A beam (16) is provided for intraluminal devices. The beam is defined by a first side surface and a second side surface. The first side surface (30) is tapered at a different rate than the second side surface (32). One advantage of the beam is that strain which is normally concentrated in adjacent, interconnected bends is redirected onto the length of the beam. This may increase the fatigue life of intraluminal devices or may be used to fashion new srtuctures with improved performance.

La présente invention concerne une poutre (16) destinée à des dispositifs intraluminaux. La poutre est définie par une première surface latérale et une seconde surface latérale. La première surface latérale (30) présente un rapport de décroissance différent de celui de la seconde surface latérale (32). Un avantage de la poutre est que la contrainte qui se concentre normalement dans des coudes entretoisés adjacents est redirigée sur la longueur de la poutre. Ceci peut accroître la durée de vie de dispositifs intraluminaux ou servir à façonner de nouvelles structures offrant de meilleures performances.
