Endotracheal Tubes requiring sensors (e.g. for measurement of patient vital signs, temperature, chemical, or for nerve monitoring and/or stimulation). Micropen Medical has core competencies for the printing of biocompatible materials onto flexible, inflatable, three-dimensional balloons and tubes. Our features are integrated into the tube creating a very low profile device that enables nerve monitoring or stimulation, measurement of patient vital signs, temperature, and pH. Our approach increases flexibility, eases insertion and placement, is ready to use and results in better patient comfort. Cuff and non-cuff printed tubes are available now. Multi-lumen tubes and pediatric tubes are under development and will available 1st qtr. 2013.
