An implantable device covers and seals an enteroatmospheric fistula or other short-tract opening in tissue and assists in healing the fistula. The implantable device may include a cap that is configured to be positioned on a first side of the tissue and to substantially cover a first opening of the short-tract fistula. The implantable device may also include an anchor member operably connected to the cap. The anchor member may be configured to be positioned on a second side of the tissue and to substantially cover a second opening of the short-tract fistula. Also, the implantable device may include a plug structure operably connected to the cap and the anchor member. The plug structure may be configured to fill the short-tract fistula.
