Device Story

Biological indicator (BI) for monitoring vapor phased hydrogen peroxide sterilization cycles; consists of Geobacillus stearothermophilus spores and nutrient media in a plastic vial. Device placed in sterilizer; post-cycle, BI inserted into Celerity HP Incubator. Reporter enzyme produced by surviving spores reacts with fluorogenic substrate in media to produce fluorescent signal. Incubator detects fluorescence within 5 minutes. Provides rapid confirmation of sterilization process efficacy; enables healthcare providers to verify sterilization cycle success before releasing instruments for clinical use.

Clinical Evidence

No clinical data. Bench testing only. Performance testing included 'All Survive' testing (all samples survived 4-second exposure) and comparative dose-response testing against a biological model, confirming equivalent or greater resistance than the biological model.

Technological Characteristics

Biological indicator containing Geobacillus stearothermophilus spores (1.0–4.0 x 10^6/BI) and nutrient media in a plastic vial. Sensing principle: enzymatic reaction with fluorogenic substrate producing fluorescent moiety. Requires Celerity HP Incubator for automated optical detection. Shelf-life: 8 months. Sterilization resistance: D-value ≥ 6 sec at 9.1 mg/L H2O2.

Indications for Use

Indicated for routine monitoring of vapor phased hydrogen peroxide sterilization cycles in specified V-PRO and STERRAD sterilization systems.

Regulatory Classification

Identification

Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device.

Dear Logan Persons:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

## 6. Summary of Non-clinical Tests

Testing was performed to evaluate performance of the subject device as compared to the predicate as summarized in Table 2.

Table 2. Performance Testing

| Test | Acceptance Criteria | Result |
| --- | --- | --- |
| All Survive Testing | All samples will survive a 4 second exposure | PASS |
| Comparative dose response to the biological model | The BI must show equivalent or greater resistance to the sterilization cycle (a greater percentage of BI growing after exposure) than the biological model.
