Abstract: A needle or catheter is received within a region of the body at which fluid pressure is to be measured. At its external end, the needle/catheter is connected to a chamber which also includes a strain-gage sensor. A saline solution is supplied to the chamber and internal parts of the needle/catheter during pressure measurement via a conduit passing through parts of the straingage sensor assembly. The conduit terminates at a special orifice and channel on the surface wall of the sensor assembly to provide a perfusing of the chamber and inner parts of the needle/catheter at a very slow rate and with negligible back pressure.
