1. An implantable medical device comprising:
a header body defining a header bore that extends from an outer surface of the header body to an inner cavity of the header body;
a septum assembly comprising:
a retainer disposed at least partially within the header bore and defining a retainer bore, the retainer including a first welding surface that abuts a second welding surface of the header body at a joint, the first welding surface secured to the second welding surface via a weld bead along the joint to secure the retainer to the header body; and
a septum disposed at least partially within the retainer bore, the septum formed of a flexible material and defining at least one of a puncture or a slit therethrough to allow insertion of a tool through the septum into the inner cavity and to provide a seal when the tool is not inserted through the septum; and
a sealing element disposed between the retainer and the header body along the joint to seal the joint, the sealing element discrete from the septum.
