1. An implantable medical device (IMD), comprising:
a housing comprising an open end;
a header defining a cavity and comprising a conduit through a wall of the header, the header comprising a non-conductive material, the non-conductive material comprising a ceramic material;
a coupling member comprising a flange, wherein the flange is configured to be received by the open end of the housing and wherein the flange and the open end of the housing at least partially overlap along an axial direction of the IMD when the flange is received by the open end;
an electrode arranged on an outer surface of the header such that the electrode contacts and covers a portion of the ceramic material of the header;
a feedthrough coupled to the electrode and extending through the conduit of the header, wherein the feedthrough is configured to be coupled to internal circuitry housed within the IMD; and
a ring forming a hermetic seal between the coupling member and the header, wherein the ring is a metallic ring,
wherein the IMD does not include a feedthrough assembly positioned at the open end when the IMD is fully assembled.
