1. A guidewire, comprising:
- a core wire having a distal portion;
a non-coiled tubular member disposed over the distal portion, the tubular member having a plurality of slots formed therein; and
a polymeric member disposed along an outer surface of the tubular member, the polymeric member having an uneven outer surface with a profile that is independent of a profile of the outer surface of the tubular member and independent of a profile of the core wire.

18. A guidewire having an atraumatic distal tip, comprising:
-
a core wire having a distal portion; a polymer member disposed over the distal portion; wherein the polymer member includes a polymer doped with a radiopaque material; wherein the polymer member forms a distal tip for the guidewire; wherein the distal tip has an uneven outer surface; a non-coiled nickel-titanium alloy tubular member disposed over the distal portion of the core wire, the tubular member having a plurality of slots formed therein; wherein the tubular member includes a longitudinal axis; wherein the plurality of slots includes at least one pair of opposed slots arranged on opposite sides of the longitudinal axis; and wherein at least a portion of the polymer member is disposed along an exterior surface of the tubular member and the uneven outer surface includes a plurality of ribs that are offset from the plurality of slots.
