Patent number: 9107765Abstract: Devices such as orthopedic implants are composed of a thermoplastic resin such as polyaryletheretherketone (PEEK), and include a ceramic species, such as a zeolite, to enhance its hydrophilic properties. The ceramic species can be a surface coating, can be incorporated or embedded into the thermoplastic resin, or can be both a surface coating and incorporated or embedded into the resin. In certain embodiments, the ceramic species is zeolite that is incorporated into the device, especially at the exposed surface of the device, and is devoid of antimicrobial metal ions. The device is introduced into the body surgically.Type: GrantFiled: May 6, 2011Date of Patent: August 18, 2015Assignee: DiFusion Technologies, Inc.Inventors: Gary Ghiselli, Peter Whang, Jami Hafiz, Joseph Crudden, Derrick W. Johns

Publication number: 20120141599Abstract: 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.Type: ApplicationFiled: March 30, 2010Publication date: June 7, 2012Applicant: DIFUSION TECHNOLOGIES, INC.Inventors: Derrick Johns, Matthew Geck, Peter Whang, Jami Hafiz

Patent number: 8137588Abstract: Described herein are batches of nanoscale phosphor particles having an average particle size of less than about 200 nm and an average internal quantum efficiency of at least 40%. The batches of nanoscale phosphor particles can be substantially free of impurities. Also described herein are methods of manufacturing the nanoscale phosphor particles by passing phosphor particles through a reactive field to thereby dissociate them into elements and then synthesizing nanoscale phosphor particles by nucleating the elements and quenching the resulting particles.Type: GrantFiled: March 11, 2008Date of Patent: March 20, 2012Assignees: Nitto Denko Corporation, Regents of the University of MinnesotaInventors: Jami Hafiz, Toshitaka Nakamura, Steven L Girshick, Joachim V.
