Abstract: A hernia prosthesis includes a first portion defining a bag joined to a second portion constituting a one-piece body. A top plate of the first portion has a plurality of radial tabs around a central opening. The second portion has three distinct successive zones including a first median zone in the form of a very long sheath for introducing and securing an inserter-unfolder device. The median portion is prolonged downwards by a plurality of bands uniformly radially disposed and having bottom ends divided into two each respectively to form two tongues in a Y fastening configuration. Each tongue is fastened by its terminal end to one of the tabs. The second portion, in a top zone, beyond the sheath, comprises two very high tongues which have, in their top portion, a longitudinal slit in their width for attaching the inserter-unfolder device.
