Abstract
A sensor guide has a sensor element, an electronic unit, a signal transmitting cable connecting the sensor element to the electronic unit, a flexible tube having the cable and the sensor element disposed therein, a solid metal wire having a plurality of sections with differing thicknesses such that each of the sections has a different flexibility, and a coil which is attached to a distal end of the wire. An inside portion of the flexible tube acts as an air channel to establish communication between the sensor element and atmospheric pressure. In addition, the wire is rigidly disposed in the sensor guide and extends along the entire sensor guide inside of the tube. Moreover, one of the plurality of sections is an enlarged portion having a slot therein and the sensor element is disclosed in the slot between the coil and the proximal end of the wire.
