Embodiments herein relate to implantable medical devices including a power subunit with a first biocompatible electrically conductive shell configured for direct contact with an in vivo environment. In some embodiments a lithium anode can be disposed within the first biocompatible electrically conductive shell in direct electrical communication with a feedthrough pin, wherein the feedthrough pin is electrically isolated from the first biocompatible electrically conductive shell. A cathode can also be disposed within the first biocompatible electrically conductive shell and can be in direct electrical communication with the first biocompatible electrically conductive shell. The first biocompatible electrically conductive shell has a positive electrical potential. The implantable medical device further includes an electronics control subunit with a control circuit disposed within a second biocompatible electrically conductive shell. Other embodiments are included herein.

Implantable medical device with biocompatible battery shell

An example includes a capacitor case sealed to retain electrolyte, at least one anode disposed in the capacitor case, the at least one anode comprising a sintered portion disposed on a substrate, an anode conductor coupled to the substrate in electrical communication with the sintered portion, the anode conductor sealingly extending through the capacitor case to an anode terminal disposed on the exterior of the capacitor case with the anode terminal in electrical communication with the sintered portion, a second electrode disposed in the capacitor case, a separator disposed between the second electrode and the anode and a second electrode terminal disposed on an exterior of the capacitor case and in electrical communication with the second electrode, with the anode terminal and the second electrode terminal electrically isolated from one another.

Implantable energy storage device including a connection post to connect multiple electrodes

The present subject matter includes an implantable medical device with a capture feature at or near the proximal end. In some cases, the capture feature includes a hold that is configured to facilitate a releasable connection with a delivery device that is used to deliver the implantable medical device to a target implant site.

Implantable medical device with proximal capture feature

An implantable medical device (IMD) with an inductive coil for wireless communication and/or power transfer. The inductive coil may be disposed about a housing of the IMD. The housing may include a magnetically permeable material that is configured to operate as a flux concentrator for concentrating non-radiative near-field energy through the inductive coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.

Implantable medical device with a magnetically permeable housing and an inductive coil disposed about the housing

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

A method includes treating a CFx material with a base during the formation of a CFx cathode; and assembling the treated CFx material into a cathode electrode and assembling the cathode electrode with a lithium anode electrode and an electrolyte into a cell.

Method to stabilize lithium / carbon monofluoride battery during storage

This document provides an apparatus including a sintered electrode, a second electrode and a separator material arranged in a capacitive stack. A conductive interconnect couples the sintered electrode and the second electrode. Embodiments include a clip interconnect. In some embodiments, the interconnect includes a comb-shaped connector. In some embodiments, the interconnect includes a wire snaked between adjacent sintered substrates.
