Patent number: 10350319Abstract: Liquid water detection in a sterilization chamber that can distinguish liquid water from material in the load that is outgassing and can dry the liquid, is independent of the vacuum pump and chamber leak rate, and that is capable of detecting small amounts of liquid and drying the liquid without freezing the liquid in the process is achieved by monitoring conditions in the chamber at two different pressures, one above the boiling point of water and another below the boiling point of water at a given load temperature.Type: GrantFiled: January 23, 2017Date of Patent: July 16, 2019Assignee: Sterilucent, Inc.Inventors: Steven J. Olson, Kent A. Larson, Jennifer M. Berg, Dominique J. Megran

Patent number: 9766012Abstract: The removal of moisture from an object to be sterilized is provided through at least the steps of placing the load in the chamber, reducing the pressure within the chamber to increase the rate of evaporation of moisture from the load, monitoring over a predetermined period of time the increase in the quantity of vapor within the chamber resulting from evaporation of moisture from the load, admitting gas into the chamber and repeating the steps following placing the load into the chamber.Type: GrantFiled: June 19, 2012Date of Patent: September 19, 2017Assignee: Sterilucent, Inc.Inventors: Jami McLaren, Steven J. Olson, Kent Larson

Patent number: 8840836Abstract: An apparatus and method for achieving low temperature vapor sterilization of objects which may involve objects having a lumen. Following evacuation of the sterilization chamber and the introduction of a vaporous or gaseous sterilant, the volume of the chamber is changed by actuation of a movable boundary in the chamber to increase and decrease the pressure in the chamber thus driving the sterilant into and out of such lumens.Type: GrantFiled: March 16, 2012Date of Patent: September 23, 2014Assignee: Sterilucent, Inc.Inventor: Steven J. Olson

Patent number: 8486691Abstract: A device useful in determining the efficacy of a chemical sterilization process includes a dead end cavity closed by an access cap having a port coupled to a challenge tube defining the only path by which a substantial quantity of sterilant can reach the cavity. A biological indicator is located within the cavity and a chemical indicator is also provided. These indicators, and particularly the biological indicator, provide an indication of whether chemical sterilant would reach all interior exposed surfaces of a load in sufficient concentrations to adequately sterilize the load.Type: GrantFiled: April 12, 2010Date of Patent: July 16, 2013Assignee: Sterilucent, Inc.Inventors: Kent Larson, Patrick LaValley, Jami McLaren, Steven J. Olson

Patent number: 7993609Abstract: A container is provided for holding a chemical compound or mixture. Areas are provided on the surface of the container which allow for gaseous by-products from the chemical contained within the container to permeate from a chamber through the surface of the container. A septum is over-molded into the surface of the container. The septum is formed in such a manner that it provides a sealing effect to close an opening in the container.Type: GrantFiled: December 30, 2008Date of Patent: August 9, 2011Assignee: Sterilucent, Inc.Inventor: Patrick LaValley

Publication number: 20100053621Abstract: Accurate measurements of the concentration of a sterilant in a sterilization chamber are provided through the use of a light source, a first detector that receives light from the light source that has not passed through the sterilization chamber and a detector that receives light from the light source that has passed through the sterilization chamber. The light contains wavelengths known to be absorbed by the sterilant. A controller receives and processes signals received from the two detectors to cancel changes in the output of the light source and then apply a modified Beer-Lambert law to determine the concentration of the sterilant gas.Type: ApplicationFiled: August 29, 2008Publication date: March 4, 2010Applicant: Phygen, Inc. d/b/a Sterilucent, Inc.Inventors: Steven J.
