Abstract
Abdominal prostheses are used in humans for abdominal wall strengthening or reconstruction. From the mechanical point of view they are membranes, so their basic mechanical property is tensile stiffness. This property is experimentally identified for a selected implant, OptomeshTM. The obtained results are described herein. Uni-axial simple and cyclic tension tests are a basis for the analysis. Both kinds of tests allowed to distinguish two states of the material, namely: baseline and preconditioned. In the preconditioned state the material reveals approximate two-fold increase of tensile stiffness in comparison to baseline state. In both states the material demonstrate orthotropy. Both features are typical for knitted synthetic abdominal implants, however, the first one is not, while the other is desired from the mechanical point of view of operated hernia.
