Title (EN) MICRONEEDLES MADE FROM POLYCARBONATE-POLYCARBONATE/POLYSILOXANE COPOLYMER COMPOSITIONS
(FR) MICRO-AIGUILLES FABRIQUÉES À PARTIR DE COMPOSITIONS EN COPOLYMÈRE DE POLYCARBONATE-POLYCARBONATE/POLYLISOXANE
Abstract:
(EN) A microneedle comprising a shaft has a proximal end and a distal end and, optionally, a capillary space within said shaft, said capillary space (i) connecting said proximal and distal ends or (ii) extending from the distal end of the shaft and connecting with one or more external openings positioned between the proximal end and distal end or (iii) performing the functions of both (i) and (ii). The microneedle includes a polymer mixture that includes (a) polycarbonate, (b) polycarbonate-polysiloxane copolymer and (c) mold release agent.
(FR) L'invention concerne une micro-aiguille comprenant une tige ayant une extrémité proximale et une extrémité distale et, facultativement, un espace capillaire à l'intérieur de ladite tige, l'espace capillaire (i) reliant les extrémités proximale et distale ou (ii) s'étendant à partir de l'extrémité distale de la tige et étant relié à une ou plusieurs ouvertures externes positionnées entre l'extrémité proximale et l'extrémité distale ou (iii) réalisant à la fois les fonctions (i) et (ii). La micro-aiguille comprend un mélange de polymères qui comprend (a) du polycarbonate, (b) un copolymère de polycarbonate-polysiloxane et (c) un agent de démoulage.
