Extendible Stent Apparatus

Abstract

An expandable stent includes a tubular structure with an outer surface positionable adjacent to a vessel wall and an inner surface facing a lumen of a body passageway. The tubular structure further includes a plurality of expansion struts, connector struts and cells. The tubular structure has a first diameter which permits intraluminal delivery of the tubular structure into the body passageway, and a second expanded and deformed diameter which is achieved upon the application of a radially, outwardly extending force. A plurality of cavities are formed in the outer surface of the stent.

1 . A method of manufacturing a stent comprising:
 providing a stent body; and   removing material from the stent body by one of mechanical, photochemical, laser, and EDM to form a plurality of irregularly shape holes.
