Patent number: 7803315Abstract: A surface which carries a material which is infected with prions is cleaned with an alkaline cleaning solution to remove as much proteinaceous material as possible from the surface. The solution contains an alkaline cleaning agent which attacks prions remaining on the surface and which attacks prions removed from the surface during the cleaning step. After the cleaning step, the surface is exposed to a strong gaseous oxidant, preferably hydrogen peroxide vapor. The hydrogen peroxide or other strong oxidant attacks the prions, particularly the unclumped prion strands, deactivating the prions.Type: GrantFiled: April 3, 2002Date of Patent: September 28, 2010Assignee: American Sterilizer CompanyInventors: Gerald E. McDonnell, Kathleen M. Antloga, Herbert J. Kaiser

Patent number: 7393818Abstract: A method of treating the surfaces of medical instruments which are contaminated with prions includes contacting the surface with a composition containing a source of peroxide ions, such as hydrogen peroxide, at a molar concentration of at least 1.5M peroxide (equivalent to approximately 5% hydrogen peroxide) and preferably, about 2M peroxide (approximately 7% hydrogen peroxide). The composition is optionally in the form of a gel. The composition is retained in contact with the surfaces for about 1-2 hours until all or substantially all prion contamination is removed.Type: GrantFiled: April 3, 2007Date of Patent: July 1, 2008Assignee: Steris Inc.Inventors: Gerald E.

Patent number: 7129080Abstract: A proteinaceous material has been found to show similar activity and treatment response to that of disease causing prions, such as CJD. A prion model which incorporates the proteinaceous material has a variety of applications. The model has an ability to be cultured either in vivo or in vitro, allowing rapid screening of potential drugs for treating animals or humans, or methods of treating food products or items which may come into contact with prions, such as medical or dental devices. Several treatment methods and materials have been developed using the model.Type: GrantFiled: October 4, 2002Date of Patent: October 31, 2006Assignee: Steris Inc.Inventors: Kathleen M. Antloga, Gerald E. McDonnell

Patent number: 7001873Abstract: A surface which carries a material which is infected with prions is cleaned with an alkaline cleaning solution to remove as much proteinaceous material as possible from the surface. The cleaning agent is an alkaline cleaning agent which attacks prions remaining on the surface and which attacks prions removed from the surface during the cleaning step. After the cleaning solution is drained, a solution of surfactants, buffers, and heavy metal free corrosion inhibitors is circulated over the surface at 50°–60° C. The surfactants disperse and unclump the prion-contaminated material. A strong oxidant, preferably peracetic acid, is added to the solution to bring the peracetic acid concentration to 1,000–2,500 ppm. The peracetic acid or other strong oxidant attacks the prions, particularly the unclumped prion strands, deactivating the prions. After rinsing and drying, the surface may be wrapped in a microbe impermeable barrier and subjected to terminal sterilization, such as steam autoclaving.Type: GrantFiled: March 14, 2002Date of Patent: February 21, 2006Assignee: Steris Inc.Inventors: Gerald E. McDonnell, Herbert J. Kaiser, Kathleen M. Antloga, Jennifer A. Scocos
