A catheter may include an inner liner (28, 68, 108), at least one support structure (36, 38, 76, 78, 116, 118) over the inner liner, and an outer jacket (32, 72, 112) over the at least one support structure. In some examples, the catheter includes a tip jacket (46, 136) positioned over a distal portion of the outer jacket and extend beyond a distal-most part of the inner liner and a distal-most part of the outer jacket to define a single-layer catheter tip. In some examples, the at least one support structure may include a braid (38, 78, 118) and a coil (36, 76, 116). The catheter may include a marker band (40, 80, 120) over a distal portion of one of the braid or the coil. The other of the braid or the coil ends proximally of a proximal end of the marker band, such that the catheter includes a location with lower radial and/or flexural stiffness proximal of the marker band.
