Intended Use
The STERIZONE® VP4 Sterilizer is intended for use in terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities. The single pre-set cycle of the STERIZONE® VP4 Sterilizer uses hydrogen peroxide and ozone. The injection of vaporized hydrogen peroxide is followed by the injection of ozone, which reacts with residual hydrogen peroxide to form hydroxyl radicals. Sterilization efficacy was demonstrated using a representative sample of one or more device types and packaging, in seven separate validation loads, as described in Table 1. The load to be processed should be maintained between 20℃ to 26℃ (68°F to 78°F). Total load weight shall not exceed 75 lbs, inclusive of the containers/packaging weight but excluding the 25 Ibs loading rack.
Device Description
The STERIZONE® VP4 Sterilizer (VP4) is a self-contained stand-alone device, using vaporized hydrogen peroxide and ozone in a multiphase process. The VP4 offers a single sterilization cycle intended for general instruments, single-channel flexible endoscopes, and rigid-channel devices including single-channel and double-channel rigid endoscopes. The VP4 has been modified in order to make it compliant with the European Directive on the Restriction Of use of certain Hazardous Substances also known as « RoHS ». In addition, device software has been modified to include a maintenance mode, among other small changes. Finally, a new sensor has been adopted for monitor and control of chamber pressure.

The document describes a sterilization device and its modifications, focusing on chemical processes, physical parameters (temperature, weight), and software changes for maintenance and compliance. There is no mention of AI or ML in the intended use, device description, or performance studies.

No.
This device is a sterilizer intended for use in the terminal sterilization of reusable medical devices, not for diagnosing, treating, or preventing disease in a patient.

No

The device is a sterilizer intended for terminal sterilization of medical devices, not for diagnosing medical conditions.

No

The device is a physical sterilizer that uses hydrogen peroxide and ozone. While it contains software, it is not a software-only medical device.

Based on the provided text, the STERIZONE® VP4 Sterilizer is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is "terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities." This describes a process for making medical devices sterile for patient use, not a test performed on biological samples to diagnose a condition.
  • Device Description: The description details a sterilizer using hydrogen peroxide and ozone, a process for disinfecting and sterilizing equipment. It doesn't mention any components or functions related to analyzing biological samples.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Providing diagnostic information
    • Using reagents or assays for testing

Therefore, the STERIZONE® VP4 Sterilizer is a medical device used for sterilization, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The modified STERIZONE® VP4 Sterilizer has been designed, constructed and tested to meet the safety and performance requirements of various North American safety codes and standards. The modified STERIZONE® VP4 Sterilizer complies with the applicable portions of the following standards:

  • Canadian Standard Association (CSA) Standard C22.2 No 61010-1: 2004 .
  • . Underwriters Laboratory Standard UL 61010-1: 2004
  • . Federal Communication Commission (FCC) Part 18 / EN 55011
  • International Electrotechnical Commission (IEC) Standard IEC 61326-1: 2012
  • . International Electrotechnical Commission (IEC) Standard 61010-1 :2010, 61010-2-040: 2005

A Fault Tree Analysis and Mitigation (FTA-MIT) and a Failure Mode Effects and Criticality Analysis (FMECA) has been conducted on the entire system of the STERIZONE® VP4 Sterilizer to ensure safety features and control redundancies have been implemented in the design and will be maintained during the manufacturing, installation, maintenance and servicing of the sterilizers.

All RoHS-compliant components have undergone verification testing using the exact same test methods and acceptance criteria as used in the predicate device. The use of a new pressure transducer to monitor and control chamber pressure was verified using the same test methods and acceptance criteria as used in the predicate device.

The software controls of the modified STERIZONE® VP4 Sterilizer have undergone verification and validation testing in accordance with FDA's Guidance entitled "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this sterilizer was considered "moderate risk". Testing was completed with no unresolved anomalies.

The modified STERIZONE® VP4 Sterilizer underwent performance validation testing using the « overkill » approach to demonstrate the effectiveness of the process. Testing on directly inoculated medical devices was conducted employing half-cycle to demonstrate achievement of a sterility assurance level (SAL) of 10-6.

This process has been demonstrated to be effective for terminal sterilization of packaged reusable medical devices.

The predicate device has been modified by manufacturing all device components from RoHS compliant materials, upgrade of the software to include a maintenance mode among other functions, and use of a single pressure transducer to monitor and control chamber pressure. Verification testing has been completed on all modified components using the exact same methods and acceptance criteria as completed on the predicate device. Software verification and validation testing confirms that the modified device will perform as intended under the specified use conditions. Electrical safety, EMC and microbiology testing has been completed on the modified device confirming that it is both as safe and as effective as the predicate device.

Conclusion

The performance testing demonstrates that the STERIZONE® VP4 Sterilizer is substantially equivalent to the identified predicate devices.
