Patent number: 8658092Abstract: A chemical vapor sterilization process is enhanced by concentrating a germicide via exploitation of the difference between the vapor pressures of the germicide and its solvent. A diffusion restriction can be placed into the diffusion path to assist this process and the path then opened to provide rapid diffusion of the thus concentrated germicide. The path through the diffusion restriction can be closed to allow the pressure in a sterilization chamber to be lowered prior to receiving the concentrated germicide.Type: GrantFiled: February 15, 2013Date of Patent: February 25, 2014Assignee: Ethicon, Inc.Inventors: James P. Kohler, Szu-Min Lin, Richard Jed Kendall

Patent number: 7807100Abstract: A chemical vapor sterilization process is enhanced by concentrating a germicide via condensation and re-vaporization thereof, exploiting the difference between the vapor pressures of the germicide and its solvent to extract some of the solvent during the condensation process.Type: GrantFiled: March 31, 2003Date of Patent: October 5, 2010Assignee: Ethicon, Inc.Inventors: Alfredo Choperena, Harold R. Williams, Szu-Min Lin, Robert Lukasik, Richard Jed Kendall, James P. Kohler

Patent number: 7713473Abstract: A sterilizer employs a vaporizer having sloped surfaces over which flow liquid sterilant solution for vaporization. The arrangement promotes even distribution of the sterilant solution for more efficient vaporization.Type: GrantFiled: June 30, 2005Date of Patent: May 11, 2010Assignee: Ethicon, Inc.Inventors: Richard Jed Kendall, James P. Kohler, Szu-Min Lin

Patent number: 7670550Abstract: A method of sterilizing an article includes placing the article into a chamber containing an inner atmosphere and exhausting the inner atmosphere to lower pressure in the chamber. Hydrogen peroxide vapor is present in the chamber during at least a portion of the step of exhausting the inner atmosphere. Exhaustion of the inner atmosphere is terminated and additional hydrogen peroxide is admitted into the chamber. Hydrogen peroxide vapor contacts the article for a sufficient period to effect sterilization of the article.Type: GrantFiled: March 30, 2005Date of Patent: March 2, 2010Assignee: Ethicon, Inc.Inventors: Szu-Min Lin, Paul T. Jacobs, Jenn-Hann Wang, James P. Kohler, Richard Jed Kendall, Harold R. Williams, Robert Lukasik

Patent number: 7267806Abstract: A chemical vapor sterilization process is enhanced by concentrating a germicide via condensation and re-vaporization thereof, exploiting the difference between the vapor pressures of the germicide and its solvent to extract some of the solvent during the condensation process. A heat pump coupled with the condensation surface enhances the speed and efficiency of condensing and revaporizing the germicide.Type: GrantFiled: March 31, 2003Date of Patent: September 11, 2007Assignee: Ethicon, Inc.Inventors: Richard Jed Kendall, James P. Kohler, Harold R. Williams, Szu-Min Lin, Robert Lukasik

Patent number: 5939033Abstract: A system to deliver gas/vapor from solid materials. Specifically, the delivery system for the use of gas or vapor released from a solid material, such as a non-aqueous/solid hydrogen peroxide complex. The system is comprised of a delivery system that is configured to receive a plurality of disks containing the solid material and provide these disks into an injector. The injector heats the disks to produce a gas or vapor that is then provided into a chamber. The sterilization process can be done by gas or vapor alone, or in combination with plasma or ultra violet radiation. In particular, a control system automatically induces the delivery system to provide the injector with a disk and then remove the disk once the injection sequence is complete.Type: GrantFiled: October 28, 1996Date of Patent: August 17, 1999Assignee: Johnson & Johnson Medical, Inc.Inventors: Richard Jed Kendall, Xiaolan Chen, Michael Hahs, Paul Taylor Jacobs, Szu-Min Lin, Robert M. Spencer, Harold R. Williams
