    Abstract: Embodiments herein relate to implantable chemical sensors. In an embodiment, an implantable optical chemical sensor includes a circuit board, at least one optical emitter, and at least one optical detector. The optical emitter can be disposed on the circuit board along with the optical detector. The optical chemical sensor can also include a floor plate and a well plate, the well plate defining at least one well and the well plate disposed over the floor plate. The well plate can include a vertical facet and a beveled facet disposed on a perimeter edge of the well plate. A feed-through flange can define a window with the vertical facet of the well plate fitting into the window. The optical emitter can emit light through the floor plate and into the well plate which is then redirected by the beveled facet into the well. Other embodiments are also included herein.

    Abstract: 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.

    Abstract: An implantable medical device lead includes an inner conductor coil comprising one or more generally cylindrically wound filars. The inner conductor coil is configured to have a first inductance value greater than or equal to 0.2 μH/inch when the inner conductor coil is subjected to a range of radio frequencies. The implantable medical device lead also includes a multi-filar outer coil comprising two or more generally cylindrically wound filars. The multi-filar outer coil is configured to have a second inductance value greater than or equal to 0.1 μH/inch when the multi-filar outer coil is subjected to the range of radio frequencies.
