1. A catheter comprising:
an elongated shaft having a proximal portion, a distal portion, and an intermediate portion therebetween;
wherein:
the intermediate portion has a proximal region, an overlapping region, and a distal region, the overlapping region being between the proximal region and the distal region;
the proximal region includes a polymer structure, an inner braid at least partially positioned in the polymer structure, and an outer braid surrounding at least a portion of the inner braid;
the overlapping region includes: (a) the polymer structure, (b) a coil at least partially positioned in the polymer structure, and (c) the outer braid surrounding at least a portion of the coil;
a proximal terminus of the coil is at a border between the proximal region and the overlapping region; and
a distal terminus of the outer braid is at a border between the overlapping region and the distal region.
