Barbed prosthetic knit and hernia repair mesh made therefrom as well as process for making said prosthetic knit

摘要

The present invention relates to a prosthetic knit based on at least a first yarn of biocompatible polymer material defining first and second opposite and openwork faces, and on at least a second biocompatible and heat-fusible monofilament yarn, forming barbs that protrude outwards from at least said first face and are obtained by melting loops generated by said second yarn, the chart followed for the knitting of said first and second yarns on a warp knitting machine having three guide bars B1, B2, B3 being the following, according to the ISO 11676 standard:—Bar B1: 1.0/0.1//—Bar B2: 1.0/7.7/6.6/7.7//—Bar B3: 2.1/5.5/3.4/0.0// said second yarn following the chart of bar B3. The present invention also relates to a process for manufacturing such a knit.
