Title
(EN) MICROJECT DEVICES AND METHODS FOR DRUG DELIVERY
(FR) DISPOSITIFS A MICROBUSE ET METHODES D'ADMINISTRATION DE MEDICAMENTS
Abstract
(EN)
A fluid delivery system includes a reservoir, a delivery actuator, and at least one delivery nozzle of a microjet having an exit orifice with a diameter between about lμm and about 500 μm. The delivery actuator may be configured to deliver a quantity of fluid contained in the reservoir into tissue of an individual through the nozzle or nozzles at a pre-determined velocity, and to desired depths. The quantity of fluid may contain one or more therapeutic agents, such as medications, drugs, bio-reactive agents, etc. The delivery actuator may also be configured to repeatedly deliver a quantity of the fluid contained in the reservoir through the at least one delivery nozzle at pre-determined intervals.
(FR)
Système d'administration de liquides comprenant un réservoir, un actionneur et au moins une microbuse dont le diamètre de l'orifice de sortie est compris entre 1 µm et 500 µm environ. L'actionneur peut être conçu pour injecter dans les tissus d'un individu un volume de liquide contenu dans le réservoir via une buse ou des buses à une vitesse prédéterminée et au profondeurs souhaitées. Le volume de liquide peut contenir un ou plusieurs agents thérapeutiques tels que des médicaments divers ou des agents bio-réactifs. L'actionneur peut également être conçu pour injecter par au moins une buse un volume de liquide contenu dans le réservoir à des intervalles prédéterminés.
