Intravascular medical devices including laser cut tube

An intravascular device comprising a tube member, the tube member comprising a distal portion and a proximal portion, wherein

• the distal portion of the tube member comprises a plurality of cuts circumferentially extending around a longitudinal axis of the tube member, the plurality of cuts of the distal portion of the tube member comprising a first pitch, a first cut length, a first uncut length, and a first cut width;
• the proximal portion of the tube member comprises a plurality of cuts circumferentially extending around the longitudinal axis, the plurality of cuts of the proximal portion of the tube member comprising a second pitch, a second cut length, a second uncut length, and a second cut width;
• the first pitch is less than the second pitch, the first cut length is greater than the second cut length, the first uncut length is less than the second uncut length, and the second cut width is less than the first cut width;
• the plurality of cuts of the distal portion are helical cuts, and the plurality of cuts of the proximal portion are helical cuts;
• the first cut width ranges between 0.015 mm and 0.030 mm, the second cut width ranges between 0.010 mm and 0.025 mm;
• the first cut length ranges between 60 degrees and 177 degrees, the first uncut length ranges between 3 degrees and 15 degrees, the second cut length ranges between 60 degrees and 165 degrees, and the second uncut length ranges between 15 degrees and 40 degrees;
• and
• a combination of the first cut length and the first uncut length is greater than a combination of the second cut length and the second uncut length.
