## Indications for Use

Use the Celerity HP Incubator to incubate and automatically read Celerity 20 HP Biological Indicators at 57 °C for a fluorescent result within 20 minutes.

## Device Story

The Celerity HP Incubator is a benchtop reader/incubator used to monitor sterilization efficacy. It accepts Celerity 20 HP Biological Indicators (BIs) containing Geobacillus stearothermophilus. The device maintains a constant 57 °C temperature to facilitate enzyme-based outgrowth of the microorganisms. An internal photodiode detects fluorescence generated by enzyme cleavage of a substrate within the BI. The device features 8 incubation wells; users initiate the process by inserting a BI and pressing an 'ACTION' button. Results are displayed via front-panel LED lights (red for positive/failure, green for negative/pass), an audible alarm, and an LCD screen. Positive results indicate potential sterilization cycle failure, requiring operator acknowledgment. The device is intended for use by healthcare personnel to verify sterilization performance.

## Clinical Evidence

Bench testing only. Performance verification included electrical safety (UL 61010-1, UL 61010-2-010), electromagnetic compatibility (IEC 61326-1, FCC Part 15), and functional testing of alarms, LEDs, and output systems. All tests met established acceptance criteria.

## Technological Characteristics

Benchtop incubator/reader with 8 wells. Sensing principle: UV LED excitation and photodiode detection of fluorescence. Temperature range: 55-60 °C. Power: 100-240 VAC with 12 VDC conversion. Factory calibrated. Compliance: IEC 61010-1, IEC 61010-2-010, IEC 61326, FCC Part 15.

## Regulatory 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 Anthony Piotrkowski:

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

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

### 3. Reference Device

K173670 - Celerity 20 Steam Incubator

### 4. Description of Device

Celerity HP Incubator (Incubator) is an incubator/reader designed for use specifically with the Celerity 20 HP Biological Indicator (BI). The incubator/reader provides a constant temperature range to allow for activation and outgrowth of Geobacillus stearothermophilus which is detected by an enzyme that cleaves the a substrate leading to production of a fluorescent moiety. The presence of an increasing fluorescence signal due to increasing concentrations of this fluorescent moiety in the BI is detected by the incubator/reader and indicates the presence of viable test microorganisms.

### ട. Intended Use/ Indications for Use

Use the Celerity HP Incubator to incubate and automatically read Celerity 20 HP Biological Indicators at 57 ℃ for a fluorescent result within 20 minutes.

### 6. Summary of Technical Characteristics

Comparisons of technical characteristics versus the predicate and reference devices are summarized in Tables 5-1 and 5-2 respectively.
