Abstract: An implantable transvenous defibrillation/cardioversion lead. The lead extends from a proximal end carrying electrical connectors to a bifurcated distal end. Distal to the bifurcation are a first, generally straight leg and a second, curved leg. In use, the distal end of the first, generally straight leg is located in the apex of the right ventricle and the distal end of the second, generally curved leg is located in the outflow tract from the right ventricle, with the point of bifurcation located approximately adjacent the tricuspid valve. Elongated coil electrodes are provided extending along the straight and curved legs, distal to the point of bifurcation of lead. The lead may be used in conjunction with a subcutaneous or othe additional defibrillation/cardioversion electrode.

Abstract: Preparation of 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.
