Abstract: An electrode arrangement for low artifact electrocardiogram (ECG) monitoring and defibrillation, comprises at least one conductor print line body having a large silver conductor print line area functioning as a defibrillation area and a small silver-silver chloride (Ag/AgCl) conductor print line area functioning as a sensing area, at least one non halide defibrillation gel layer and halide containing sensing gel layer configured to attach with the defibrillation area and sensing area respectively, and at least one insulated conductive ink line for connecting the conductor print line body to a cable that provides an electrical communication between the conductor print line body and an external equipment. When direct current runs through the conductor print line body, the large silver conductor print line area polarizes and the small Ag/AgCl conductor print line area does not polarize so that small Ag/AgCl conductor print line area senses ECG signal leading to low motion artifact.

Abstract: An electrode providing electrical contact with a patient's skin includes a conductive member adapted for connection to an external electrical apparatus and a non-liquid water containing film for electrically interfacing to said patient's skin, the non-liquid film being electrically and mechanically connected to said conductive member. The non-liquid water containing film includes an electrically conductive organic polymer plasticized with a polyhydric alcohol with said organic polymer being derived from a monomeric mixture comprising from about 2 to 30 pph acrylic acid, 2 to 30 pph of a glycolvinylether and 0.01 to 1.5 pph of a crosslinking agent. Preferably the polyhydric alcohol is glycerol.

Abstract: Medical devices having at least a portion thereof coated with a lubricious polymer are disclosed. The lubricious polymer can be, for instance, a hydrogel polymer, such as a quaternary amine acrylate polymer. To bond the lubricious polymer to the surface of the medical device, the medical device is first subjected to a solvent and a multi-functional monomer. The solvent causes the multi-functional monomer to become imbibed into the surface of the medical device. Thereafter, a polymer having lubricious properties is polymerized on the surface of the device. The multi-functional monomer reacts with the polymer coating securely affixing the polymer coating to the device.

Abstract: A heater for burning fuel having a hollow enclosure with an air inlet, and a combustion gas outlet. The enclosure has an exterior heat exchange wall preferably directly exposed to ambient air and an interior surface defining a combustion chamber. The enclosure has a body with front and rear openings into which are fitted a front panel and a rear panel defining joints therebetween. The interior surface of the enclosure is coated and joints are sealed with heat resistant anti-oxidant material, for example: porcelain enamel, having a co-efficient of thermal expansion not substantially greater than the co-efficient of thermal expansion of the enclosure.
