A needleless device (10) for delivery of an agent through a biological barrier, the device comprising a microimplant (12) retaining layer (13) holding at least one microimplant for delivery through the biological barrier, a microimplant driving layer including means (21) for providing a motive force to the or each microimplant, and a guide layer having at least one guide channel associated with a microimplant through which the motive force is applied to the or each microimplant, wherein, in use, activation of the microimplant driving layer causes the or each microimplant to be driven away from the retaining layer through the biological barrier.

La présente invention concerne un dispositif sans aiguille (10) pour l'administration d'un agent à travers une barrière biologique, le dispositif comprenant une couche de rétention (13) de micro-implant (12) retenant au moins un micro-implant à administrer à travers la barrière biologique, une couche d'entraînement de micro-implant comprenant un moyen (21) pour donner une force motrice au micro-implant ou à chaque micro-implant, et une couche de guidage présentant au moins un canal de guidage associé à un micro-implant à travers lequel la force motrice est appliquée au micro-implant ou à chaque micro-implant. En utilisation, l'activation de la couche d'entraînement du micro-implant entraîne le micro-implant ou chaque micro-implant de façon à l'éloigner de la couche de rétention et à le faire passer à travers la barrière biologique.
