Method of manufacturing antimicrobial implants of polyetheretherketone
First Claim
1. A method of making a load bearing antimicrobial implant, comprising drying polyetheretherketone resin to a residual moisture content of less than 0.1% moisture by weight, heating said dried polyetheretherketone resin to a temperature effective to melt said resin, blending into said molten resin a metal zeolite comprising silver zeolite, cooling said blend, and forming said blend into said implant.

Abstract
Methods of fabricating implantable medical devices, preferably with PEEK, having antimicrobial properties, are disclosed. The antimicrobial effect is produced by incorporating ceramic particles containing antimicrobial metal cations into molten PEEK resin, which is subsequently allowed to cool and set in its final shape achieved by injection molding, cutting and machining or other techniques.
