An expandable stent and stent graft having a small initial diameter, flexibility along its longitudinal axis prior to expansion and a large expanded and rigid Local strain on the stent material is minimized, as and after the balloon is expanded. More particularly, the stent has rotation joints having minimal strain during stent expansion. The stent is substantially the same length before and after expansion and being flexible longitudinally when constrained, it is easy to locate. A method of manufacturing stents is described comprising rotation of a tube beneath a moving fil, with light passing through the film onto the tube, at selected locations. A laser scanning system for stent manufacture is also disclosed.

L'invention concerne un extenseur expansible et une greffe d'extenseur présentant un faible diamètre initial, une flexibilité le long de leur axe longitudinal avant l'expansion, et permettant de réduire les importantes contraintes locales d'expansion et de rigidité au moment de l'expansion du ballonnet et après celle-ci. En particulier, l'extenseur comporte des articulations rotatives subissant une contrainte minimale pendant l'expansion de l'extenseur. L'extenseur présente pratiquement la même longueur avant et après l'expansion et il est facile à localiser car il est flexible longitudinalement lorsqu'il est soumis à une contrainte. L'invention concerne également un procédé de production d'extenseurs, consistant à faire tourner un tube sous un film en mouvement, la lumière passant à travers le film pour venir en contact avec le film, en des points sélectionnés. L'invention concerne en outre un système de balayage à laser pour la production d'extenseurs.
