Summary:A leadless biostimulator, such as a leadless cardiac pacemaker, having a header assembly that includes overmolded components, is described. The header assembly includes a helix mount overmolded on a flange of an electrical feedthrough assembly. A fixation element is mounted on the helix mount. The overmolded helix mount fills a recess in an outer surface of the flange to robustly join the header assembly components. The electrical feedthrough assembly includes an electrode contained within the flange to deliver electrical impulses to a target anatomy, and an insulator that separates the electrode from the flange. The overmolded helix mount can conform or adhere to the outer surfaces of the flange and the insulator to electrically isolate the electrode from the flange. Other embodiments are also described and claimed.
