Abstract

L'invention concerne un microcathéter (100) pour administrer des fluides thérapeutiques à un patient, et ses procédés de fabrication et d'utilisation. Le microcathéter à barbillons comprend un tube creux (102) ayant une lumière allongée qui s'étend entre des extrémités proximale et distale du tube creux, une pluralité de barbillons (108) faisant saillie à partir du tube creux, et une pluralité d'ouvertures de sortie de fluide formées dans le tube creux qui sont en communication fluidique avec la lumière allongée. Les ouvertures de sortie de fluide sont espacées les unes des autres de façon régulière sur la longueur du tube creux. Un ancrage (112) est fixé à l'extrémité proximale du tube creux, et une aiguille chirurgicale (114) est fixée à l'extrémité distale du tube creux.
