Abstract

L'invention concerne un procédé de formation d'une capsule de médicament destinée à un injecteur sans aiguille, selon lequel une surface d'un vide (22) de la capsule est irradiée de lumière provenant d'un laser à haute énergie (18), ce qui élimine la matière pour former un orifice de décharge dans une paroi de la capsule de médicament. Le laser fonctionne, de préférence, à une longueur d'onde située dans la plage ultraviolette du spectre, et peut, par exemple, être un laser à excimères. L'invention concerne un appareil mettant en application ce procédé.
