Abstract

The present invention relates to a sensor guide wire (17) for intravascular measurements of physiological variables in a living body, having a proximal region (8), a distal sensor region (9) and a tip region (10). The sensor guide wire (17) further comprises a core wire member (11), a sensor element (14), which has a sensor portion (15), for measuring the physiological variable and to generate a sensor signal in response to said variable and a jacket (13), accommodating at least a part of said sensor element (14). The sensor portion (15), is sensitive to one or many of the physiological variables, pressure, temperature, and flow The core wire member (11) comprises two separate parts, a first core wire part (19) and a second core wire part (20), wherein a distal end (21) of said first core wire part (19) is attached to said jacket (13) proximally said sensor portion (15) and a proximal end (22) of said second core wire part (20) is attached to said jacket (13) distally to said sensor portion (15).
