Implantable medical device with multi-sided header electrode

A method to provide an implantable medical device, the method comprising:

• providing a header by:
• inserting a sensing electrode and an antenna within a mold, the sensing electrode comprising a first body portion, a second body portion, and a bridge portion that mechanically and electrically connects the first and second body portions;
• flowing a dielectric material into the mold to at least partially surround the sensing electrode and the antenna and form a header body of the header upon solidification of the dielectric material, wherein the sensing electrode is inserted in the mold and the dielectric material is flowed into the mold such that the first body portion is at least partially exposed to an external environment along a first side of the header and the second body portion is at least partially exposed to the external environment along a second side of the header that is different from the first side;
• removing the header body with the sensing electrode and the antenna from the mold;
• and
• mounting the header to an end of a device housing that contains an electronics module therein.
