Medical device shaft resistant to compression and/or tension

A medical device with increased compression resistance, comprising:

• an elongate shaft having a proximal end region, a distal end region, a lumen extending therethrough, and a tension resistance member extending at least partially between the proximal end region and the distal end region of the elongate shaft;
• an exoskeleton disposed along an outer surface of the elongate shaft, the exoskeleton including a plurality of discrete segments including first segments and second segments alternating with one another and engaged with one another along rounded surfaces forming arcs having a shared center;
• and
• wherein at least one of the plurality of discrete segments is coupled to the tension resistance member,
• wherein the tension resistance member extends within and through a central lumen of at least one discrete segment of the plurality of discrete segments.
