The Food & Drug Administration cleared the Tensys T-Line, Tensys Medical s lead product, in 2002 for noninvasive, continuous real-time blood pressure monitoring. Tensys T-Line measures a patient's blood pressure at the radial artery. It offers anesthesiologists more control in regards to patient safety during surgery by allowing them to quickly monitor and manage blood pressure variations. The T-Line provides continuous, real-time data and has clinically equivalent accuracy to that of the arterial line. The device is based on Tensymetry, the company's proprietary and patented technology for noninvasively extracting the continuous, beat-to-beat pressure waveform from the radial artery without the use of any external calibration device. Founded in 1995, Tensys Medical is located in San Diego.
