Abstract

A laser cut stent for transluminal delivery has windows in its cylindrical wall, the windows giving the stent enhanced flexibility during delivery along said lumen. A method of making such a stent involves removing from the wall of a tube enough material to leave the tube wall penetrated in a multiplicity of separate cut lines, in a pattern which permits the tube to expand. The tube is then expanded and then a plurality of tube wall scrap portions are removed from the tube wall between adjacent cut lines, thereby to introduce a plurality of spacings between adjacent stenting zones of the tube wall surface, these remaining after compression of the tube to a configuration to allow it to be advanced along a tortuous bodily lumen. Advantageously, the material of the tube is a shape memory alloy and the tube is for a self-expanding stent.
