US Patent:

6627150, Sep 30, 2003

Filed:

Dec 29, 1999

Appl. No.:

09/474285

Inventors:

Paul Jacobs - Canyon CA
Szu-Min Lin - Laguna Hills CA

Assignee:

Ethicon, Inc. - Skillman NJ

International Classification:

A61L 220

US Classification:

422 33, 422 23, 422 27, 422 28

Abstract:

The present invention relates to a process for sterilization of medical instruments by concentrating a sterilant such as hydrogen peroxide inside of a sterilizer and sterilizing articles therewith. This concentrating process is monitored by determining the concentrations of water and peroxide in the chamber.

Appl. No.:

09/474142

Inventors:

Paul Jacobs - Canyon CA
Szu-Min Lin - Laguna Hills CA

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61L 220

US Classification:

422 27, 422 33

Abstract:

The present invention relates to a process for sterilization of medical instruments by concentrating a sterilant such as hydrogen peroxide inside of a sterilization chamber and sterilizing articles therewith. The sterilant is concentrated by removing more water from the sterilization chamber than peroxide.

Filed:

Oct 11, 2001

Appl. No.:

09/975714

Inventors:

Paul Jacobs - Canyon CA, US

International Classification:

A61L002/20

US Classification:

422/033000, 422/023000

Abstract:

A method for sterilizing a device, includes the following steps: contacting the device with liquid sterilant outside or inside a sterilization chamber at a first pressure, placing the device in the chamber before or after the contacting step, and decreasing the pressure of the chamber to a second pressure below the vapor pressure of the liquid sterilant. At least the decrease in pressure below about the vapor pressure of the liquid sterilant occurs at a pumpdown rate of less than 0.8 liters per second, calculated based on the time required to evacuate the chamber from atmospheric pressure to 20 torr when the chamber is empty and dry.

Appl. No.:

8/549425

Inventors:

Paul Taylor Jacobs - Canyon CA
Szu-Min Lin - Laguna Hills CA
Xiaolan Chen - Irvine CA

Assignee:

Advanced Sterilization Products - Irvine CA

International Classification:

A61L 900

US Classification:

422 29

Abstract:

An apparatus and process for hydrogen peroxide vapor sterilization of medical instruments and similar devices make use of hydrogen peroxide vapor released from an inorganic hydrogen peroxide complex. The peroxide vapor can be released at room temperature and atmospheric pressure; however, the pressure used can be less than 50 torr and the temperature greater than 86. degree. C. to facilitate the release of hydrogen peroxide vapor. The heating rate can be greater than 5. degree. C. Optionally, a plasma can be used in conjunction with the vapor.
