Alternatives to STERIS System 1

FDA-cleared sterilization and disinfection products

The purpose of this document is to help health care facilities and health care professionals identify legally-marketed alternatives to replace the STERIS System 1 (SS1).

Recommendations for identifying replacement reprocessing devices

As healthcare facilities and professionals review the available options, FDA recommends the following steps:

  • Identify which devices your facility is currently reprocessing using an SS1
  • For each device being reprocessed, identify the type of reprocessing needed by
    • Reviewing the manufacturer's instructions for reprocessing for each device
    • Reviewing relevant guidance from the CDC and various professional organizations on device reprocessing (see links at the end of this document)
    • Considering the Spaulding classification for reprocessing (after thorough cleaning)
      • Critical device - used in a normally sterile body site - needs sterilization
      • Semicritical device - contacts intact mucosal surfaces - needs high level disinfection
      • Noncritical - contacts only intact skin - needs intermediate or low level disinfection
  • Select a reprocessing device that will provide the type of reprocessing you need for your devices
  • Contact the manufacturer of the reprocessing device to confirm that it will be compatible with your devices and to check its availability
  • If the recommendations from the manufacturers of the medical devices to be reprocessed and the reprocessing device seem to disagree, follow the instructions from the manufacturer of the device to be reprocessed.
Notes about FDA databases

The listings below are derived from public databases of medical devices cleared by FDA. The information in this database is taken from the original files submitted.  In each category, the most recently cleared devices are listed first. Users need to be aware of the following:

  • Some companies have been acquired by other companies or have gone out of business
  • Some products may now be marketed by other companies or under new names
  • Some companies have changed their locations and contact information

FDA will update these listings when new products are cleared or if we learn that a device is no longer on the market.

1.  FDA-cleared Endoscope Washer Disinfectors / Automated Endoscope Reprocessors

This list identifies FDA-cleared Endoscope Washer Disinfectors/Automated Endoscope Reprocessors (AER).  When AERs are listed with specific liquid chemical sterilants or high level disinfectants (LCS/HLD), only those products can be used with the devices. When an AER is listed with "Most FDA Cleared", a number of cleared LCS/HLD can be used with that device. Check with the manufacturer for the specific LCS/HLD that have been validated for use with a particular AER.

2.  FDA-Cleared Liquid Chemical Sterilants/High Level Disinfectants

This list identifies FDA-cleared liquid chemical sterilants and high level disinfectants (LCS/HLD) with general claims for reprocessing reusable medical devices.

While all LCS/HLD are required to demonstrate their ability to kill spores (liquid chemical sterilant), not all of these are practical for device sterilization.  Some of these products require a long contact time for sterilization.  In many cases, this is impractical and may result in damage to the reprocessed equipment. Therefore, these products are used only at shorter contact times to kill mycobacteria and a small number of spores (high level disinfection). These LCS/HLD products are labeled "No indication for device sterilization".

Please note that some LCS/HLD are labeled "Indication for sterilization". The contact times needed for sterilization with these products are still relatively long (several hours). Most of these products are not practical for sterilization of delicate, heat-sensitive devices such as endoscopes because of the long contact time.

3. FDA-Cleared Low Temperature Sterilizers Using Hydrogen Peroxide or Ozone

This list identifies FDA-cleared low-temperature sterilizers which use hydrogen peroxide vapor/plasma or ozone as the sterilant. These products can terminally sterilize wrapped devices and also devices with lumens. 

The low temperature sterilizer "lumen claims" identify the smallest diameter and the longest channel length dimensions of the endoscopes that they can reprocess. The lumen claims vary by sterilizer model and manufacturer. When evaluating these sterilizers, check their specific claims against the lumen dimensions of any endoscope which you wish to reprocess.

4. FDA-Cleared Ethylene Oxide Sterilizers

This link will take you to a list of FDA-cleared ethylene oxide sterilizers. Most of these devices were cleared some time ago. Their instructions for use will have limited if any information on the endoscope lumen sizes appropriate for use in these sterilizers and they will usually also lack aeration time information specific to endoscopes.

FDA recommends that you review the reprocessing instructions from the endoscope/medical device manufacturer for information on specific ethylene oxide sterilizer cycle time, humidity and concentration (% of ethylene oxide), and aeration time. If this information is not provided in the endoscope/medical device labeling, you should contact the manufacturer of the device to determine the exact reprocessing parameters that have been validated before you reprocess that device in an ethylene oxide sterilizer. 

List of FDA-Cleared Ethylene Oxide Sterilizers

5. List of FDA-Cleared Steam Sterilizers

This link will take you to a list of FDA-cleared steam sterilizers.

Most endoscopes and other reprocessed devices are sensitive to heat and cannot be processed using steam sterilizers. Liquid chemical sterilization is not a terminal sterilization process and should be used only for heat-sensitive devices which cannot be processed by any other method such as low temperature terminal sterilization by hydrogen peroxide, ozone or ethylene oxide.  Any devices that can tolerate steam sterilization, such as certain simple, rigid endoscopes, should be reprocessed using steam sterilization and not in the SS1.

The microbial kill kinetics of liquid chemical sterilization are complex and non-linear. A "sterility assurance level" cannot be calculated for liquid chemical sterilization and this process is to be used only for heat-sensitive devices which cannot be sterilized by any other means.
