Abstract

The present invention is a multi-cell stent having at least two different types of cells with each type of cell accomplishing a different purpose. For example, a first type of cell is intended to provide a maximum radial rigidity after stent deployment. A second type of cell is designed to provide increased longitudinal flexibility prior to stent deployment and after stent deployment into a main artery, the second type of cell can be readily balloon expanded at the ostium of a side branch artery to a comparatively large diameter without breaking any of the struts of the scent cell. By this technique, unobstructed blood flow into the side branch can be provided.
