HertraÂ® 9 and HertraÂ® 9A preshaped meshes are used to repair inguinal hernias in laparotomy surgery, and are woven with quadriaxial technology1, a process created and developed by Herniamesh which, when applied to preshaped mesh, produces prostheses that are reinforced along the required direction. Mesh woven with this technology is therefore stronger, smoother and lighter, and maintains its shape under tension. Quadriaxial prostheses can be positioned with or without fixing; in the latter case advantage can be taken of the so-called "Trabucco surgical technique". Furthermore, Hertra 9 prostheses can be handled and adapted as easily as a mesh with higher grammage. The Hertra 9 prostheses is used to treat the male inguinal hernia, while Hertra 9A mesh is used to repair inguinal hernias in females and males in orchifunicolectomy cases.
