Title (EN) MICRONEEDLE DEVICES AND METHODS OF MANUFACTURE
(FR) DISPOSITIFS A MICRO-AIGUILLES ET PROCEDES DE PRODUCTION
Abstract: front page image
(EN)Microneedle devices and methods of manufacturing the microneedle devices. The microneedle devices include microneedles protruding from a substrate (20), with the microneedles (30) piercing a cover (40) placed over the substrate surface (22) from which the microneedles protrude. The cover (40) and the microneedle substrate (20) together define a capillary volume in fluid communication with the base (34) of each microneedle (30). One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue. Manufacturing methods may include simultaneous application of pressure and ultrasonic energy when piercing the cover with the microneedles.
(FR)L'invention concerne des dispositifs à micro-aiguilles et des procédés permettant de produire ces dispositifs. Ces dispositifs à micro-aiguilles comprennent des micro-aiguilles qui s'avancent à partir d'un substrat (20), ces micro-aiguilles (30) perforant un élément (40) de couverture superposé à la surface (22) du substrat et émergeant de celui-ci. L'élément (40) de couverture et le substrat (20) à micro-aiguilles définissent ensemble un volume capillaire en communication fluidique avec la base (34) de chaque micro-aiguille (30). Un des mode d'utilisation de ces ensembles de micro-aiguilles comprend des procédés consistant à perforer la peau pour délivrer un médicament ou d'autres produits et/ou pour prélever du sang ou des tissus. Les procédés de production peuvent comprendre l'application simultanée d'une pression et d'une énergie ultrasonore au moment de la perforation de l'élément de couverture par les micro-aiguilles.
