or inner circular reaction area which contains a chemical composition capable of reacting with all chloride in the sweat sample below a predetermined concentration value to screen out that amount of chloride.

Abstract: Battery cathodes of the iodine-complex type including one or more additives for improved iodine utilization.

Abstract: An improved medical electrode particularly adaptable to tape-like configurations for use in sensing and stimulation applications in which the electrode is applied to the skin. An essential electrode component comprises a mixture of a polymerized form of 2-acrylamido-2-methylpropanesulfonic acid or one of its salts with water and/or an alcohol. The mixture possesses electrically conductive properties, flexible properties and adhesive properties particularly lending itself to skin contact and adhesion.

Abstract: Novel cathode materials for use in electrochemical cells are disclosed. The cathode materials consist essentially of a conductive solution comprised of iodine dissolved in a mixture of two organic pyridine-based constituents, both of which function as donors to form complexes with iodine. Preferably, the cathode materials further include, in addition to the dissolved iodine, an iodine solid phase suspended therein. Large amounts of the iodine solid phase, relative to the dissolved iodine, may be used.

Abstract: A preformed electrical connector for use with body implantable stimulators, such as heart pacemakers, having a signal generator and at least one electrical lead electrically and mechanically connected to each other through the preformed electrical connector. The connector carries at least one terminal to establish electrical contact between the signal generator and electric lead, passageways being provided in the connector body to accept and guide the signal generator feedthrough pin and electrical lead into contact with the terminal. In a preferred embodiment, the terminal is provided with intersecting bores such that the feedthrough pin and electrical lead form electrical contact within or by means of the terminal. The pin may be welded or press fit to the terminal and the lead may be attached to the terminal by means of a setscrew. The preformed connector may be mechanically fastened or fastened with an adhesive to the implantable stimulator.
