RÉSEAUX SELECTIVE EN FRÉQUENCE DE COMPOSANTS PASSIFS POUR FILS IMPLANTABLES DE DISPOSITIFS MÉDICAUX IMPLANTABLES ACTIFS UTILISANT UNE SURFACE DE DISSIPATION D'ÉNERGIE
Decoupling circuits are provided which transfer energy induced from an MRI pulsed RF field to an energy dissipating surface. This is accomplished through broadband filtering or by resonant filtering. In a passive component network for an implantable leadwire of an active implantable medical device, a frequency selective energy diversion circuit is provided for diverting high-frequency energy away from a leadwire electrode to a point or an area spaced from the electrode, for dissipation of high-frequency energy.
