Abstract: 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.

Abstract: 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.

Abstract: This disclosure relates to methods and apparatus for enhanced dielectric properties for electrolytic capacitors to store energy in an implantable medical device. One aspect of the present subject matter includes a method for manufacturing a capacitor adapted to be disposed in an implantable device housing. An embodiment of the method includes providing a dielectric comprising aluminum oxide and doping the aluminum oxide with an oxide having a dielectric constant greater than aluminum oxide. Doping the aluminum oxide includes using sol-gel based chemistry, electrodeposition or atomic layer deposition (ALD) in various embodiments.
