Intraluminar perforated radially expandable drug delivery prosthesis and a method for the production thereof (Patent No.: US 8,267,991 B2)

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 there-through 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.United States Patent No: US 8,267,991 B2status: publishe
