Abstract
Pointe flexible (10), destinée à un cathéter à usage médical, apte à transmettre la lumière et dont les dimensions lui permettent de passer à travers des éléments tubulaires extrêmement petits. La pointe flexible, qui est de préférence composée d'un élastomère en silicone transparent (13), est fixée à l'extrémité d'une fibre optique classique. Selon un mode préféré de réalisation, la pointe comprend une âme (11) en silicone, entourée d'une gaine (12) dont l'indice de réfraction est inférieure à celle de l'âme (11), permettant ainsi une réflexion interne. La pointe flexible est pourvue d'une enveloppe externe (13) qui a deux fonctions: (a) elle confère une intégrité structurale à la pointe; et (b) elle sert à renforcer la liaison entre la pointe flexible et la fibre optique contre laquelle elle vient en butée. La pointe (10) permet d'apporter une intensité de lumière comparable à celle d'une fibre de verre de grande dimension et d'un diamètre d'âme équivalent mais présente une flexibilité supérieure par rapport à une telle fibre. Elle est ainsi suffisamment flexible pour pénétrer dans des éléments tubulaires sinueux tout en retenant les aptitudes de transmission de lumière des guides d'ondes optiques en fibre de verre relativement peu flexibles et de même diamètre.
