A surgical suture material with an antimicrobial surface is described, the surface exhibiting a coating containing at least one fatty acid, octenidine dichloride and/or dequalinium chloride and optionally oligomeric lactic acid esters. In addition , a process for coating surgical suture material is described which is characterised by the fact that the thread material is wetted with a homogeneous methanolic solution of octenidine dichloride and/or dequalinium chloride and subsequently the methanol is evaporated, a coating forming on the thread surface.
L'invention porte sur une matière destinée aux sutures chirurgicales, laquelle présente une surface antimicrobienne. La surface est induite d'un revêtement constitué d'au moins un acide gras, le dichlorure d'octénidine et/ou le chlorure de dequalinium et, facultativement, des esters de l'acide lactique oligomères. En outre, un procédé permettant d'induire le revêtement sur la matière destinée aux sutures chirurgicales est décrit. On mouille la matière (fil) avec une solution méthanolique homogène de dichlorure d'octénidine et/ou de chlorure de dequalinium et, ensuite, on évapore le méthanol, ce qui crée un revêtement à la surface du fil.
