Abstract
A steerable guide wire for cannulation of tubular or vascular organs. The guide wire has a distal end and a proximal end. The guide wire has at least one coil forming a helix near the distal end of the guide wire to aid in the negotiation through tubular or vascular organs such as endoscopic retrograde or antegrade cannulation of the cystic duct. A removable clamp is secured to the proximal end of the guide wire to allow the user to apply torsional and longitudinal force to steer the guide wire into position.
