An implantable apparatus and related methods for placement of a sling so as to provide a controllable restriction about a body lumen for restoring controlled fecal continence. The sling is generally inserted through the use of a tunneler for defining tunnels in which the sling may be inserted to provide control of the sphincter. The tunneler can be provided individually or as a set or kit of tunnelers having unique cross-sectional areas such that the size of the tunnels can be increased to accommodated insertion of the sling. The tunneler can include a self-expandable device, which can be adjusted or controlled to create a wider tunnel. The tunneler can include a semi-rigid case or sheet is disposed about the middle part of the sling to protect the mesh, make tissue penetrator easier and allow for adjustment of the mesh following insertion.
