Abstract: A sensor and guide wire assembly (21; 41) for intravascular measurements of a physiological variable in a living body, comprises a sensor element (22; 42) and a sensor guide wire (23; 43) comprising a core wire (28; 48) and at least one signal transmitting cable (31; 51) connected to the sensor element, wherein a polymer layer (27; 47) is provided which encloses a portion of the core wire and the at least one signal transmitting cable.

Abstract: Sensor and guide wire assembly (1; 21) for intravascular measurement of physical variables inside a living body and comprises a proximal end portion (2; 22) and a sensor element (9; 29), which is located in a distal portion of the sensor and guide wire assembly (1; 21), and is characterized in that a proximal tube (3; 23) is provided, which extends from said proximal portion (2; 22) to a proximal end of a hollow stranded wire (4; 24), which extends to the distal end portion wherein the sensor element (9; 29) is located.
