A surgical mesh for prolapse repair is anchored into the anterior longitudinal ligament of the sacrum and then adjusted. On the sacral end of the mesh, synthetic anchors are placed into the anterior longitudinal ligament of the sacrum. Once the anchors are placed, the mesh that is placed through the anchors can be adjusted based on the need of prolapse repair. Once adjusted, the mesh would be locked into place with a locking peg. The mesh takes the suturing away from the most critical part of the procedure, thereby enhancing safety and improving operative times. Conventional mesh do not include such a sacral anchoring system and has no way to be adjusted after placement.
