Abstract
La présente invention concerne des micro-aiguilles (32) micro-usinées sur une surface, réalisées sous forme d'aiguilles prises une à une (32) ou montées en matrices bidimensionnelles ou tridimensionnelles (30). Ces micro-aiguilles (32) sont fabriquées sur un substrat (12) qui peut rester solidaire des micro-aiguilles (32) ou peut en être séparé ultérieurement. Ces matrices bidimensionnelles ou tridimensionnelles de micro-aiguilles (30) peuvent comporter des canaux d'écoulement à couplage croisé (36) qui assurent un équilibrage des pressions et de l'écoulement du fluide dans les matrices de micro-aiguilles (30). Chaque micro-aiguille (32) est traversée d'un micro-canal (36) qui met en communication au moins un orifice d'entrée (37) à l'extrémité proximale des micro-aiguilles (32), et au moins un orifice de sortie (39), de l'autre côté, à l'extrémité distale.
