Abstract
(EN) A series of articles and techniques for controlled pharmaceutical delivery within a patient is described. An article includes at least one cavity having an interior dimension equal to a resonant mode of electromagnetic radiation to which the article is exposed. A standing wave is created within the cavity, causing a change in a diffusion characteristic of at least one component of the cavity, in turn causing release of a pharmaceutical from the cavity into an area of the body surrounding the article. Low-energy, non-destructive electromagnetic radiation, such as visible or near-infrared light, can be used.
(FR) L'invention concerne une série d'articles et de techniques permettant de commander l'administration d'un médicament chez un patient. Un article comprend au moins une cavité présentant une dimension intérieure égale à un mode résonnant d'un rayonnement électromagnétique auquel l'article est exposé. Une onde stationnaire est créée à l'intérieur de la cavité, provoquant un changement dans une caractéristique de diffusion d'au moins un constituant de ladite cavité, provoquant à son tour la libération d'un médicament à partir de la cavité dans une zone du corps entourant l'article. Un rayonnement électromagnétique de faible énergie, non destructif, tel qu'une lumière proche infrarouge ou une lumière visible peut être utilisé.
