Method for manufacturing implantable device header with embedded sensor and antenna

A method for manufacturing an implantable cardiac device, comprising:

• assembling a device housing having electronic components therein;
• joining a feed-through assembly to the device housing, the feed-through assembly including conductors having distal ends connected to the electronic components and having proximal ends projecting from the feed-through assembly;
• encapsulating a sensing electrode and an antenna within a non conductive header body formed from a biocompatible material, the electrode and antenna including corresponding interconnection plates, the header body including a housing mounting surface that includes at least one passage aligned with an interconnect cavity that includes the interconnection plates, the header body further including an window, opening laterally onto a side of the header body, the window exposing the interconnect cavity and interconnect regions;
• directing the proximal ends of the conductors through the passage to align with the interconnect regions;
• and
• securing the proximal ends and the interconnect regions to one another through the window.
