A resorbable polymeric mesh implant whose implant configuration varies over time after implantation for use in breast reconstruction, wherein the resorbable polymeric mesh implant comprises at least a first material and a last-degraded material, wherein the last-degraded material is substantially degraded at a later point in time in the body than the first material. The modulus of elasticity of the last-degraded material is significantly lower than the modulus of elasticity of the first material. The last-degraded material has a modulus of elasticity that corresponds to an elongation of 18 to 32% when subjected to a tensile load of 16 N/cm. The resorbable polymeric mesh implant is tubular and configured to retain a breast implant.
