Abstract
An openwork prosthetic knit made in one piece, based on an arrangement formed by several sheets of yarns of a biocompatible polymer material, including a central band and two lateral bands on either side, respectively, of the central band, the elasticity of the knit in the central band being greater than the elasticity of the knit in each of the lateral bands at least two base sheets, a front sheet and a rear sheet, extending at least across the whole surface of the central band, the two base sheets being meshing sheets and defining a first weave, and at least two supplementary sheets, behind the rear base sheet, extending only across the respective surfaces of the lateral bands, the two supplementary sheets being sheets of partial weft and defining a second weave.
