Abstract: The invention relates to a knit having barbs protruding outwards from both faces obtained by knitting yarns of biocompatible material in guide-bars B2, B3 and B4 of a knitting machine, wherein the knitting patterns followed by guide-bars B2 and B3 involve at least two needles and produce an arrangement of yarns defining two faces of the knit, the knitting pattern followed by guide-bar B4 making stitches generating loops protruding outwards from each of the faces of the knit, guide-bar B4 being threaded with a hot-melt monofilament yarn, heat-setting the knit, forming barbs by cutting the loops via melting.

Abstract: In-vivo systems and methods for the detection of early signs of post-surgery infection are described. The in-vivo systems include a drain system with a tube configured to drain fluids from a surgery site, at least one sensor unit for sensing the presence of at least one infection biomarker, a processor for processing a signal generated by the at least one sensor unit, a transmitter for transmitting the signal, and a notification system for receiving the signal, analyzing the signal by comparing it to a threshold, determining presence of infection, and generating an indication on the presence of infection.

Abstract: The present invention relates to a prosthetic fabric (5) comprising an arrangement (2) of yarns that define at least first and second opposite faces (2a, 2b) for said fabric, said fabric comprising on at least said first face, one or more barbs (3) that protrude outwards relative to said first face, said fabric being covered, at least partly, on said second face with a microporous layer made of a bioresorbable material, said barbs being covered with a coating made of a water-soluble material. The invention also relates to a process for obtaining such a fabric and to prostheses obtained from such a fabric.

Abstract: An implant and a process for preparing such an implant are disclosed. The implant includes a porous layer including collagen, a non-porous layer including a collagenic constituent, and a reinforcement component. The non-porous layer is joined to the porous layer and the reinforcement member is embedded into the non-porous layer. The porous layer has a three dimensional density ranging from about 20 mg collagen/cm3 to about 200 mg collagen/cm3.
