Patent number: 9439991Abstract: A method for decontaminating a medical device includes enclosing the medical device in an enclosure including a fog-permeable layer and an exterior port member coupled to the fog-permeable layer. The exterior port member of the enclosure is coupled to a chemical dispersing interface in a decontamination chamber. A pressure in the decontamination chamber is reduced to a sub-atmospheric pressure in a first evacuation step. A room temperature decontaminating fluid is introduced as a fog into the decontamination chamber. The fog is held in the decontamination chamber for a decontaminating time. The pressure in the decontamination chamber is reduced to a sub-atmospheric pressure in a second evacuation step. The decontamination chamber is vented to atmospheric pressure.Type: GrantFiled: August 29, 2014Date of Patent: September 13, 2016Assignee: MEDIVATORS INC.Inventors: Mason Schwartz, Jonathan K. Olson, Thomas M. Gentle, Jr., John E. Marxer, Michael P. Petersen

Patent number: 8821807Abstract: A pouch for retaining an endoscope during and after a decontamination process includes a first pouch side, a second pouch side attached to the first pouch side to form the pouch that is configured to retain the endoscope, and a port member coupled to the second pouch side. The second pouch side is securable to the first pouch side to seal the endoscope within the pouch. The second pouch side is configured to permit passage of a decontaminating substance. The port member is coupled to the second pouch side and includes an external interface configured to be connected to a device that provides the decontaminating substance for passage through the port member into an interior of the pouch.Type: GrantFiled: December 3, 2010Date of Patent: September 2, 2014Assignee: Medivators Inc.Inventors: Mason Schwartz, Jonathan K. Olson, Thomas M. Gentle, Jr., John E. Marxer, Michael P. Petersen

Patent number: 7901349Abstract: Apparatus and method for detecting connectivity in a channel in an endoscope undergoing reprocessing using an automatic reprocessor, the apparatus including a source of pressurized fluid which may be a gas alone or gas and liquid and a back pressure detector connected to the channel or channels of interest in the endoscope, the method including providing a source of pressurized fluid, directing the pressurized fluid to a channel in an endoscope, monitoring the time for the back pressure in the pressurized fluid to decay to a predetermined level; and determining whether the channel is connected and open or disconnected by comparing the decay time of the actual back pressure to one or more predetermined values corresponding to the specific channel or channels and model of endoscope undergoing reprocessing.Type: GrantFiled: November 2, 2005Date of Patent: March 8, 2011Assignee: Minntech CorporationInventors: Paul T. Feld, Michael P. Petersen, John E. Marxer, Ward J. Sly, Johannes Antonius Walta

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. Marxer, Ward J. Sly, Patricia M. Stanley, Gregory Worsnick, Kurt J. Weimer, Bruce D. Martin, Mary Beth B. Henderson, Bradley K. Onstad

Patent number: 4553137Abstract: An improved ice detector has a vibrating element which has a front portion and vibrating means suitably disposed with respect to the vibrating element for exciting the vibrating element into vibration and means for sensing a shift of the frequency of vibration of the vibrating element resulting from a change of mass of the vibrating element due to ice accumulating thereon. The improvement is characterized in that the ice detector is supported with respect to a surface exposed to an air stream such that a cap on which ice forms and which is disposed on the front portion of the vibrating element, is exposed to the air stream and is formed to be substantially conformal to such surface.Type: GrantFiled: June 1, 1983Date of Patent: November 12, 1985Assignee: Rosemount Inc.Inventors: John E. Marxer, John W. Kowles
