Abstract

L'invention concerne des feuilles, fils, et tubes sans joint, métalliques, possédant une résistance mécanique accrue. Par comparaison avec des matériaux forgés réalisés dans un seul métal ou dans un alliage, les matériaux de l'invention sont constitués d'au moins deux couches formant une structure stratifiée. Les structures stratifiées sont connues pour augmenter la résistance mécanique de matériaux en feuille, tels que des produits en bois ou en papier, et sont utilisées dans le domaine des films minces pour augmenter la dureté des films de même que la résistance de ceux-ci. Des feuilles métalliques stratifiées n'ont encore jamais été utilisées ni mises au point, étant donné que les techniques de formation classiques de métaux, comme le laminage et l'extrusion, par exemple, ne permettent pas de produire des structures stratifiées. Il est possible de mettre au point des techniques de dépôt sous vide, pour produire des structures métalliques stratifiées possédant des propriétés mécaniques améliorées. En outre, il est possible de concevoir des structures stratifiées pour obtenir des qualités particulières, en ajoutant des couches possédant des propriétés spéciales, telles qu'une très grande élasticité, une mémoire de forme, une radio-opacité, une résistance à la corrosion, etc. Des exemples d'articles que l'on peut fabriquer au moyen des structures stratifiées de l'invention comprennent des dispositifs médicaux implantables, que l'on fabrique à partir de films déposés et stratifiés, dont la surface de contact avec le sang ou les tissus ou fluides corporels possède des hétérogénéités régulées dans la constitution des matériaux. L'invention concerne une greffe/extenseur et un extenseur/treillis, endoluminaux, fabriqués dans un matériau pelliculaire stratifié, déposé et gravé dans des régions d'éléments structurels et des régions de treillis sous-tendant des régions interstitielles entre les éléments structurels. L'invention concerne encore une greffe endoluminale réalisée dans un métal biocompatible ou un matériau de type métallique, biocompatible. L'extenseur/greffe endoluminal est caractérisé en ce que son matériau d'extenseur, situé le long de la surface de l'écoulement sanguin, possède des hétérogénéités régulées, et en ce que l'on utilise des procédés de dépôt sous vide pour fabriquer cet extenseur.
