ABSTRACT:
In accordance with the present invention, there is provided a guidewire extension system which easily connects and disconnects the wires. The system includes a guidewire and an extension wire. Each wire has distal and proximal ends and a longitudinal axis therebetween. The distal end of the extension wire adapted to be releasably connected to the proximal end of said guidewire or vise-versa). The system further has a coiled spring mounted the distal end of the extension wire. The spring is adapted to receive the proximal end of the guidewire so that as the wires are puled apart, the spring constricts and grips the guidewire. Lastly, the system includes a tube disposed over the coiled spring. The tube is attached to the extension wire so that it slides along its longitudinal axis. The tube is adapted to engage and expand the spring as it is slid open, towards said proximal end of the extension wire, thereby releasing the guidewire wire.
