Abstract

MÉTODO PARA FORMAÇÃO DE UM CONJUNTO DE MICROAGULHAS, CONJUNTO DE MICROAGULHAS MOLDADAS POR INJEÇÃO E EMPLASTRO TRANSDÉRMICO. A presente invenção descreve dispositivos moldados por injeção incluindo microagulhas em uma base de substrato. As microagulhas podem incluir uma pluralidade de estruturas nanodimensionadas fabricadas sobre elas. Os moldes usados para formar as microagulhas são montados a partir de uma pluralidade de segmentos de molde, cada um definindo porções das microagulhas. Quando da moldagem dos múltiplos segmentos de molde, são formadas cavidades negativas de microagulha. Os moldes podem ser usados em um processo de moldagem por injeção, para formar disposições de microagulhas. Os dispositivos podem ser utilizados para interação com um componente do tecido conectivo dérmico.METHOD FOR FORMING A MICRONEEDLE ASSEMBLY, INJECTION MOLDED MICRONEEDLE ASSEMBLY AND TRANSDERMAL PATCH. The present invention describes injection molded devices including microneedles in a substrate base. The microneedles can include a plurality of nanosized structures fabricated thereon. The molds used to form the microneedles are assembled from a plurality of mold segments, each defining portions of the microneedles. When molding the multiple mold segments, negative microneedle cavities are formed. The molds can be used in an injection molding process to form arrays of microneedles. The devices can be used to interact with a dermal connective tissue component.
