Mesh implant for use in reconstruction of soft tissue defects
First Claim
1. A resorbable polymeric mesh implant for use in reconstruction of soft tissue defects, wherein the 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 characterized in thatthe modulus of elasticity of the mesh implant is substantially constant and equal to the modulus of elasticity of the first material following the time of implantation and until said first material is substantially degraded, and in thatthe modulus of elasticity of the mesh implant is substantially equal to the second material after the first material is substantially degraded, wherein the modulus of elasticity of the second material is lower than the modulus of elasticity of the first material and wherein the first substantially degraded material is substantially degraded at a point in time within the time range of 2-13 days following implantation.

Abstract
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.
