Abstract
A soft tissue prosthesis for repairing a defect of an abdominal wall or a pelvic cavity wall, comprising: a three-dimensional mesh sheet comprising at least two types of yarn interlooped or intertwined to define at least two layers, wherein one of the at least two layers is substantially non-biodegradable and porous to allow for tissue ingrowth and another of the at least two layers is substantially biodegradable; and an adhesion barrier in the form of a film, foam or gel, the adhesion barrier polymerized to, and entrapping therein, at least some of the yarns of the substantially biodegradable layer, the substantially biodegradable layer making a connection between the adhesion barrier and the substantially non-biodegradable layer to decrease the likelihood of delamination therefrom, the adhesion barrier being an external layer on a first side of the prosthesis and the substantially non-biodegradable layer being an external layer on the side of the prosthesis opposite the first side, the substantially biodegradable layer being positioned between the substantially non-biodegradable layer and the adhesion barrier.
