Implant Device
First Claim
1. An implant device comprising a body having a stiffness gradient with at least one minimum along the x-axis and/or along the y-axis, wherein the body has a limited dimensional deformation in the direction of the x-axis and/or y-axis under maximum physiological load condition, and wherein the relative dimensional deformation is below 10% in the direction corresponding to the x- and/or y-axis, based on the dimension under no load condition compared to the dimension under a maximum load condition.

Abstract
The present invention is directed to an implant device, in particular an implant device placed between bony, cartilaginous or soft tissues or between prosthetic surfaces to restore or create a gap. More particular the present invention is directed to an implant device made from polymeric material and having a stiffness gradient as well as a limited dimensional deformation, wherein the implant device has a stiffness gradient and a limited dimensional deformation and preferably is at least partially anisotropic.
