The guidewire extension system includes an extension guidewire adapted to be releasably but firmly connected to the proximal end of an initial guidewire. The extension guidewire has a distal end and a proximal end, and the system further comprises a connecting assembly which is mounted at the distal end of the extension guidewire, which includes a coiled spring constructed and arranged to receive and grippingly engage and lock against a distal end of the initial guidewire, and which includes a swivel joint for minimizing, if not eliminating, twisting of the extension guidewire when disconnecting the extension guidewire from the initial guidewire.
