Prosthesis () comprising a patch () made of biocompatible material, said patch having a generally plane geometric shape that defines two opposite faces, a centre, a length and a width of said patch, characterized in that said patch is provided, on one () of its faces, with a single marking means () designed to indicate both the centre (C) of the patch and also the longitudinal direction of said patch.

Hernia prosthesis with marking means

The present invention relates to a prosthesis () for hernia repair comprising a reinforcement layer (), a first barrier layer () of anti-adhesion material covering at least a part of a surface of the reinforcement layer, and a second barrier layer of anti-adhesion material covering a remaining part of the surface of the reinforcement layer, the second barrier layer being formed of one or more flap member(s) ().

Prosthesis for hernia repair

The invention relates to a method for forming a barbed suture () comprising: a) producing a knit by knitting together i) a set of chain stitch yarns () producing chain stitches and ii) a set of monofilament weft yarns completing weft stitches with at least one of said chain stitches, thereby producing at least one weft stitched chain stitch (), b) cutting the knit along the warp direction on both sides of said weft stitched chain stitch, so as to isolate said weft stitched chain stitch from the rest of the produced knit, the chain stitch yarn of said at least one weft stitched chain stitch forming the elongate body () of the barbed suture and the monofilament cuts () extending from said weft stitches of said one weft stitched chain stitch forming the barbs () of said barbed suture.

Method for preparing a chitosan-based porous layer The present invention relates to a method or preparing a chitosan-based, neutralized compressed porous layer, comprising the following steps: &#x2014;a) a chitosan solution is prepared, &#x2014;b) said solution is poured into a mold in order to form a layer, &#x2014;c) the layer obtained in b) is lyophilized so as to obtain a porous layer, &#x2014;d) said porous layer obtained in c) is compressed, &#x2014;e) the compressed porous layer obtained in d) is neutralized by means of an NHOH solution. It also relates to an implant comprising a layer obtained according to such a method.

A method for manufacturing an implantable film and a prosthesis comprising such a film The present invention relates to a method for manufacturing a non porous film intended to be implanted in the human body, said method comprising the following steps: preparation of a first film, called intermediate film, via gelling of a starting solution comprising at least one polymer selected in the group consisting of collagen, glycosaminoglycans, and mixtures thereof, immersion of said intermediate film in an alkaline composition comprising at least one C-Calcohol, drying of the film obtained at the end of the immersing step. The invention also relates to a method for manufacturing a prosthesis comprising a textile support and such a film.
