An implantable bioabsorbable article for the separation and regeneration of tissue at a tissue defect site in the form of a fibrous matrix laminarly affixed to both surfaces of a cell-barrier sheet material. When implanted it allows ingrowth of tissue into the fibrous matrix side of the material; simultaneously the tissue to be regenerated at the tissue defect site is separated from the ingrowing tissue by the cell-barrier sheet material. A method for making the implantable bioabsorbable article is also described.
