Abstract
A method and apparatus for a guide wire extension docking system for angioplasty including a guide wire and an extension wire to facilitate exchanging a balloon dilatation catheter comprising a guide wire having a proximal end and a distal end, an extension wire having a proximal end and a distal end, a hypotube having a proximal end, a distal end, an inner diameter and an outer diameter, the outer diameter of the hypotube being equal to the diameter of the extension wire, the proximal end of the hypotube being permanently affixed to the distal end of the extension wire, the distal end of the hypotube having a tongue extending distally and a spring coil with a proximal end, a distal end, an inner diameter and an outer diameter, the outer diameter of the spring coil being equal to the outer diameter of the hypotube, the spring coil having a length approximately twice the length of the tongue, the outer diameter of the spring coil being permanently affixed to the tongue such that the proximal end of the spring coil is adjacent to and axially aligned with the distal end of the hypotube, the inner diameter of the spring coil being dimensioned to slidably fit the proximal end of the guide wire with a frictional fit such that when the guide wire is inserted into the distal end of the spring coil, the guide wire is held in place by frictional engagement with the spring coil.
