Mesh implant for use in reconstruction of soft tissue defects
The present invention relates to a resorbable polymeric mesh implant, that is intended to be used in the reconstruction of soft tissue defects. The mesh implant comprises at least a first and a second material, wherein the second material is substantially degraded at a later point in time than the first material following the time of implantation. The mesh implant is adapted to have a predetermined modulus of elasticity that gradually is decreased until the mesh implant is completely degraded and subsequently resorbed. Due to the gradual decrease in the modulus of elasticity of the inventive mesh implant, the regenerating tissue may gradually take over the load applied to the tissue defect area.
