Abstract

L'invention concerne un appareil à pointe de cathéter disposé dans un cathéter aux fins d'administration et de recueil d'un signal d'énergie, de manière à analyser et/ou traiter un tissu d'un corps, au moyen du signal d'énergie. L'appareil comprend un boîtier allongé (120) présentant une pluralité de rainures allongées disposées de manière annulaire sur celui-ci (124); et une fibre souple porteuse d'énergie (130) disposée dans chaque rainure allongée (124). Chaque fibre (130) comprend une extrémité proximale en communication avec une source d'énergie (133) ou un centre d'analyse de signaux (137). Chaque fibre comprend également une extrémité distale en communication avec un réflecteur (140), aux fins d'analyse et traitement du tissu du corps dans lequel le cathéter est disposé.
