Tube and sensor guide wire comprising tube

A sensor guide wire for an intravascular measurement of at least one variable in a living body, the sensor guide wire having a proximal region, a distal sensor region and a tip region, the sensor guide wire comprising:

• a sensor element arranged in the sensor region, the sensor element comprising a sensor portion configured to measure the variable and to generate a sensor signal in response to the variable;
• and
• a tube that extends at least partly along the proximal region of the sensor guide wire,
• wherein the tube has a longitudinal extension along a longitudinal axis,
• wherein the tube comprises a tube wall having a thickness and a plurality of through-going slots,
• wherein each slot of the plurality of through-going slots has an elongated shape along a main extension extending along a circumference of the tube such that each slot has a width and a length along the main extension,
• wherein the plurality of slots are divided into a plurality of sets of slots,
• wherein each set of slots is assigned to a perpendicular plane that runs perpendicular to the longitudinal axis such that the main extensions of the slots within each set are in their respective plane,
• wherein the planes to which the sets of slots are assigned are provided along the tube,
• wherein the lengths of the slots in a same perpendicular plane are essentially equal, and
• wherein the lengths of the slots in different perpendicular planes vary along the longitudinal extension of the tube according to a predefined pattern in at least one section of the tube.

A tube for an intravascular medical device, the tube having a longitudinal extension along a longitudinal axis, the tube comprising:

• a tube wall having a thickness and a plurality of through-going slots,
• wherein each slot of the plurality of through-going slots has an elongated shape along a main extension extending along a circumference of the tube such that each slot has a width and a length along the main extension,
• wherein the plurality of slots are divided into a plurality of sets of slots,
• wherein each set of slots is assigned to a perpendicular plane that runs perpendicular to the longitudinal axis such that the main extensions of the slots within each set are in their respective plane,
• wherein the planes to which the sets of slots are assigned are provided along the tube,
• wherein adjacent perpendicular planes are separated by a predetermined separation distance, and
• wherein the separation distance between adjacent planes varies along the longitudinal extension of the tube.
