Patent number: 10682522Abstract: 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.Type: GrantFiled: January 22, 2019Date of Patent: June 16, 2020Assignee: Cardiac Pacemakers, Inc.Inventors: Michael J. Lyden, Michael J. Root, Kurt E. Koshiol, Lisa B. Schmalhurst, Yingbo Li, Masoud Ameri
