ABSTRACT:
A guidewire and catheter are adapted for advancement through tight or tortuous vascular anatomy by providing detachably connectible threaded elements at the distal ends of each of the catheter and guidewire. When threaded together, the combined catheter and guidewire provide enhanced column strength to facilitate pushing the two together through the vascular anatomy. Alternately, the guidewire may be rotated in a manner that draws the catheter in screw-like fashion in a distal direction.
