Abstract: The present invention is directed to methods, compositions and devices useful for the detection and/or quantification of a microbial contaminant, including an endotoxin. In embodiments, cartridges are provided that suitably include dried compositions that are useful in absorbance-based assays and in combination with portable readers/devices.

Abstract: Example deflectable catheter systems are described. An example deflectable catheter system includes a housing, an orienting member, an actuator, a first elongate member, a second elongate member, and a wire member. The housing defines a passageway. The orienting member is attached to the housing. The actuator is attached to the orienting member and is moveable between an actuator first position and an actuator second position. The first elongate member is attached to the orienting member and defines a lumen. The first elongate member is moveable between a first, substantially straight configuration when the actuator is in the actuator first position and a second, curved configuration when the actuator is in the actuator second position. The second elongate member is disposed through the passageway of the housing and extends through the lumen defined by the first elongate member. The second elongate member is rotatable relative to the first elongate member.

Abstract: A device for controlling electrical power supply in response to air pressure measurement includes an airflow path, a chamber having an aperture, a liquid flow restrictor configured to inhibit ingress of liquid into the chamber via the aperture, a pressure sensor located in the chamber and operable to detect, in the presence of the liquid flow restrictor, air pressure changes caused by air flow in the airflow path, and a circuit for converting air pressure changes detected by the pressure sensor to control signals for controlling output of power from a battery.
