There is no mention of AI models, machine learning, or deep neural networks in the description of the device's function or components.
No.
This device is designed to monitor and qualify sterilizers, ensuring they effectively sterilize other medical devices, rather than directly providing a therapeutic effect to a patient.
Yes
The device is a biological indicator and challenge pack used for monitoring and qualifying sterilization cycles. It provides a "fluorescent result" or "optical change (signal)" that indicates whether the sterilization process was successful, thus providing diagnostic information about the sterility of instruments rather than diagnosing a patient condition.
No
The devices are hardware-based biological and chemical indicators and a challenge pack for sterilizer monitoring. They consist of physical components like spores, nutrient media, plastic vials, foam, and Tyvek pouches. While they are used with an "Incubator" which likely contains software, the device itself is not software only, nor is it a software component. The submission explicitly details changes to physical packaging (pouches) and labeling, not software updates.

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.

10. Description of Device
Celerity 20 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 20 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 20 HP Challenge Pack
The Celerity 20 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 these 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.
