Abstract: A mesh (1) made of monofilament polypropylene (PPL) with surgical quality (CQ) and controlled flat memory (CM), having upper (1?) and lower (1?) layers joined by welding along almost the entire length of their edges (p). The layers have equal coaxial holes (2?, 2?) for passage of the spermatic cord of a patient, two radial slits (3?, 3?) departing from said holes and forming an angle between 9° and 120°, the zone (q) of the edges between the slits being free so as to create an upper (5?) and a lower (5?) fins that can be easily bent.
