A non-metallic antimicrobial impregnated medical implant, such as a catheter, and a method for impregnating a non-metallic medical implant with an antimicrobial agent is provided. The method for making the impregnated implant comprises the steps of forming an antimicrobial composition of an effective concentration to inhibit the growth of organisms, such as staphylococci, other gram-positive bacteria, gram-negative bacilli and Candida and applying the antimicrobial composition to at least a portion of the medical implant under conditions where the antimicrobial composition permeates the material of the medical implant. The antimicrobial composition is formed by dissolving an antimicrobial agent in an organic solvent, adding a penetrating agent to the composition, and adding an alkalinizing agent to the composition. The antimicrobial composition is preferably heated to a temperature between about 30 °C and 70 °C prior to applying the composition to the medical implant to enhance the adherence of the antimicrobial agent to the medical implant material. After the impregnated implant is removed from the antimicrobial solution, the impregnated implant is allowed to dry, then rinsed with a liquid and milked to remove excess granular deposits and ensure uniform color of the impregnated implant.

Cette invention concerne un implant médical non métallique imprégné d'un agent antimicrobien, tel qu'un cathéter, ainsi qu'un procédé permettant d'imprégner un implant médical non métallique d'un agent antimicrobien. Le procédé de fabrication de cet implant imprégné consiste à élaborer tout d'abord une composition antimicrobienne ayant une concentration efficace suffisante pour empêcher la croissance d'organismes, tels que staphylocoques, autres bactéries Gram positif, bacilles Gram négatif et Candida, puis à appliquer la composition antimicrobienne à au moins une partie de l'implant médical dans des conditions permettant à cette composition antimicrobienne de pénétrer dans la matière de l'implant médical. On obtient la composition antimicrobienne en dissolvant un agent antimicrobien dans un solvant organique et en ajoutant à cette composition un agent pénétrant puis un agent d'alcalinisation. De préférence, on chauffe cette composition antimicrobienne à une température comprise entre environ 30 ·C et 70 ·C avant de l'appliquer à l'implant médical de façon à accroître l'adhésion de l'agent antimicrobien à la matière de l'implant médical. Une fois que l'on a extrait l'implant imprégné de la solution antimicrobienne, on laisse sécher ledit implant imprégné puis on le rince avec un liquide et on le presse pour éliminer les dépôts granuleux excédentaires et assurer à l'implant imprégné une uniformité de couleur.
