    Abstract: Embodiments herein relate to implantable medical devices including a welded joint with reduced residual stress. In a first aspect, an implantable medical device is included having a power subunit comprising a first biocompatible electrically conductive shell, an anode disposed therein, a cathode disposed therein, and a lid. The implantable medical device can further include an electronics control subunit comprising a second biocompatible electrically conductive shell, and a control circuit disposed therein. Both of the first and second biocompatible electrically conductive shells can include first and second opposed wide sides, first and second opposed narrow sides, and four rounded corners. The first shell can be welded to the lid around a perimeter thereof forming a weld line. The weld line can have a weld line terminus and the weld line terminus can be positioned on a narrow side or a rounded corner. Other embodiments are also included herein.

    Abstract: A filtered feedthrough assembly for an implantable medical device comprises a ferrule, an electrical insulator coupled to the ferrule by a connection element, a plurality of feedthrough conductors extending through the electrical insulator, a printed circuit board (PCB), and plurality of capacitors. The PCB is coupled to the ferrule or the electrical insulator, and includes one or more ground layers and a plurality of vias. The connection element is electrically coupled to the ground layer through the vias. The capacitor has a ground terminal electrically coupled to the ground layer through at least one of the vias, and a conductor terminal electrically coupled to the feedthrough conductor.

    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.
