Tissue Reconstruction Devices and Methods

The present invention provides an implantable prosthesis comprising a viscera separating barrier that defines a shell having a pocket with an opening that receives an insert. It is contemplated that the insert comprises at least one of an absorbable mesh, a non-absorbable mesh, or an absorbable and non-absorbable mesh combination inserted into the pocket through the opening. In preferred embodiments the viscera separating barrier is acellular collagen, and the absorbable mesh is selected from at least one of a polyglactin, a polyglycolic acid, a polyglactin and a polylactic acid, and the non-absorbable mesh comprises a polypropylene mesh. It is contemplated that the viscera separating barrier acts to reduce or even eliminate attachment of viscera to the prosthesis to encourage rapid cell penetration and revascularization; the non-absorbable mesh will provide immediate, reliable in-growth; and the absorbable mesh will give stability to the prosthesis.
