Abstract:
1. A sensor guide wire for intravascular measurement of a physiological variable in a living body, comprising: at least two elongate sections, a first tubular elongate section being tubular in a longitudinal direction of the sensor guide wire, and a second elongate section that is adapted to be inserted a first predetermined distance into said first tubular elongate section, a sensor element provided in a distal part of said sensor guide wire, for measuring the physiological variable and to generate a sensor signal in response to said variable, and at least one signal transmitting signal line connected to the sensor element to transmit the sensor signal to a connector provided in a proximal part of said sensor guide wire, wherein the first tubular elongate section is provided with at least one through-going opening in a direction perpendicular to the longitudinal direction of the guide wire and positioned a second predetermined distance from one end of the first tubular elongate section, and wherein the guide wire comprises a locking member that is configured to be inserted into the through-going opening from outside the first tubular elongate section and attached to an outer surface of the second elongate section.
