Abstract
A device for physiological pressure monitoring comprises a miniaturized pressure sensor element which is located near the tip of a guide, which in turn is inserted into a catheter. The guide and the catheter have sealing surfaces which can be brought into contact with each other by axial or rotary motion of the guide in relation to the catheter, whereby the sensor element becomes available for calibration from a pressure generator connected to the catheter.
