Abstract
An expandable intraluminal vascular graft is implanted in a coronary artery or other vessel to maintain the patency of the lumen. The vascular graft, commonly referred to as a stent, expands from a first diameter to a second diameter, and a plurality of teeth are moved in relation to a longitudinal slot to lock the stent in an expanded condition.
