The summary describes a standard sterilization device with pre-programmed cycles and performance testing based on microbiological principles, with no mention of AI or ML.
No
The device is a sterilizer for medical devices, not a therapeutic device used to treat or diagnose patients.
No
Explanation: The device is a sterilizer for medical equipment, not a diagnostic tool. Its function is to kill microorganisms on reusable medical devices, not to diagnose medical conditions.
No
The device description clearly states it is a "self-contained standalone device, using vaporized hydrogen peroxide as the sterilant," indicating it is a physical hardware device. While software validation is mentioned, it is validation for software contained within the hardware device, not a standalone software-only device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as "terminal sterilization of cleaned, rinsed and dried reusable metal medical devices used in healthcare facilities." This describes a process applied to medical devices themselves, not a test performed on biological samples to diagnose or monitor a condition.
- Device Description: The device description details a sterilizer that uses vaporized hydrogen peroxide to sterilize medical devices. This aligns with the intended use and does not involve the analysis of biological samples.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing diagnostic information
- Measuring analytes
- Using reagents for testing
The device is a sterilizer, which is a type of medical device used to prepare other medical devices for use. It does not fit the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Sterilucent HC 80TT Hydrogen Peroxide Sterilizer is a vaporized hydrogen peroxide sterilizer intended for use in the terminal sterlization of cleaned, rinsed and dried reusable metal medical devices used in healthcare facilities. The two pre-programmed sterilization cycles, the Lumen Cycle and the Flexible Cycle, operate at low temperature and are thus suitable for processing medical devices that are sensitive to heat and moisture.
The HC 80TT Lumen Cycle can sterilize:
o Lumen and non-lumen medical devices with diffusion-restricted spaces or mated surfaces such as the hinged portion of forceps and scissors;
O Single or dual channeled rigid and semi-rigid endoscopes, with stainless steel lumens that are:
- · ≥ 0.77 mm internal diameter (ID) and ≤ 410 mm long, or
- · ≥ 1.33 mm ID and ≤ 430 mm long; and,
o Triple channeled rigid and semi-rigid endoscopes, with stainless steel lumens that are: - ≥ 1.00 mm ID and ≤ 310 mm long.
The validation testing for all lumen sizes was conducted using a maximum of fifteen (15) Jumens per load. Hospital loads should not exceed the maximum number offumens validated by this testing. The validation studies were performed using two(2) separate validation loads as described in the following table.
The HC 80TT Flexible Cycle can sterilize:
- · Rigid or semi-rigid non-lumen medical devices including non-lumen devices with metallic diffusion-restricted spaces such or mated surfaces such as the hinged portion of forceps or scissors;
- · Single channel flexible endoscopes with flexible Iumens that are:
- · ≥ 1.00 mm ID and ≤ 1280 mm long; and,
- · Dual channel flexible endoscopes with flexible Iumens that are:

Device Description
The Sterilucent HC 80TT Hydrogen Peroxide Sterilizer (HC 80TT) is a self-contained standalone device, using vaporized hydrogen peroxide as the sterilant. The HC 80TT is intended for use in the terminal sterilization of cleaned, rinsed, and dried, reusable metal and non-metal medical device used in healthcare facilities. The sterilization cycle operates at low pressure and temperatures and is therefore suitable for processing medical devices that are sensitive to heat and moisture. The hydrogen peroxide vapor is generated by heating aqueous hydrogen peroxide and injecting into a chamber.

Pre-Validation Testing
Test Organism: Geobacillus stearothermophilus
Process Variables and Parameters Testing was conducted to characterize the effect of process parameters on lethality. The four critical process parameters are chamber wall temperature, vaporizer temperature, injection pressure and vaporized hydrogen peroxide concentration. The level tested for each parameter was selected to provide a worst-case situation for the test series and to be outside the abort levels or settings for the sterilizer. The study showed that process lethality was unaffected over the range of tested process parameters.
HC 80TT Sterilization Process Validation Demonstration of Dose-Response Relationship to Increasing Hydrogen Peroxide Concentration
Dose response testing was performed using various materials (representative of materials used in medical devices) as spore carriers. Geobacillus stearothermophilus death kinetics data obtained for each material tested demonstrate a positive "dose response" to increasing concentration of hydrogen peroxide injected under half cycle conditions in the HC 80TT.
Surface Sterilization
Geobacillus stearothermophilus spores were inoculated on a wide variety of material coupons that were representative of materials used in reusable medical devices. The coupons were inoculated with at least 106 Geobacillus stearothermophilus spores and then exposed to ½ cycle sterilization parameters.
Mated Surface Sterilization
Geobacillus stearothermophilus spores were inoculated on a variety of medical device materials. The materials were than mated to the same material and exposed to ½ cycle sterilization parameters.
Lumen Sterilization
Testing was completed by placing at least 10° Geobacillus stearothermophilus spores in the center of the lumens and exposing them to ½ cycle sterilization parameters.
Simulated Use Testing
Representative lumen and non-lumen devices were inoculated with at least 10-6 Geobacillus stearothermophilus spores, suspended in an inorganic and organic challenge soil and exposed to a full sterilization cycle.
In-Use Testing
Devices representative of surface features and lumen claims for the HC 80TT were selected for sterility testing. Devices including stainless steel devices with open surfaces, mated or hinged surfaces, representative stainless steel lumen devices, and representative flexible scopes were soiled with clinical soils. The soiled devices were manually cleaned and/or washed per the Manufacturer's Instructions for Use, dried, packaged and processed in the applicable HC 80TT cycle (Lumen or Flexible).
Supporting Microbiological Testing
Sterilizing agent efficacy (Sporicidal Activity of a Disinfectant) testing was performed in the HC 80TT in accordance with the guidelines provided in AOAC Official Method 966.04, Sporicidal Activity of Disinfectants.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Testing (Bench): The HC 80TT sterilization cycle parameters have been shown to provide a level of safety and efficacy at least equivalent to that of the predicate device. Testing was performed using the "overkill" method.
Pre-Validation Testing: The study showed that process lethality was unaffected over the range of tested process parameters.
HC 80TT Sterilization Process Validation Demonstration of Dose-Response Relationship to Increasing Hydrogen Peroxide Concentration: There were no spore survivors on any material at concentrations lower than the standard exposure concentration for the Lumen and Flexible Cycles. The result demonstrates that the dose response observed is not limited to a single substrate and in each case >6 Spore Log Reduction (SLR) was observed for a half cycle exposure.
Surface Sterilization: Results from this testing demonstrate a Sterility Assurance Level (SAL) of at least 10-6 for medical device surface sterilization in the HC 80TT for all materials listed as recommended for use in the HC 80TT.
Mated Surface Sterilization: An SAL of least 10° was demonstrated for mated material sterilization.
Lumen Sterilization: There were no spore survivors after multiple ½ cycle exposure tests. Results from this testing demonstrate an SAL of at least 10-6 for lumen sterilization in the HC 80TT for the lumen dimensions listed as indicated for use in the HC 80TT.
Simulated Use Testing: The results showed sterility of all tested devices.
In-Use Testing: The results of the in-use testing demonstrated that the HC 80TT successfully sterilizes surgical instruments used in clinical settings.
Supporting Microbiological Testing: None of the carriers demonstrated growth.

Comparison to the Both the HC 80TT and the predicate device have the same: Predicate device: . Intended use Processes validated to a Sterility assurance level (10-6) ● . Sterilant The HC 80TT design differs slightly from the predicate; the HC 80TT is slightly smaller and lighter that the PSD-85. Using the Lumen Cycle, the HC 80TT can sterilize single-, dual-, or triplechanneled rigid and semi-rigid endoscopes with stainless steel lumens as specified in the Indications for Use, while the PSD-85 is indicated to sterilize medical devices with only a single stainless-steel lumen of larger diameter and shorter length. The HC 80TT's "Flexible Cycle" and the PSD-85's "Non-Lumen Cycle'' both sterilize non-lumen instruments with diffusion-restricted spaces, but the HC 80TT is also indicated to sterilize single- and dual-channel flexible endoscopes. Performance Testing The HC 80TT sterilization cycle parameters have been shown to provide a (Bench): level of safety and efficacy at least equivalent to that of the predicate device. Testing was performed using the "overkill" method. Pre-Validation Testing Test Organism: Geobacillus stearothermophilus Process Variables and Parameters Testing was conducted to characterize the effect of process parameters on lethality. The four critical process parameters are chamber wall temperature, vaporizer temperature, injection pressure and vaporized hydrogen peroxide concentration. The level tested for each parameter was selected to provide a worst-case situation for the test series and to be outside the abort levels or settings for the sterilizer. The study showed that process lethality was unaffected over the range of tested process parameters. HC 80TT Sterilization Process Validation Demonstration of Dose-Response Relationship to Increasing Hydrogen Peroxide Concentration Dose response testing was performed using various materials (representative of materials used in medical devices) as spore carriers. Geobacillus stearothermophilus death kinetics data obtained for each material tested demonstrate a positive "dose response" to increasing concentration of hydrogen peroxide injected under half cycle conditions in the HC 80TT. There were no spore survivors on any material at concentrations lower than the standard exposure concentration for the Lumen and Flexible Cycles. The result

demonstrates that the dose response observed is not limited to a single substrate and in each case >6 Spore Log Reduction (SLR) was observed for a half cycle exposure.
Surface Sterilization
The purpose of the study was to demonstrate sterilization of medical device surfaces. Geobacillus stearothermophilus spores were inoculated on a wide variety of material coupons that were representative of materials used in reusable medical devices. The coupons were inoculated with at least 106 Geobacillus stearothermophilus spores and then exposed to ½ cycle sterilization parameters.
Results from this testing demonstrate a Sterility Assurance Level (SAL) of at least 10-6 for medical device surface sterilization in the HC 80TT for all materials listed as recommended for use in the HC 80TT.
Mated Surface Sterilization
The purpose of the study was to demonstrate sterilization of mated medical device surfaces using the HC 80TT. Geobacillus stearothermophilus spores were inoculated on a variety of medical device materials. The materials were than mated to the same material and exposed to ½ cycle sterilization parameters. An SAL of least 10° was demonstrated for mated material sterilization.
Lumen Sterilization
The purpose of this validation test was to demonstrate that the HC 80TT could effectively sterilize specific dimensions of rigid stainless steel and flexible lumened medical devices. Testing was completed by placing at least 10° Geobacillus stearothermophilus spores in the center of the lumens and exposing them to ½ cycle sterilization parameters. There were no spore survivors after multiple ½ cycle exposure tests.
Results from this testing demonstrate an SAL of at least 10-6 for lumen sterilization in the HC 80TT for the lumen dimensions listed as indicated for use in the HC 80TT.
Simulated Use Testing
Simulated use testing was performed to confirm sterilization of medical device surfaces and lumens after processing in the HC 80TT. Representative lumen and non-lumen devices were inoculated with at least 10-6 Geobacillus stearothermophilus spores, suspended in an inorganic and organic challenge soil and exposed to a full sterilization cycle. The results showed sterility of all tested devices.
In-Use Testing
14
Devices representative of surface features and lumen claims for the HC 80TT were selected for sterility testing. Devices including stainless steel devices with open surfaces, mated or hinged surfaces, representative stainless steel lumen devices, and representative flexible scopes were soiled with clinical soils. The soiled devices were manually cleaned and/or washed per the Manufacturer's Instructions for Use, dried, packaged and processed in the applicable HC 80TT cycle (Lumen or Flexible). The results of the in-use testing demonstrated that the HC 80TT successfully sterilizes surgical instruments used in clinical settings.
Supporting Microbiological Testing
Sterilizing agent efficacy (Sporicidal Activity of a Disinfectant) testing was performed in the HC 80TT in accordance with the guidelines provided in AOAC Official Method 966.04, Sporicidal Activity of Disinfectants. None of the carriers demonstrated growth.
Software Validation
Software validation was performed according to FDA's moderate level of concern recommendations provided in the document "Guidance for the Content for Premarket Submissions for Software Contained in Medical Devices".
Conclusion:
The nonclinical tests that demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate device.
