MEDICAL DEVICE WITH ANTIMICROBIAL LAYER

摘要

A medical device includes a conduit for a fluid. The conduit has a wall formed of a hydrophobic polymer with a hydrophilic polymer layer extruded over it, and an antimicrobial substantially dispersed within the hydrophilic polymer. The antimicrobial compound may be a predetermined amount of phosphorus-based glass having a predetermined quantity of a metal such as silver substantially dispersed therein. The medical device may be an endotracheal tube made by providing a hydrophobic polymer, a hydrophilic polymer and an antimicrobial compound, forming the hydrophobic polymer, the hydrophilic polymer and the antimicrobial compound into a conduit, and forming a cuff on an end of the conduit.
