Title
(EN) MICRODEVICE AND METHOD OF MANUFACTURING A MICRODEVICE
(FR) MICRODISPOSITIF ET PROCEDE DE FABRICATION DE CELUI-CI
Abstract
(EN) A device for monitoring, sampling or delivering a substance though the skin of a patient includes a support and a microdevice having at least one skin penetrating member. The support has a substantially flat bottom surface with the skin penetrating member extending beyond the bottom surface. An outlet port extends through the support to the bottom surface at a location between the skin penetrating member and the outer edge of the support for drawing a vacuum to enhance penetration of the skin. The device is produced by positioning the microdevice in a recess formed in the support and applying a bonding agent to wick into a gap formed between the microdevice and the wall of the recess.
(FR) La présente invention concerne un dispositif permettant de surveiller, d'échantillonner ou d'apporter une substance à travers la peau d'un patient. Ce dispositif comprend un support et un microdispositif possédant au moins un élément pénétrant dans la peau. Le support possède une surface de fond sensiblement plate avec l'élément pénétrant dans la peau qui se prolonge au delà de cette surface de fond. Un orifice de sortie se prolonge à travers le support vers la surface de fond, à un endroit situé entre l'élément pénétrant dans la peau et le bord extérieur de ce support, permettant de canaliser une aspiration destinée à améliorer la pénétration de la peau. Ce dispositif est produit par positionnement du microdispositif dans un retrait formé dans le support et par application d'un agent de liaison destiné à former un cordon dans un vide laissé entre le microdispositif et la paroi de ce retrait.
