A system for treating pelvic organ prolapse includes a hollow shell, a net, and an anchor strap. The hollow shell has an apex, with an exterior surface of the apex shaped to conform to an interior apical portion of a vagina, and the apex includes a hole. The net is associated with the apex of the hollow shell such that the net is insertable inside the vagina and conformable with the interior apical portion of the vagina. The anchor strap has a length that configures a proximal portion of the anchor strap to be attachable to the hole in the apex of the hollow shell and a distal portion of the anchor strap to be attachable to a sacrum of a patient.
