A preferred embodiment of a stent provides a folded strut section that provides
both structural rigidity and reduction in foreshortening of the stent mechanism.
A flexible section provides flexibility for delivery of the stent mechanism. In
a second embodiment, flexible section columns are angled with respect to each other,
and to the longitudinal axis of the stent. These relatively flexible sections are
oppositely phased in order to negate any torsion along their length. In yet another
embodiment, the flexible connector can take on an undulating shape (like an "N"),
but such that the longitudinal axis of the connector is not parallel with the longitudinal
axis of the stent. Finally, a new method is disclosed for making stents. The method
consists of performing a standard photochemical machining process of cutting, cleaning
and coating the tube with a photoresist. However, unlike former methods, the photoresist
image is developed on the surface of the cylindrical metallic tube, which results
in a controlled variable etching rate at selected sites on the cylindrical metallic
tube during the etching process. Further embodiments provide living hinge connectors
and connections along the length of the radial strut member.
