Abstract: Intravascular catheters are disclosed herein. According to some embodiments, the present technology includes a catheter comprising an elongate tubular sidewall defining a lumen extending therethrough and having a proximal end, a distal end, and a length between the proximal and distal ends. The sidewall can comprise a plurality of filaments, at least some of the filaments being interwoven with other filaments of the plurality of filaments. The catheter can be configured to be positioned around a turn in a blood vessel having a radius of curvature no greater than 24 mm, and wherein, while the distal end of the catheter is distal of the turn, the lumen remains at least 70 percent patent while torque applied to the sidewall at the proximal end of the catheter is transmitted to the distal end.
