Mesh implant for use in reconstruction of soft tissue defects

A resorbable polymeric mesh implant whose implant configuration varies over time after implantation for use in reconstruction of soft tissue defects, wherein the resorbable polymeric mesh implant comprises:

• at least a first material and a second material, wherein the second material is substantially degraded at a later point in time than the first material, wherein a modulus of elasticity of the first material includes both the modulus of elasticity of the material itself and also the elasticity due to a present structural configuration of the first material in said implant configuration, wherein a modulus of elasticity of the second material includes both the modulus of elasticity of the material itself and also the elasticity due to a present structural configuration of the second material in said implant configuration, and wherein:
• the modulus of elasticity of the mesh implant is initially substantially constant and equal to the modulus of elasticity of the first material only following a time of implantation and until said first material is substantially degraded, and wherein:
• the modulus of elasticity of the mesh implant is substantially constant and equal to the modulus of elasticity of the second material after the first material is substantially degraded and until said second material is substantially degraded, wherein the modulus of elasticity of the second material is significantly lower than the modulus of elasticity of the first material;
• wherein a last substantially degraded material has a modulus of elasticity in its configuration that is significantly lower than the modulus of elasticity of earlier degraded material during the time period when the last substantially degraded material is the only material remaining in the mesh implant, and the first material is substantially degraded at a point in time within the time range of 14-30 days following implantation,
• wherein the last substantially 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.
