Triclosan and silver compound containing medical devices
First Claim
1. An anti-infective medical article prepared by exposing a polymer-containing medical article, for an effective period of time, to a treatment solution comprising between about 0.1 and 5 percent of a metal compound, between about 0.1 and 20 percent triclosan, and between about 0.5 and 10 percent of a hydrogel, wherein neither the treatment solution nor the medical article contain chlorhexidine or a chlorhexidine salt.

Abstract
The present invention relates to polymeric medical articles comprising combinations of triclosan and silver-containing compounds. It is based, at least in part, on the discovery that these agents act synergistically, thereby permitting the use of relatively low levels of both agents. While it had been previously found that triclosan can be particularly useful when used in conjunction with chlorhexidine, it has been further discovered that medical articles having suitable antimicrobial properties may be prepared, according to the present invention, which contain triclosan without chlorhexidine. Such medical articles offer the advantage of preventing or inhibiting infection while avoiding undesirable adverse reactions to chlorhexidine by individuals that may have sensitivity to chlorhexidine.
