    Abstract: An endoprosthesis is made by radially expanding and axially extending a polymer tube. Next, portions of the polymer tube are removed to form an open framework of struts that define a tubular body. The tubular body has an end segment and an intermediate segment adjoining the end segment. The end segment includes a circumferential series of closed cells having a first W-shape closed cell. The intermediate segment includes a circumferential series of closed cells having a second W-shape closed cell. There are linear link struts at opposite ends of the individual first and second W-shape closed cells. The linear link struts of the first W-shape closed cell are longer than linear link struts of the second W-shape closed cell.
