This invention is an infusion catheter (10) including an elongated catheter body (12), and an infusion section (18) at its distal end (16) for delivery of therapeutic fluid to bodily passages. The infusion section (18, 60) includes an outer tube (32) and an inner tube (38) concentric with the outer tube, each tube having a multiplicity of ports (48, 50) there through. The inner tube (38) delimits a central, fluid delivery lumen (42). The inner tube (38) is uniformly spaced apart from the outer tube (32) to provide an annular passageway (46), the radial depth (44) of the passageway being sufficient to permit fluid flow there within. Each of the ports (50) through the outer tube (32) provides fluid between the annular passageway (46) and the exterior of the catheter, while each of the ports (48) through the inner tube (38) provides fluid between the central lumen (42) and the annular passageway (46). Thus, therapeutic fluid can flow (52) from the central lumen through the annular passageway to the catheter exterior.

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.
