Intended Use

Use the Celerity Incubate and automatically read STERIS Celerity Biological Indicators for Steam and Vaporized Hydrogen Peroxide sterilization at 55°C - 60°C for a fluorescent result.

Device Story

Celerity Incubator is a benchtop device for incubating and reading fluorescent biological indicators (BIs) used in steam and vaporized hydrogen peroxide sterilization. The device features 8 wells arranged in 2 banks of 4, maintained at 59°C. Operation involves scanning the BI barcode, which triggers the system to apply the appropriate algorithm. The device uses UV LEDs to excite fluorescent molecules produced by enzymatic activity (a-glucosidase) within the BI, with a photodiode detecting the emitted light. Results are displayed via LCD screen, LED indicators (red for positive/failure, green for negative), and audible alarms. The device provides automated, rapid readout (5 or 20 minutes depending on the BI) to confirm sterilization cycle effectiveness. It is intended for use in clinical settings to assist healthcare providers in monitoring sterilization processes.

Clinical Evidence

Bench testing only. Performance was validated by comparing the fluorescent readout of the Celerity Incubator against 7-day growth out methods per FDA guidance. Results demonstrated >97% alignment for intended biological indicators. Additional testing included human factors validation, electromagnetic compatibility (IEC 60601-1-2:2014), electrical safety (IEC 61010-1), and software validation (IEC 62304).

Technological Characteristics

Benchtop incubator with 8 wells; 100-240 VAC power with 12 VDC conversion; UV LED excitation source; photodiode detection; factory-calibrated; operates at 59°C (-4°C/+1°C tolerance); barcode scanner input; LCD/LED/audible alarm output; software-controlled.

Indications for Use

Indicated for use by healthcare personnel to incubate and automatically read STERIS Celerity Biological Indicators for Steam and Vaporized Hydrogen Peroxide sterilization processes at 55°C - 60°C to detect fluorescent results indicating sterilization cycle efficacy.

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 Gregory Land:

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 (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 located 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
