Abstract
Cette invention se rapporte à un extenseur médical tubulaire expansible pour applications endovasculaires, qui sert de dispositif de support pour les parois de passages corporels anatomiques ou de vaisseaux, cet extenseur étant expansible à l'intérieur du vaisseau grâce à un ballonnet d'angioplastie associé à un cathéter, en vue de dilater et augmenter la lumière du vaisseau. Cet extenseur comprend un système de plusieurs serpentins radialement expansibles disposés en anneaux interconnectés. Lors du gonflage du ballonnet, l'extenseur se dilate à la fois dans le sens radial et dans le sens longitudinal en fonction de l'amplitude de la force exercée par le ballonnet radialement vers l'extérieur. Cet extenseur est conçu pour que, en se dilatant, une déformation plastique locale ne se produise qu'aux points d'inflexion répartis sur tous les anneaux. La dilatation est limitée proportionnellement à l'amplitude de l'expansion, afin d'assurer que l'extenseur ainsi dilaté reste en deçà des limites de fracture du matériau et qu'une structure de support adéquate pour les parois du vaisseau soit ainsi obtenue.
