1. A guidewire device including a shapeable tip, the guidewire device comprising:
a core including a proximal section and a distal section; and
a shapeable tube structure coupled to the core such that the distal section of the core passes into the tube structure, the tube structure including a first section and a second section distal to the first section,
wherein the tube structure includes a plurality of cuts extending transversely into the tube structure, each cut forming one or more beams defined by a remaining section of tube material, each beam connecting two adjacent rings of tube material,
wherein the first section of the tube structure includes two or more beams between adjacent rings and the second section of the tube structure includes a single beam between adjacent rings,
wherein a thickness of a most proximal ring of the second section is greater than a thickness of a most distal ring of the first section, and
wherein a stiffness of the tube structure is continuous across a transition between the first and second sections.
