Abstract
The present invention relates to a medical prosthesis having a low profile for delivery into a body lumen. The stent includes a plurality of geometric cells defining the stent, which has first and second opposed open ends; and a plurality of wire strands woven to form a plurality of crossed regions defining the geometric cells. Each wire strand has strand ends and the strand ends are disposed at the second end of the stent.
