Title (EN) STEERABLE MEDICAL DEVICE AND THE PREPARING METHOD THEREOF
(FR) DISPOSITIF MÉDICAL ORIENTABLE ET SON PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) A medical device includes at least one ionic electroactive polymer actuator, the actuator including at least one polymer electrolyte member defining at least a surface and a plurality of electrodes disposed about the surface of the at least one polymer electrolyte member, an elongate, flexible portion defining a proximal end and a distal end secured adjacent to the ionic electroactive polymer actuator and the elongate, flexible portion further comprising a core and a sleeve surrounding the core and a plurality of electrically-conductive wires, each having a proximal end and a distal end coupled to at least one of the plurality of electrodes, wherein the at least one polymer electrolyte member deforms asymmetrically in response to the application of an electrical potential supplied through at least one of the plurality of electrically-conductive wires to at least one of the plurality of electrodes.
(FR) Cette invention concerne un dispositif médical comprenant au moins un actionneur polymère électroactif ionique, où l'actionneur comprend au moins un élément d'électrolyte polymère définissant au moins une surface et une pluralité d'électrodes agencées autour de la surface du ou des éléments d'électrolyte polymère; une partie flexible allongée définissant une extrémité proximale et une extrémité distale fixée adjacente à l'actionneur polymère électroactif ionique, où ladite partie flexible allongée comprend en outre un cœur et un manchon entourant le cœur et une pluralité de fils électriquement conducteurs, ayant chacun une extrémité proximale et une extrémité distale couplée à au moins l'une de la pluralité d'électrodes, où le ou les éléments d'électrolyte polymère se déforment de manière asymétrique en réponse à un potentiel électrique appliqué par l'intermédiaire d'au moins l'un de la pluralité de fils électroconducteurs à au moins l'une de la pluralité d'électrodes.
