Stent and method of manufacturing same
First Claim
1. A stent for use in a body passageway comprising a flexible self-expanding braided tubular wall comprising helically wound wires and having proximal and distal ends, wherein the wires of the tubular wall are shaped at selected locations to form at each selected location an elevation extending radially away from the tubular wall the elevations cooperating to form a helical elevation pattern having a different pitch than the helically wound wires of the braided tubular wall.

Abstract
A prosthetic stent with a tubular wall having local inwardly or outwardly formed elevations. Stents having such elevations have a higher mechanical stability if bend according to the curvature of the body vessels to be supported or repaired. Also a method for manufacturing a stent with such elevations is described.
