Abstract: A vascular occlusion catheter includes a proximal outer shaft, a distal outer shaft distally terminating with an atraumatic tip, and an occlusion balloon therebetween. The proximal shaft has first and second internal lumens, the first internal lumen being in fluid communication with the balloon. The distal shaft has a distal internal lumen. A hypotube extends through the first internal lumen, through the balloon and into communication with the distal internal lumen. A first window is formed in the proximal shaft and a proximal sensor is positioned within the second internal lumen at the window. A second window is formed in the distal shaft and a distal sensor is positioned within the distal internal lumen at the window. A display hub is positioned along the proximal shaft and electrically connected with the sensors The uninflated vascular occlusion catheter has a greatest outer diameter of seven French or less.

Abstract: A self-correcting autocalibrating analyzer for the direct determination of liquid vapor pressure and determination of the temperature at which a given ratio of vapor to liquid will exert a predetermined pressure in a container of predetermined volume. Test volumes within the analyzer can be automatically calibrated, and corrections for dissolved air in the liquid sample and/or for temperature-related changes in the liquid sample size can be made. The analyzer can set an alarm when unprogrammed variation is detected in preset volumes or when successive vapor pressure determinations of standard liquids vary by more than a predetermined amount.
