In order to make improved threads provided with barbs for surgical purposes, it is envisaged to use threads of polyhedral or stochastic shape and to provide the barbs on said threads, by making a cut in a point corresponding to an edge of the aforesaid polyhedral or stochastic shapes for each barb, preferably by means of techniques of laser etching that enable also barbs with double tip to be obtained so as to increase the biological and histomorphological interaction with the tissues of the host. |
