1. A catheter braid having a proximal portion with a proximal end and a distal portion with a distal end and extending a length, the catheter braid comprising a plurality of wire segments, each wire segment comprising:
an outer shell having a first material composition; and
an inner core extending through the outer shell and having a second material composition that is different than the first material composition over at least a portion of the length, the inner core having a first cross-section shape proximate the proximal end and a second cross-section shape proximate the distal end, the first cross-section shape transitioning to the second cross-section shape along the length;
wherein the inner core is distally followed by a cavity at the distal end of the distal portion.
