Abstract
Un extenseur compatible pour être inséré dans le corps humain est formé de multiples filaments disposés en deux ensembles d'enroulements hélicoïdaux opposés entrelacés selon une configuration tressée. Chaque filament est un matériau composite comprenant une partie centrale (24) et une enveloppe (26) entourant la partie centrale (24). Dans une version davantage préférée, la partie centrale est constituée d'un matériau radiopaque et relativement ductile, tel que le tantale ou le platine. L'enveloppe externe (26) est formée d'un matériau relativement élastique, tel qu'un alliage à base de cobalt/chrome. Les bonnes caractéristiques mécaniques de l'extenseur sont déterminées par l'enveloppe (26) alors que la partie centrale (24) permet in vivo la visualisation de l'extenseur. Les filaments composites sont obtenus par un procédé de formation de tubes, remplis, étirés dans lesquel la partie centrale (24) est insérée dans une enveloppe tubulaire (26) d'un diamètre sensiblement supérieur au diamètre final, prévu, du filament. Le filament composite est formé à froid en plusieurs étapes afin de réduire son diamètre, et recuit entre des étapes successives de formage à froid. Après l'étape de formage final, le filament composite est formé selon une configuration désirée et durci par vieillissement. D'autres matériaux composites ont une couche barrière intermédiaire (86) placée entre l'enveloppe (26) et la partie centrale (24), une couche de couverture biocompatible entourant l'enveloppe (26), et une enveloppe radiopaque (26) entourant une partie centrale structurale (24).
