Surgical suture material with an antimicrobial surface and process for providing an antimicrobial coating on surgical suture material
A surgical suture material with an antimicrobial surface is described, the surface exhibiting a coating containing a) at least one fatty acid, b) octenidine dichloride and/or dequalinium chloride and c) optionally oligomeric lactic acid esters. In addition, a process for coating surgical suture material is described which is characterized 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.
1. Surgical suture material comprising an antimicrobial surface, wherein the surface exhibits a coating comprising the following components:
a) at least one fatty acid,
b) at least one of octenidine dichloride and dequalinium chloride, and
c) optionally oligomeric lactic acid esters.
2. Surgical suture material according to claim 1 , wherein the at least one fatty acid is selected from the group consisting of lauric acid, palmitic acid and stearic acid.
3. Surgical suture material according to claim 1 , wherein the weight ratio of component b) to component a) is 1.0:0.1 to 1.0:5.0.
4. Surgical suture material according to claim 3 , wherein the weight ratio is 1.0:1.0.
