Patent number: 6977061Abstract: A method and an apparatus for sterilizing a lumen device. A lumen and a container having an interface on a wall of the container are enclosed in a chamber. The lumen is placed across the interface so that one end of the lumen is in the container and the other end is in the chamber. Germicide is introduced into the chamber, and a pressure difference is created between the two ends of the lumen, so that the germicide flows through the lumen. The lumen may alternatively be placed across an interface which separates the chamber into two areas. Germicide is introduced into the chamber, and a pressure difference is created between the two areas of the chamber, causing the germicide to flow through the lumen.Type: GrantFiled: March 8, 2001Date of Patent: December 20, 2005Assignee: Ethicon Endo-Surgery, Inc.Inventors: Szu-Min Lin, Paul Taylor Jacobs
