Abstract
Disclosed is the automated rapid advancement of a guide wire through a guide catheter using x-ray markers. The procedure involves providing a guide wire with a marker at or adjacent its tip, providing a guide catheter with a marker at or adjacent its distal terminus, rapidly advancing the guide wire through the guide catheter from its proximal end to its distal end under the control of an automated apparatus, and terminating the automated rapid advancement when the guide wire tip marker becomes adjacent to the guide catheter distal end marker. Fluoroscopic images may be taken of the of the guide wire as it rapidly advances through the guide catheter and image processing software used to determine when to terminate the rapid advancement. This software may use either the position or the velocity of the guide wire to make this determination.
