Mechanical testing of light mesh endoprosthesis Ultrapro for stretching and bending resistance showed strong anisotropy of the material along and across the loop columns. Ultrapro endoprosthesis was placed parallel and perpendicularly to the midline during plastic repair of a hernial defect in rats. Six months after surgery, the development of hernias and violation of endoprosthesis structure were observed in the group with longitudinal orientation of the endoprosthesis. Transverse orientation of the endoprosthesis led to fortification of the defect site. However, the meshes were in some cases misshapen and formed folds across the loop columns, because of insufficient bending rigidity and elasticity of the material.
