Abstract
A radially expandable prosthesis for implantation in a lumen comprises a tubular wall having an inner surface and an outer surface. The tubular wall is provided with cuts to form solid struts which have a thickness and which enables the prosthesis to expand. The solid struts have reservoirs made therethrough in the form of perforating holes for containing a therapeutic agent. The perforating holes each have an inner opening and an outer opening of substantially the same size. The prosthesis, including said perforating holes, has a smooth electrochemically polished surface.
