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 battery including a first electrode and a second electrode separate from the first electrode. The second electrode includes a first surface and a second surface. The second electrode includes a slot through the second electrode from the first surface toward the second surface. The slot extends from a perimeter of the second electrode to an interior of the second electrode. The slot is configured to at least partially segment a surface area of the second electrode to reduce a radial current loop size in the second electrode.

Implantable medical device including eddy current reducing battery

One example includes a battery case sealed to retain electrolyte, an electrode disposed in the battery case, the electrode comprising a current collector formed of a framework defining open areas disposed along three axes ('framework'), the framework electrically conductive, with active material disposed in the open areas; a conductor electrically coupled to the electrode and sealingly extending through the battery case to a terminal disposed on an exterior of the battery case, a further electrode disposed in the battery case, a separator disposed between the electrode and the further electrode and a further terminal disposed on the exterior of the battery case and in electrical communication with the further electrode, with the terminal and the further terminal electrically isolated from one another.

Carbon monofluoride impregnated current collector including a 3D framework

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.
