The granted patent (Publication Number: US11918820B2) discloses a header assembly for a leadless biostimulator, comprising a flange with a mounting wall having a central channel, a helix mount overmolded on the flange, a fixation helix mounted on the helix mount, and an electrode exposed through a hole in the central channel. The assembly includes features such as a threadless outer surface, a circumferential groove defining a recess, and an insulator with a sealing collar. The fixation helix revolves about the longitudinal axis and is embedded within the helix mount.

Furthermore, the patent describes a leadless biostimulator incorporating the header assembly, a housing with an electronics compartment, and an electronics assembly. The header assembly includes the flange, helix mount, fixation helix, and electrode. The inner surface of the helix mount adheres to the outer surface of the mounting wall, and the assembly features a circumferential groove defining a recess and an insulator with a sealing collar. The fixation helix revolves about the longitudinal axis and is mounted on the helix mount. The patent also outlines a method for assembling the leadless biostimulator, involving mounting an insulator, overmolding a helix mount, and mounting a fixation helix. The method includes steps such as defining a circumferential groove as a recess and mounting an electrode within the insulator channel.
