Abstract
A biostimulator, such as a leadless cardiac pacemaker, including a fixation element to engage tissue and one or more backstop elements to resist back-out from the tissue, is described. The fixation element can be mounted on a housing of the biostimulator such that a helix of the fixation element extends distally to a leading point. The leading point can be located on a distal face of the helix at a position that is proximal from a center of the distal face. The backstop elements can include non-metallic filaments, such as sutures, or can include a pinch point of the biostimulator. The backstop features can grip the tissue to prevent unscrewing of the fixation element. Other embodiments are also described and claimed.
