Patent number: 7061597Abstract: A system for reprocessing and sterilizing a previously used endoscope having at least one lumen is disclosed. The reprocessing system includes a reaction chamber into which individual chemical components of a sterilant are transferred by pneumatic force. The system includes a central processor which controls the asynchronous reprocessing and sterilization of at least two endoscopes. A novel sterilant is also disclosed. Also disclosed is a combination of the sterilization device and the sterilant and methods of using the same.Type: GrantFiled: July 3, 2002Date of Patent: June 13, 2006Assignee: Minntech CorporationInventors: Raymond Paul Oberleitner, John E.

Patent number: 6797234Abstract: A device and method for cleaning and sterilizing tubular structures particularly, long, narrow tubular structures such as lumens of a medical device such as an endoscope by reversing the flow of fluid in interconnected tubular structures. The device comprises a first and second valve in fluid communication with a first and second tubular structure. The valves selectively switch between a first and second position causing a first and second flow path within the tubular structures, at least a part of the second flow path opposite the first flow path.Type: GrantFiled: May 29, 2001Date of Patent: September 28, 2004Assignee: Minntech CorporationInventor: Patricia M. Stanley

Patent number: 6632397Abstract: The present invention relates to a two-part or multi-part concentrate system for preparing an activated solution which can be diluted with water to a use-dilution solution having improved anti-corrosive properties at room temperature. The concentrate system contains a first component containing at least one oxidizing agent, preferably hydrogen peroxide and a second component containing at least formic acid in a concentration of about 25 wt %. At least one corrosion inhibitor and at least one surfactant are also included in the concentrate system. When mixed and diluted, the resulting solution is excellent in its sterilization and anti-corrosive properties.Type: GrantFiled: September 30, 1999Date of Patent: October 14, 2003Assignee: Minntech CorporationInventors: Mary Beth Henderson, Patricia M. Stanley, Bradley K. Onstad

Patent number: 5718910Abstract: A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.1 to C.sub.4 peroxycarboxylic acid, and a C.sub.6 to C.sub.18 peroxyacid. The combination of these acids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water to a pH in the range of about 2 to 8. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.Type: GrantFiled: January 13, 1993Date of Patent: February 17, 1998Assignee: Ecolab Inc.Inventors: Thomas R. Oakes, Patricia M. Stanley, Jerome D. Keller

Patent number: 5213581Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.Type: GrantFiled: June 15, 1992Date of Patent: May 25, 1993Assignee: Ecolab Inc.Inventors: Lynne A. Olson, Patricia M. Stanley
