Title
(EN) CONTINUOUS ANALYTE MONITORING SYSTEM WITH MICRONEEDLE ARRAY
(FR) SYSTÈME DE SURVEILLANCE CONTINUE D'ANALYTE DOTÉ D'UN RÉSEAU DE MICRO-AIGUILLES
Abstract
(EN) Described herein are variations of an analyte monitoring system, including an analyte monitoring device. For example, an analyte monitoring device may include an implantable microneedle array for use in measuring one or more analytes (e.g., glucose), such as in a continuous manner. The microneedle array may include, for example, at least one microneedle including a tapered distal portion having an insulated distal apex, and an electrode on a surface of the tapered distal portion located proximal to the insulated distal apex. At least some of the microneedles may be electrically isolated such that one or more electrodes is individually addressable.
(FR) L'invention concerne des variations d'un système de surveillance d'analyte, comprenant un dispositif de surveillance d'analyte. Par exemple, un dispositif de surveillance d'analyte peut comprendre un réseau de micro-aiguilles implantable destiné à être utilisé pour mesurer un ou plusieurs analytes (par exemple, le glucose), par exemple de manière continue. Le réseau de micro-aiguilles peut comprendre, par exemple, au moins une micro-aiguille comprenant une partie distale effilée comportant un sommet distal isolé, et une électrode sur une surface de la partie distale effilée située à proximité du sommet distal isolé. Au moins certaines des micro-aiguilles peuvent être isolées électriquement de sorte qu'une ou plusieurs électrodes soient adressables individuellement.
