Abstract: A surgical prosthesis for repairing a hernia in a sturdy tension-free manner. The prosthesis includes a layer of adhesion resistant material and a first layer of tissue ingrowth receptive mesh material affixed to the layer of adhesion resistant material. A second layer of tissue ingrowth receptive mesh material is positioned adjacent the first layer of tissue ingrowth receptive mesh material and a connecting thread is interwoven between the midsections of the layers for forming a midsectional seam fastening together the three layers. The prosthesis is implanted in the hernial area of the patient in such a manner as to duplicate the structure of the original unherniated fascial tissue. The adhesion resistant layer faces inwardly to prevent adhesion of internal body viscera to the prosthesis.
