Abstract: A central venous catheter is provided having an outer tubular member and an inner tubular member that are preferably formed as a single integrated tube containing polymer material of different durometer and varying amounts of radiopaque filler material. The polymer durometer of the inner tubular member is higher than the polymer durometer of the outer tubular member. The percentage by weight of the filler material contained in the inner tubular member is higher than that of the outer tubular member. The combination of the higher durometer inner tubular member and the lower durometer outer tubular member along the length of the tube provides the desired tensile strength, hardness, chemical resistance and fatigue resistance and at the same time provides the desired flexibility and radiopacity.

Abstract: A vascular access catheter having a catheter hub assembly and a catheter shaft having a plurality of lumens is disclosed. The hub assembly has a body with an interior cavity and an exterior surface with a plurality of openings that are configured to receive the catheter shaft and a plurality of extension tubes, which are fluidly connected to lumens of the catheter shaft. A vascular access port having a housing, at least one reservoir and a self-sealing septum having an outer surface, is positioned partially therein the interior cavity of the body. A portion of the housing defines a reservoir outlet stem that is in fluid communication with the reservoir. At least a portion of the outer surface of the septum is defined therein a port opening that is defined therein the body and is circumferentially surrounded by portions of the exterior surface of the hub body.

Abstract: A fuel cell system includes a fuel cell stack and a thermostat. The thermostat is mounted to the fuel cell stack to regulate a flow of coolant.

Abstract: The invention generally relates to a method and apparatus for collecting condensate from process streams in an integrated fuel cell system. In one aspect, the invention provides a water management subsystem for a fuel cell system. A gas conduit contains a gas at a first pressure. A water tank in the system contains water at a certain level. The water tank has an inlet orifice below the water level. A drain conduit has a first end and a second end. The drain conduit is connected at the first end to the gas conduit, and the drain conduit is connected at the second end to the inlet orifice of the water tank. The water level and the inlet orifice have a vertical height of water between them corresponding to a head pressure greater than the first pressure.
