Abstract
A leafless biostimulator, such as a leadless pacemaker, includes a housing sized and configured to be implanted within a heart of a patient and includes both primary and secondary fixation features. The primary fixation feature is adapted to rotate to fix the leadless biostimulator to a wall of the heart during initial implantation. Once the leadless biostimulator is implanted, the secondary fixation feature is adapted to resist counter-rotation of the leadless biostimulator. The primary fixation feature may include a fixation helix configured to affix the housing to the heart by rotating in a screwing direction. The secondary fixation feature may include an apex to engage the heart to resist unscrewing of the primary fixation feature.
