This device is a sterilizer designed to sterilize medical instruments. It does not diagnose medical conditions.
No
The device description clearly states it is a traditional ethylene oxide (EO) sterilizer that uses physical components like cartridges and a vacuum vessel, and the performance studies focus on physical and biological efficacy, not software performance.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as sterilizing heat- and/or moisture-sensitive devices, specifically medical instruments and scopes. This is a sterilization process for medical devices, not a diagnostic test performed on biological samples.
- Device Description: The device is described as an ethylene oxide (EO) sterilizer, which is a method for killing microorganisms on surfaces. This aligns with sterilization, not in vitro diagnostics.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring analytes
- Providing information for diagnosis, monitoring, or prognosis of a disease or condition
- Reagents or kits for testing
The device's function is to render medical devices sterile for reuse, which is a critical step in infection control within healthcare settings. This is distinct from the purpose of an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The effectiveness of the sterilization cycles included on the 3M Steri-Vac™ GS5 and 3M Steri-Vac™ GS8 sterilizers is demonstrated by the application of testing and acceptance criteria described in the Recognized Consensus Standard:
· AAMI ST24:1999/(R) 2009 Third Edition; Automatic, general purpose ethylene oxide sterilizers and ethylene oxide sterilant sources intended for use in health care facilities,
Summary of efficacy testing:
- Empty Chamber Test The sterilizer cycles were demonstrated in both models to provide complete inactivation of an AAMI challenge test pack in three consecutive sterilization runs.
- Simulated Load Test The sterilizer cycles were demonstrated in both models to provide complete inactivation of a load of AAMI challenge test packs representing 10% of the chamber volume in three consecutive sterilization runs.
- Sterility Assurance Test The sterilizer cycles were demonstrated in both models to provide complete inactivation of a load of AAMI challenge test packs representing 10% of the chamber volume in three consecutive sterilization runs which were run at half of normal gas exposure time. This test assures >10° sterility assurance level using the ISO 11135-1 "Overkill" approach.
The basis for effective inactivation of microbial spores is control over the critical physical parameters of exposure time, temperature, gas concentration and relative humidity. The performance of the sub-systems controlling these parameters meets the acceptance criteria when tested according to the prescribed methods in AAMI ST 24.
Summary of physical testing:
- Chamber air temperature All models were demonstrated to control the air temperature to set value +/- 3 degrees Celsius according to ST 24 Clause 5.1.5.1 Exposure time – All models were demonstrated to control exposure times to set value +/- 2% according to ST 24 Clause 5.1.5.2
- Gas concentration All models use a single-dose cartridge of 100% ethylene oxide where the entire contents are consumed in each cycle.
- Relative humidity All models were demonstrated to control relative humidity prior to gas exposure at a level ≥ 30% according to ST 24 Clause 5.1.5.3.

Safety
The 3M Steri-Vac™ GS5 and 3M Steri-Vac™ GS8 sterilizers were tested for safety by Underwriters Laboratory to verify compliance to:
- · IEC 61010-1 (2001) Second Edition: Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 1: General requirements,
- IEC 61010-2-010 (2003) Second Edition; Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-010: Particular requirements for laboratory equipment for the heating of materials,
· IEC 61010-2-040 (2005) First Edition: Safety requirements for electrical equipment for measurement, control and laboratory use – Part 2-040: Particular requirements for sterilizers and washer-disinfectors used to treat medical materials
In addition. 3M Steri-Vac™ GS5 and 3M Steri-Vac™ GS8 sterilizers have been tested by a certified testing laboratory to verify electromagnetic compatibility per:
- USA Title 47, Code of Federal Regulations (2009) for:
- Radiated Emissions (FCC Part 15, Subpart B, Class A), and
- Conducted Emissions (FCC Part 15, Subpart B, Class A)
- IEC 61326: Electrical Equipment for Measurement, Control and Laboratory Use-EMC Requirements.
Failure Hazards
Failure of the sterilizer can lead to delayed access to medical instruments, the potential for spread of infection, and the exposure of operators to ethylene oxide. When an error occurs, the system controller aborts the cycle, performs automated error recovery, and displays the error code(s).
7
To avoid hazardous situations, it is essential for users to follow all instructions provided by 3M and the manufacturers of the medical instruments which are being sterilized. The sterilizer must be installed and maintained according to the instructions provided. Operators of the sterilizer must be trained. Only supplies cleared for use in EO sterilization should be used in conjunction with the sterilizer. All applicable national and international standards and recommendations for ethylene oxide sterilization processes should be followed. Improper and incomplete cleaning has been specifically identified by industry and regulatory bodies as a major barrier to ultimately providing sterile medical instruments. Always follow instructions provided by the instrument manufacture for disassembling and cleaning.
User Information
3M provides users with installation manuals, operator manuals and other labeling describing appropriate use of the sterilizers, including information related to safety while working with ethylene oxide. In addition to labeling 3M provides users with in-person and online training, as well as technical assistance over the phone or in-person. Trained and certified service personnel located throughout the world are available for maintenance requests and other field support services.
Conclusion
The 3M Steri-Vac™ GS5 and 3M Steri-Vac™ GS8 sterilizers meet the performance standards of AAMI ST 24 and are substantially equivalent to the predicate device in terms of their intended use, physical properties and technological characteristics. There are no new questions of safety or effectiveness.
