The implantable plate for wall reconstruction comprises a textile support having anti-migratory protuberances on at least one face.If the support comprises thermoplastic fibers or filaments, each protuberance is formed with a conical configuration, by swaging, inside a peripheral zone in which said fibers or filaments are thermowelded, especially by ultrasound, a perforation being centered relative to the peripheral zone.The two faces can comprise protuberances, of a height substantially equal to the thickness of said support, for example distributed in a stagger and alternating from one face to the other, at the rate of 0.5 to 2 per cm2.The plate can comprise radio-opaque marking in the form of lines passing between the protuberances to constitute a grid.
