Title (EN) EXPANDABLE STENT AND METHOD FOR PRODUCTION OF SAME
(FR) PROTHESE ENDOVASCULAIRE EXTENSIBLE ET SON PROCEDE DE PRODUCTION
Abstract:
(EN) An expandable stent comprising a proximal end and a distal end in communication with one another. A tubular wall is disposed between the proximal end and the distal end. The tubular wall has a longitudinal axis and a porous surface defined by a plurality of interconnecting struts, a series of the struts connected to one another at an interconnection point. The struts are reversibly hingeable, preferably by plastic bending, at the interconnection point. The stent is expandable from a first, mechanically unstrained position to the second, expanded position upon the application of a radially outward force on the stent. Expansion of the stent may be achieved without appreciable plastic deformation of the entire stent structure. Preferably, the tubular wall has a substantially circular cross section in the first position and the second position. A process for producing the stent is also disclosed. Generally, the process comprises the step of radially compressing the stent in the second position to produce the stent in the first position.
(FR) L'invention concerne une prothèse endovasculaire extensible comprenant une extrémité proximale et une extrémité distale en communication mutuelle. Une paroi tubulaire est disposée entre l'extrémité proximale et l'extrémité distale. La paroi tubulaire présente un axe longitudinal et une surface poreuse définie par une pluralité de tiges d'interconnexion, une série de tiges connectées mutuellement au niveau d'un point d'interconnexion. Les tiges sont articulées de manière réversible, de préférence par flexion plastique, au niveau du point d'interconnexion. La prothèse endovasculaire est extensible d'une première position non contrainte mécaniquement à la seconde position déployée lors de l'application d'une force extérieure radialement sur la prothèse endovasculaire. L'extension de la prothèse endovasculaire peut être obtenue sans déformation plastique sensible de la totalité de la structure de la prothèse. La paroi tubulaire présente de préférence une section sensiblement circulaire dans la première position et dans la seconde position. L'invention concerne également un procédé de production de ladite prothèse endovasculaire. D'une manière générale, le procédé comprend l'étape de compression radiale de ladite prothèse endovasculaire dans la seconde position pour produire ladite prothèse dans la première position.
