A sterile, noninvasive, non-luminal, electronic device designed to be connected to an appropriate invasive luminal device (e.g., catheter, cannula, tube, needle), to detect pressures (e.g., blood, gastrointestinal, urinary pressures) within the lumen and transmit them as electrical signals to an appropriate monitoring device. It consists of a pressure transducer and a connection cable and may be designed to be used with a pressure transducer dome. This is a single-use device.
