Device Description

Celerity 5 HP BI
The product is intended to monitor the vapor phased hydrogen peroxide sterilization cycles described in the indications for use. It produces an optical change (signal) that is detected by the STERIS proprietary reader, STERIS Celerity Incubator, within 5 minutes to confirm the viability of the biological indicator at the end of a sterilization process. The product consists of Geobacillus stearothermophilus spores and a defined nutrient media in a plastic vial. A reporter enzyme, which is produced by the organism, reacts with a fluorogenic substrate within the defined nutrient media to produce a fluorescent moiety.

Celerity 5 HP Challenge Pack
The Celerity 5 HP Challenge Pack is used in the sterile processing department, usually by service technicians or biomedical technicians to qualify the unit following installation, relocation, malfunctions or major repairs and for routine requalification testing. It consists of a Celerity 5 HP Biological Indicator, a Celerity HP Chemical Indicator, and a layer of absorptive foam within a Tyvek pouch.

The intended change to the devices is to update the secondary container and product labeling. Specifically, the clear cellophane wrapper around the product carton will be replaced by a clear, laminated pouch. Labeling on the carton and the Instructions for Use (IFU) will be updated to specify that the product must remain stored in its original laminated pouch to maintain the claimed shelf-life. Additionally, a storage disclaimer label will be added to the exterior of the pouch to notify users of this change. Finally, this submission is intended to establish a 3-month in-use shelf-life following pouch opening, not to exceed the original expiration date.

AI/ML Overview

The provided text describes premarket notification for biological indicators and doesn't involve an AI/ML powered medical device. Therefore, many of the requested criteria, such as "multi-reader multi-case (MRMC) comparative effectiveness study" or "number of experts used to establish ground truth", which are specific to AI/ML powered devices, are not applicable here.

However, I can extract information related to the acceptance criteria and the study proving the device meets those criteria, as much as applicable for a non-AI medical device.

Device: Celerity 5 HP Biological Indicator (LCB052) & Challenge Pack (LCB059), and Celerity 20 HP Biological Indicator (LCB044) & Challenge Pack (LCB045)

Type of Device: Sterilization Process Indicator (Biological Indicator - BI). These devices contain a specific type of spore (Geobacillus stearothermophilus) and media to confirm the effectiveness of a sterilization process. A positive result (fluorescent signal) indicates sterilization failure, while a negative result indicates successful sterilization.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria and results are provided for two distinct product lines: Celerity 5 HP and Celerity 20 HP. Note that the "Result" for all tests is simply "PASS", indicating that the criteria were met.

For Celerity 5 HP Biological Indicator and Challenge Pack:

Test	Acceptance Criteria	Result
Reduced Incubation Time Testing	All BI lots will demonstrate 97% or greater positive growth results at 7 days as compared to the fluorescent result at less than or equal to 5-minutes	PASS
Simulated Use Testing	All processed BIs shall be sterile following full cycle exposure sterilizer cycles.	PASS
Cap Media Testing	All BIs will demonstrate a positive fluorescent signal in the fluorescent incubators.	PASS
Stability Testing: Population	The mean initial population at the start of the stability study must be 1.0-4.0 x 10⁶ CFU/BI. At each subsequent time point, the mean population shall be 50-300% of the initial mean population.	PASS
Stability Testing: D-value	D-value between 6 and 20 seconds.	PASS
Stability Testing: Survival/Kill	Demonstration of one all survive time and one all kill time point.	PASS
Stability Testing: RIT	All BI lots will demonstrate 97% or greater positive growth results at 7 days as compared to the fluorescent result at less than or equal to 5 minutes.	PASS
Stability Testing: Media Testing	All BIs will demonstrate a positive fluorescent signal in the fluorescent incubators.	PASS

For Celerity 20 HP Biological Indicator and Challenge Pack:

Test	Acceptance Criteria	Result
Reduced Incubation Time Testing	All BI lots will demonstrate 97% or greater positive growth results at 7 days as compared to the fluorescent result at less than or equal to 20 minutes	PASS
Simulated Use Testing	All processed BIs shall be sterile following full cycle exposure sterilizer cycles.	PASS
Cap Media Testing	All BIs will demonstrate a positive fluorescent signal in the fluorescent incubators.	PASS
Stability Testing: Population	The mean initial population at the start of the stability study must be 1.0-4.0 x 10⁶ CFU/BI. At each subsequent time point, the mean population shall be 50-300% of the initial mean population.	PASS
Stability Testing: D-value	D-value between 6 and 20 seconds.	PASS
Stability Testing: Survival/Kill	Demonstration of one all survive time and one all kill time point.	PASS
Stability Testing: RIT	All BI lots will demonstrate 97% or greater positive growth results at 7 days as compared to the fluorescent result at less than or equal to 20 minutes.	PASS
Stability Testing: Media Testing	All BIs will demonstrate a positive fluorescent signal in the fluorescent incubators.	PASS

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the numerical sample size (e.g., number of BIs or challenge packs) used for each specific test (Reduced Incubation Time, Simulated Use, Cap Media, Stability testing). It refers to "All BI lots" for Reduced Incubation Time and "All processed BIs" for Simulated Use, and implicitly "BIs" for Stability Testing. This suggests a statistically relevant number of units from manufactured lots were tested.

Data Provenance: The document does not specify the country of origin of the data. Given the "U.S. Food & Drug Administration" letterhead and the manufacturer's address in Ohio, USA, it is highly likely that the testing was conducted in the US.
Retrospective or Prospective: The testing appears to be prospective as it's a pre-market submission to demonstrate the device meets performance criteria for clearance. Stability testing also inherently involves prospective observation over time.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

This concept is not applicable to this type of device. The "ground truth" for a biological indicator is determined by the biological and chemical reactions themselves (i.e., presence or absence of viable spores, or a color change in the chemical indicator), not by human expert interpretation of images or data. The determination of "sterile" or "non-sterile" from a biological indicator is a direct, objective measurement.

4. Adjudication Method for the Test Set

Not applicable. As noted above, the results of biological indicators are typically objective and determined by the physical/chemical properties and reactions, not by subjective human interpretation requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is not an AI/ML device nor one that involves human "readers" interpreting medical images or data.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. This is a physical, biological and chemical indicator device, not a software algorithm. The "Celerity Incubator" is an accessory that reads the fluorescent signal, it is not an AI algorithm.

7. The Type of Ground Truth Used

The ground truth for these devices is based on biological viability (presence or absence of viable Geobacillus stearothermophilus spores) for the biological indicator and chemical reaction (color change) for the chemical indicator, validated against recognized sterilization parameters (e.g., D-value, Survival Time, Kill Time). This is a direct measure of the effectiveness of the sterilization process.

8. The Sample Size for the Training Set

Not applicable. These are not AI/ML devices that require training sets. The "training" of these devices (i.e., their manufacturing and design) is based on established microbiological and sterilization science.

9. How the Ground Truth for the Training Set was Established

Not applicable, as there is no "training set" in the context of an AI/ML algorithm. The performance of these biological indicators relies on their inherent design and manufacturing quality, ensuring the spores exhibit the specified resistance characteristics and the media accurately detects their viability. This is established through rigorous quality control and adherence to relevant standards for biological indicators.
