Patent number: 9717812Abstract: A biological sterilization indicator, system, and methods of determining the effectiveness of a sterilization process. The biological sterilization indicator can include a locus of spores, a reservoir containing a liquid, and a sterilant path positioned to provide fluid communication between ambience and the locus of spores. The reservoir can have a closed state in which the reservoir is not in fluid communication with the locus of spores and an open state in which the reservoir is in fluid communication with the locus of spores. The biological sterilization indicator system can include the biological sterilization indicator and a detection device adapted to be coupled to the biological sterilization indicator. In some embodiments, the method can include assaying the spores for a detectable change in a characteristic, and detecting substantially all of the detectable change.Type: GrantFiled: February 18, 2015Date of Patent: August 1, 2017Assignee: 3M INNOVATIVE PROPERTIES CO.Inventors: Sailaja Chandrapati, Jeffrey C. Pederson, Heather M. Webb, Jeffrey D. Smith, Kurt J. Halverson, Bryan S. Behun, Peter D. Ludowise

Patent number: 9428786Abstract: A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The BI can further include a frangible container containing a liquid and dimensioned to be positioned in the housing. The reading apparatus can be configured to detect activation of the biological sterilization indicator, for example, by detecting that the second portion is in the second position, and/or by detecting that the liquid from the frangible container is present in a specific chamber of the biological sterilization indicator. The method can include positioning the BI in the well of the reading apparatus and detecting activation, for example, by detecting one or more of the above conditions.Type: GrantFiled: August 18, 2015Date of Patent: August 30, 2016Inventors: Jeffrey C. Pederson, Sailaja Chandrapati, Bryan S. Behun, Barry W. Robole, Leroy J. Longworth

Publication number: 20040197848Abstract: A high capacity reader detects fluorescence emitted by a biological indicator to determine the efficacy of a sterilization cycle. The reader permits a large number of biological indicators to be read in rapid succession. For example, the biological indicators may be pre-incubated in a separate, high capacity incubator and then placed in a high capacity reader for fluorescence detection. The reader makes a positive or negative growth determination based on a single fluorescence threshold comparison for each pre-incubated biological indicator. The single fluorescence threshold comparison involves comparison of measured fluorescence to a baseline fluorescence of a reference biological indicator. The reader acquires the baseline fluorescence from the reference biological indicator, and thereafter uses the baseline fluorescence as the threshold for subsequent biological indicators processed by the reader.Type: ApplicationFiled: April 1, 2003Publication date: October 7, 2004Inventors: Bryan S.
