An apparatus for forming a gastric restriction includes an implantable band and at least one tab. In some versions, the at least one tab may serve to stabilize the apparatus as it forms a gastric restriction. In some versions, an opening may be formed in the tabs such that sutures may be used. In some versions, a tissue scaffold and/or matrix may be used on the implantable band and/or the tabs to facilitate long term support for the implantable band, such as by substantially preventing the implantable band from sliding along an axis defined by an anatomical structure about which the implantable band is wrapped.
