Abstract
The present invention generally relates to the field of prostheses for surgical applications, to methods of their manufacturing and to methods of treating a patient by implanting them into a patient. More particularly, the present invention relates to prostheses having a multi-layered sheet structure and their use in hernia repair, the repair of anatomical defects of the abdominal wall, diaphragm, and chest wall, correction of defects in the genitourinary system, and repair of traumatically damaged organs such as the spleen, liver or kidney.
Claims28
A method of manufacturing a prosthesis having a multi-layered sheet structure, comprising integrally forming at least two continuous polymer film layers with no distinguished filaments or fibers within each layer, wherein the at least two continuous polymer film layers are in continuous contact with each other to produce the multi-layered sheet structure, and wherein the outermost layer of the multi-layered sheet structure is formed by casting the polymer on a roughened mold to obtain a roughed surface, forming the additional layers thereon and, then, mechanically or chemically treating said roughed surface to increase its surface friction and wetting ability.
