Abstract
An implant and a process for preparing such an implant are disclosed. The implant includes a porous layer including collagen, a non-porous layer including a collagenic constituent, and a reinforcement component. The non-porous layer is joined to the porous layer and the reinforcement member is embedded into the non-porous layer. The porous layer has a three dimensional density ranging from about 20 mg collagen/cm3 to about 200 mg collagen/cm3.

A process for preparing an implant having a porous layer, a non-porous layer and a reinforcement member comprising:
- preparing a composition comprising collagen, using purified fibers of collagen as starting material;
- freeze drying the prepared composition to obtain a porous layer,
- compressing the porous layer to obtain a three dimensional density ranging from about 20 mg collagen/cm3 to about 200 mg collagen/cm3;
- pouring a solution of a collagenic constituent onto a support to obtain a non-porous layer;
- applying a reinforcement member on a top surface of the non-porous layer, and
- applying the compressed porous layer on the top surface of the non-porous layer, during gelification of the non-porous layer.
