Abstract
Applicants' invention is a method for creating an interpenetrating network on the surface of devices and supplies that is biocompatible and antimicrobial. According to Applicants' invention, a polymerizable or monomeric quaternary ammonium salt in a solvent is exposed to a polymeric substrate. The quaternary salt in solvent is absorbed by the polymeric substrate and the quaternary salt is polymerized such that an interpenetrating network is formed with said polymeric substrate.
Claims17
A method of imparting antimicrobial properties to a polymeric substrate comprising:
- providing a polymerizable or monomeric quaternary ammonium salt in a solvent;
- contacting the polymeric substrate to said solvent containing said quaternary salt;
- permitting said quaternary salt to be absorbed by the polymeric substrate;
- and
- polymerizing said quaternary salt such that an interpenetrating polymer network is formed with said polymeric substrate.
A method for creating a catheter having non-leaching, antimicrobial properties comprising:
- providing a polymerizable or monomeric quaternary salt in a solvent;
- providing a catheter;
- and contacting said catheter to said solvent containing said quaternary salt such that said quaternary salt polymerizes within and upon the catheter in situ.
A method for creating a non-leaching, biocompatible, antimicrobial, polymeric coating comprising:
- providing a polymerizable or monomeric quaternary salt in a solvent;
- exposing a substrate having interstices in which said quaternary salt can be absorbed and polymerized;
- permitting said quaternary salt to be absorbed by the substrate;
- and polymerizing said quaternary salt such that an interpenetrating polymer network is formed within the interstices of the substrate.
