| 1. A guide wire comprising:
an elongate core defining a proximal end and a distal end;
a continuous, unitary coil exhibiting an outer diameter and an inner diameter surrounding a portion of the core, with a portion
of the coil extending beyond the distal end of the core by a plurality of turns of the coil, the inner diameter of the coil
defining an internal area inside the coil along the portion of the coil that extends beyond the core; and
a polymer contacting the distal end of the core and entirely filling the internal area, without extending beyond a distal
end of the coil; and
a metal tip extending from a distal end of the polymer and contacting a distal surface of the coil.
