摘要：
Disclosed embodiments include flexible tube assemblies, flexible needle assemblies, systems, methods of fabricating a flexible tube, and methods of fabricating a flexible needle. In an illustrative, non-limiting embodiment, a flexible tube assembly includes: a flexible tube having a proximal end with a proximal strain relief section and a distal end with a distal strain relief section, the proximal strain relief section being located between the proximal end and the distal strain relief section and the distal strain relief section being located between the distal end and the proximal strain relief section, the distal end defining an opening therein, at least a portion of at least one of the proximal strain relief section and the distal strain relief section defining therein a spiral cut with a continuously variable pitch； and tubing disposed in an airtight manner over an exterior surface of the flexible tube at least the portion of the at least one of the proximal strain relief section and the distal strain relief section defining therein the spiral cut with a continuously variable pitch.
