摘要： 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.

摘要： Medical implants such as bone graft substitutes that include one or more cations are delivered in a local environment to promote osteogenesis. Zeolite loaded with a metal cation in combination with an implant such as a bone graft substitute can be used as an implant in the body to regulate protein transcription and translation. Also disclosed are methods of promoting osteogenesis in a patient in need thereof, methods for modulating bone formation and mineralization by implanting in a patient a medical implant comprising ion-exchangeable cations, and methods of regulating BMP gene expression in bone cells in a patient by controlling the delivery of certain cations through ion-exchange via a zeolite incorporated in a bone substitute implanted in a patient so that BMP gene expression can be upregulated or downregulated appropriately.

摘要： Methods of post-loading ceramic particles with antimicrobial metal cations are disclosed. In certain embodiments, the post-loaded particles are zeolites, wherein the zeolites have been incorporated into a resin and the combination is used as an implantable device. In certain embodiments, the polymer is a thermoplastic polymer such as polyaryletheretherketone (PEEK). In certain embodiments, the source of antimicrobial activity includes ion-exchangeable cations contained in a zeolite. In certain embodiments, disclosed are methods of imparting antimicrobial activity to devices by controlling the delivery of certain cations through ion-exchange via a zeolite incorporated in the device.
