CA 2464483

A transdermal transport device (10) includes a reservoir (46) for holding a formulation of an active principle, and an array of needles (12) which have bores in fluid communication with the reservoir to facilitate transporting the formulation to and from the reservoir through the needles. The device also includes a first actuator (24) which drives the array of needles into the body, and a second actuator (38) which pumps the formulation between the reservoir and the body through the needles. The first actuator is reversible to withdraw the needles from the body.

L'invention concerne un dispositif de transport transdermique (10) comprenant un réservoir (46), destiné à contenir une formulation d'un principe actif, et un réseau d'aiguilles (12) dont les alésages communiquent par fluide avec le réservoir afin de faciliter le transport de la formulation vers et depuis le réservoir à travers les aiguilles. Ce dispositif comprend aussi un premier actionneur (24), qui permet d'entraîner le réseau d'aiguilles dans le corps, et un second actionneur (38) permettant de pomper la formulation entre le réservoir et le corps via les aiguilles. Le premier actionneur est réversible, ce qui permet de retirer les aiguilles du corps.
