  • Publication number: 20200338238
    Abstract: 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.

  • Publication number: 20200315802
    Abstract: Anti-biofilm osseointegrating implantable devices are made by additive manufacturing. A powder formulation is made that includes a resin such as a polyarylether ketone such as PEEK, and a zeolite, and the zeolite may be loaded with one or more therapeutic metal ions, such as silver, copper and/or zinc that exhibit antimicrobial properties. The powder formulation also may include a porogen to control the porosity of the resulting three-dimensional implant device. The devices, which are osseointegrating, may include metal-loaded zeolite so as to elute antimicrobial metal ions in a therapeutically effective amount when implanted into a body and exposed to bodily fluid.

  • Patent number: 8999310
    Abstract: Keratinous fiber treatment formulations and methods of providing a long lasting set in keratinous fibers such as hair by applying a polymer system to the hair which provides a stable set to the hair which will last at least until the hair is thoroughly washed. The set is made more permanent by incorporating a reducing agent such as L-cysteine into the polymer system and allowing the system to air oxidize over time or optionally applying a second chemical oxidizing system to the treated hair which will accelerate the oxidation process and the setting rate of the hair.
