Abstract: A lubricant coating vehicle for medical devices used to reduce the coefficient of friction of such devices upon exposure thereof to moisture. The lubricant coating vehicle allows the introduction of a pharmacological additive having a release rate that is within acceptable pharmacokinetic criteria. The release rate is adjusted by utilizing different salt forms of the additive and adjusting the concentration of a urethane pre-polymer.
Abstract: A valve position monitor that provides simultaneous visual and electrical signals of valve position is disclosed. A method of monitoring the position of a valve by utilizing the valve position monitor described herein is also disclosed.

Abstract: A cable suitable for detecting the presence of corrosive liquids is disclosed. In an embodiment the cable includes two sensing wires wrapped around a core member, at least one of the sensing wires being surrounded by a non-conductive surface layer. In an alternate embodiment the cable includes two sensing wires wrapped around a core member, the sensing wires and core member being encapsulated by a non-conductive surface layer. Preferably, the cable includes insulating wires for detecting the location of a leak. When a corrosive liquid contacts the sensing wires of the cable an electrical connection is created between them.
