  • Implantable medical device with reduced stress welded joint
    Patent number: 11400301
    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.
