The implant consists of a layer (2) of a biocompatible material made from monofilaments or multifilaments knitted with a reinforcing material that prevents unravelling and provides macro-porosity, with a hollow cylindrical protuberance (3) on one side. The implant consists of a layer (2) of a biocompatible material made from monofilaments or multifilaments knitted with a reinforcing material that prevents unravelling and provides macro-porosity, with a hollow cylindrical protuberance (3) on one side. The basic layer is flat and large enough to cover the posterior wall of the inguinal canal. The protuberance is in the middle of its width and a third of the way along its length; its open end (3a) lies in the plane of the layer (2), and its base (3b) is flat, forming a cylindrical chamber with a diameter of about 20 mm and a depth no greater than the diameter.
