Title (EN) IMPLANTABLE DEVICE INCLUDING EDDY CURRENT REDUCING CAPACITOR
(FR) DISPOSITIF IMPLANTABLE COMPRENANT UN CONDENSATEUR DE RÉDUCTION DE COURANTS DE FOUCAULT
Abstract:
(EN) An implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can include one or more MRI Safe components. In an example, the implantable device includes a capacitor including a first electrode including a first slot extending from a perimeter of the first electrode to an interior of the first electrode. A second electrode is separated from the first electrode by a first distance. The second electrode includes a second slot extending from a perimeter of the second electrode to an interior of the second electrode. The first and second slots are configured to at least partially segment surface areas of the first and second electrodes, respectively, to reduce a radial current loop size in each of the first and second electrodes.
(FR) L'invention concerne un dispositif implantable, tel qu'un stimulateur cardiaque, un défibrillateur ou un autre système de gestion du rythme cardiaque, qui peut contenir un ou plusieurs composant(s) compatible(s) IRM. Dans un exemple, le dispositif implantable comprend un condensateur qui présente une première électrode comportant une première fente qui s'étend à partir d'un périmètre de la première électrode jusqu'à l'intérieur de la première électrode. Une deuxième électrode est séparée de la première électrode par une première distance. La deuxième électrode comporte une deuxième fente qui s'étend à partir d'un périmètre de la deuxième électrode jusqu'à l'intérieur de la deuxième électrode. Les première et deuxième fentes sont configurées de manière à segmenter au moins partiellement des régions de surface des première et deuxième électrodes, respectivement, de façon à réduire la taille d'une boucle de courant radiale dans chacune des première et deuxième électrodes.
