Composite prosthesis, comprising a non-absorbable prosthetic fabric and at least one film made of a material which is absorbable in vivo, combined with one surface of the prosthetic fabric. In combination, the prosthetic fabric has a three-dimensional structure separating its two surfaces, at least one of which is open to all post-surgical cell colonization, and the film of absorbable material is linked at least superficially to the other surface of said fabric.

[ What is claimed is:] [1.]1. A composite prosthesis comprising:a non in vivo-absorbable prosthetic fabric having a weave or knit comprising a three-dimensional structure separating two opposite surfaces, said opposite surfaces connected to one another by connecting yarn, one of said surfaces being porous and open to post-surgical cell colonization, and the other of said surfaces being closed to said colonization;one film made of at least one polysaccharide derivative hydrogel, which is insoluble in an aqueous medium but absorbable in vivo;said film having a thickness less than a thickness of the prosthetic fabric; andsaid film being linked directly to constituent yarns of the prosthetic fabric by capillary absorption of the polysaccharide derivative in a depth of said prosthetic fabric and into said constituent yarns.
