1. A method of treating an artery, comprising the steps of:

  • accessing to the artery through a small man-made passageway;

    initially loosening plaque from the artery at a segment remote from the man-made passageway using a loosening instrument introduced through the man-made passageway;

    removing plaque from within the segment of an artery at which the loosening step took place and excising the removed plaque through the small man-made passageway using a removing instrument;

    immediately thereafter, placing a substantial exposed collapsed vascular graft carried by an insertion instrument into the artery through the small man-made passageway and displacing the vascular graft to a location within the artery co-extensive at least in part with the segment, using the insertion instrument;

    without substantial delay, causing the vascular graft to be disassociated from the insertion instrument and positioned in continuously contiguous adherence within said artery at said location.
