Abstract

L'invention concerne un système de cathéter (100) permettant de traiter un site de traitement (106) à l'intérieur ou à proximité d'un vaisseau sanguin (108) et comprenant une source de puissance (124), un guide lumineux (122) et une cible de plasma (242). Selon divers modes de réalisation, le guide lumineux (122) reçoit de la puissance provenant de la source de puissance (124). Le guide lumineux (122) comporte une pointe distale (244) et le guide lumineux (122) émet de l'énergie lumineuse (243) selon une direction d'éloignement de la pointe distale (244). La cible de plasma (242) est espacée de la pointe distale (244) du guide lumineux (122) d'une distance cible d'espace (245). La cible de plasma (242) est conçue pour recevoir de l'énergie lumineuse (243) du guide lumineux (122) pour qu'une bulle de plasma (234) soit générée au niveau de la cible de plasma (242). La source de puissance (124) peut être un laser et le guide lumineux (122) une fibre optique. Selon certains modes de réalisation, le système de cathéter (100) peut également comprendre un ballonnet gonflable (104) encerclant la pointe distale (244) du guide lumineux (122). La cible de plasma (242) peut être positionnée à l'intérieur du ballonnet gonflable (104). La distance cible d'espace (245) peut être supérieure à 1 µm. La cible de plasma (242) peut avoir une face cible (1672) qui reçoit l'énergie lumineuse (243) du guide lumineux (122). La face cible (1672) peut être inclinée par rapport à une direction dans laquelle l'énergie lumineuse (243) est émise vers la cible de plasma (242). La cible de plasma (242) peut être formée d'un ou de plusieurs éléments parmi le tungstène, le tantale, le platine, le molybdène, le niobium, l'iridium, l'oxyde de magnésium, l'oxyde de béryllium, le carbure de tungstène, le nitrure de titane, le carbonitrure de titane et le carbure de titane.
