A biostimulator, such as a leadless pacemaker, including a header assembly having an electrical feedthrough assembly incorporating a helix mount, is described. The header assembly includes a fixation element mounted on the helix mount. The helix mount is mounted on a flange of the electrical feedthrough assembly, and thus, the fixation element can attach the leadless biostimulator to a target tissue. An electrode of the electrical feedthrough assembly is mounted within the flange to deliver a pacing impulse to the target tissue. A ceramic portion of the helix mount is disposed between the flange and the electrode to block an electrical path between the electrode and the flange. Accordingly, the helix mount both retains the fixation element on the leadless biostimulator and electrically isolates the flange and electrode components of the electrical feedthrough. Other embodiments are also described and claimed.

A biostimulator, such as a leadless cardiac pacemaker, having a header assembly that includes an antenna, is described. The antenna can be integrated into an insulator that separates an electrode of the header assembly from a flange of the header assembly. The antenna includes an antenna loop embedded in a ceramic material of the insulator. The antenna loop is located distal to the flange to reduce the likelihood of signal interference and increase communication range of the antenna. The header assembly is mounted on a housing have an electronics compartment, and an antenna lead extends from the antenna loop to electronic circuitry contained within the electronics compartment. Other embodiments are also described and claimed.
