Title
(EN) DEVICE FOR THE CONTROLLED RELEASE OF A SUBSTANCE
(FR) APPAREIL POUR LA LIBÉRATION CONTRÔLÉE D'UNE SUBSTANCE
Abstract
(EN) An implantable drug delivery system is proposed which does not need internal electronics, but can be activated from outside the body. The system comprises a device (10) for the controlled release of a substance, the device (10) comprising at least one compartment (20) in a substrate (1 1), the compartment (20) being closed by a valve (30), wherein the valve is openable and comprises at least a first material (3 1) and a second material (32)., the opening and/or closing of the valve (30) being provided upon heating and/or cooling of the first and/or second material (31, 32), the first material (31) being heated by electromagnetic induction.
(FR) L'invention concerne un système d'administration de médicament implantable qui ne nécessite pas d'électronique interne, mais peut être activé depuis l'extérieur du corps. Le système comprend un dispositif (10) pour la libération contrôlée d'une substance. Ce dispositif (10) comprend au moins un compartiment (20) logé dans un substrat (11), ce compartiment (20) étant fermé par une vanne (30). Cette vanne peut être ouverte et est constituée d'un premier matériau (31) et d'un second matériau (32). L'ouverture et/ou la fermeture de la vanne (30) se fait par chauffage et/ou par refroidissement du premier et/ou du second matériau (31, 32), le premier matériau (31) étant chauffé par induction électromagnétique.
