Abstract

Cette invention concerne un cathéter d'injection (10) comprenant un corps de cathéter allongé (12) et, à son extrémité distale (16) une partie d'injection qui sert à apporter du fluide thérapeutique dans les voies corporelles. Ladite partie d'injection (18) (60) comprend un tuyau externe (32) et un tuyau interne (38) concentrique au tuyau externe, chaque tuyau comportant plusieurs ouvertures (48) (50). Le tuyau interne (38) délimite une lumière centrale (42) d'apport de fluide, et est espacé de manière uniforme du tuyau externe (32) pour former un passage annulaire (46) dont la profondeur radiale est suffisante pour que le fluide puisse s'écouler. Chacune des ouvertures (50) formées dans le tuyau externe (32) permet au fluide de s'écouler entre le passage annulaire (46) et l'extérieur du cathéter, alors que chacune des ouvertures (48) formées dans le tuyau interne (38) permet au fluide de s'écouler entre la lumière centrale (42) et le passage annulaire (46). Le fluide thérapeutique peut ainsi s'écouler (52) de la lumière centrale jusqu'à l'extérieur du cathéter en passant par le passage annulaire.
