2. A steerable guidewire comprising: an outer tube characterized by a proximal end, a distal end, and a flexible region at said distal end of the outer tube, said flexible region also characterized by a proximal and a distal end; and an inner tube characterized by a proximal end and a distal end, and a flexible region near said distal end of the inner tube; said inner tube being disposed within the outer tube, extending from the proximal end of the outer tube to the distal end of the outer tube, and terminating distally proximate the distal end of the outer tube, said inner tube longitudinally fixed to the outer tube at a point in the outer tube proximate the distal end of the flexible region of the outer tube; wherein the flexible region of the outer tube comprises a segment of the outer tube which is snake-cut with a plurality of radially oriented slots in a wall of the outer tube, said radially oriented slots being radially aligned along one side of the outer tube; and the flexible region of the inner tube comprises a segment of the inner tube with a longitudinally oriented slot, wherein said longitudinally oriented slot divides the flexible region of the inner tube into a first partial cylinder segment and a second partial cylinder segment; wherein the inner tube is fixed to the outer tube at a point radially aligned with the radially oriented slots.
