Implantable prostheses for reinforcing and repairing defects in a muscular or tissue wall and a method for fabricating the prostheses that minimizes wasted mesh material and reduces the labor and time required for fabrication. The prosthesis may include a plug body formed of surgical mesh material having a closed end, a larger open end, and a cavity extending therebetween, and a filler body formed of the surgical mesh material comprising a plurality of petals extending radially outwardly from and spaced laterally about a common base disposed in the plug body with the common base attached to the closed end of the plug body. The plug bodies are cut as circular pieces, and the filler bodies are cut as hour-glass shaped pieces from the same sheet of material so as to leave virtually no wasted mesh material. The filler pieces may be attached to the plug body piece by welding.

Implantable mesh prostheses and method of manufacturing same

An implantable prosthesis is provided for repairing an anatomical defect, such as a tissue or muscle defect, that promotes tissue of muscle ingrowth into the prosthesis and subsequently strengthens the area of the defect. The prosthesis is easy to manipulate and may be designed to minimize the incidence of postoperative adhesions between a portion of the prosthesis and surrounding tissue or organs. The prosthesis may include one or more layers of biologically compatible material that is suitable for repairing a defect. The prosthesis may include a support assembly to facilitate manipulation and deployment of the prosthesis. The support assembly may include a stiffening member that is surrounded by material that separates the stiffening member from the layer of material. The stiffening member may be located in a sleeve of material, such as mesh fabric. The stiffening member may be formed from a resorbable material.
