A tube for an intravascular medical device has a longitudinal extension along a longitudinal axis. The tube comprises a tube wall having a specified thickness and a plurality of through-going slots, wherein each slot has an essentially elongated shape along a main extension extending along the circumference of the tube. At least two slots are provided in a plane perpendicular to the longitudinal axis such that the main extension of the at least two slots are in the perpendicular plane. The lengths of the slots in the same perpendicular plane P are essentially the same, and the lengths L of the slots in different planes vary along the longitudinal extension of the tube according to a predefined pattern. A sensor guide wire for an intravascular measurement of at least one variable in a living body may comprise such a tube.
