Abstract

L'invention concerne des ensembles-embouts de fibres, à transmission optique, dans lesquels sont incorporées des particules diffusant un rayonnement, utilisés en photothérapie. Selon une variante, l'invention concerne des diffuseurs pourvus de capuchons terminaux réfléchissants. Lorsqu'un rayonnement se propage à travers l'embout de fibre, une partie des rayons est diffusée selon une configuration cylindrique (ou partiellement cylindrique) le long de l'embout de fibre. Le rayonnement qui n'est pas diffusé pendant ce passage initial à travers l'embout peut être réfléchi par au moins une seule face de l'ensemble embout et renvoyé à travers l'embout. Pendant ce second passage, le rayonnement résiduel (ou au moins une partie importante de ce rayonnement réfléchi) rencontre de nouveau les diffuseurs qui créent une autre diffusion radiale de ce rayonnement. Le milieu de diffusion et le capuchon terminal réfléchissant peuvent interagir pour produire une répartition axiale (ou autrement prédéfinie), pratiquement uniforme, du rayonnement laser sur la longueur de l'embout qui forme l'appareil présenté. Selon une autre variante, l'invention concerne des ensembles-boucles de diffusion qui servent à diffuser une rayonnement provenant d'une fibre optique. L'invention concerne également des gaines jetables ainsi que des dispositifs d'arrêt solidaires de l'embout qui limitent la pénétration de l'appareil. Les appareils selon l'invention peuvent être utilisés à différentes fins d'ordre médical ainsi que pour stériliser des instruments médicaux.
