Device Description

The AMSCO 600 Steam Sterilizer uses saturated steam, generated from a house steam utility (e.g. boiler system) or from a steam generator, to sterilize heat-stable health care products.
The V-PRO Low Temperature Sterilization System is a vaporized hydrogen peroxide sterilizer. It has the following pre-programmed cycles (the Lumen Cycle, the Non Lumen Cycle, the Flexible Cycle and the Fast Non Lumen Cycle). The V-PRO Low Temperature Sterilization System is intended for terminal sterilization of cleaned, rinsed, dried and packaged reusable surgical instruments used in healthcare facilities.
The V-PRO s2 Sterilizer executes four sterilization cycles (the Lumen, Non Lumen, Flexible Cycles and Fast Cycle). The V-PRO s2 Sterilizer contains a cabinetry modification and is free-standing.
The RAS Racks are designed to enable the mechanical cleaning, rinsing, and disinfection of up to twelve (12) robotic-assisted surgery instruments in a compatible washer-disinfector.
The V-PRO s2 Sterilizer executes four sterilization cycles (the Lumen, Non Lumen, Flexible Cycles and Fast Cycle). The V-PRO s2 Sterilizer contains a cabinetry modification and is free-standing.

AI/ML Overview

The provided FDA 510(k) summary describes several sterilization and washer-disinfector systems. The acceptance criteria and testing detailed are for modifications related to component obsolescence (oscillator replacement, coin cell battery to super capacitor, flash memory component alternates and associated software updates). The document does not describe a study related to AI or human-in-the-loop performance. Therefore, questions related to expert consensus, MRMC studies, effect size, and standalone algorithm performance are not applicable.

Here's an analysis of the acceptance criteria and supporting studies for the component modifications across the various devices:

1. Table of Acceptance Criteria and Reported Device Performance

Across all devices (AMSCO 600 Steam Sterilizer, V-PRO maX 2, V-PRO s2, V-PRO 60 Low Temperature Sterilization Systems, and RAS Racks/Cycle), the acceptance criteria and performance for the specific modifications are consistent:

Test	Acceptance Criterion	Reported Device Performance
½ Cycle sterility assurance Test (for Sterilizers)	All biological indicators must show no growth after a ½ Cycle exposure with a worst-case load.	Pass
Critical parameters test (for RAS Racks/Cycle)	Compare the cycle data of RAS cycle between modified and new Kodiak controllers to confirm the cleaning efficiency.	Pass
Software test	Verify sterilizer can set and read RTC, bootloader can load and run software application and verify proper operation of applications using serial flash.	Pass
Software confirmation test (for RAS Racks/Cycle)	Ensure proper version, proper parameters are in the cycles for proper operation of cycles.	Pass

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

The document does not explicitly state the specific sample sizes (e.g., number of cycles, number of biological indicators) used for these non-clinical performance tests. It refers to "worst-case load" for the sterility assurance tests.

The provenance of the data is non-clinical performance testing conducted by the manufacturer, STERIS Corporation. The country of origin is implicitly the United States, given STERIS's address in Mentor, Ohio, and the FDA submission. The studies are retrospective in the sense that they are proving the modified device performs equivalently to the original validated design.

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

This question is not applicable as the studies described are non-clinical performance tests verifying device functionality and sterility/cleaning efficacy, not diagnostic or interpretive tasks requiring human expert ground truth. The "ground truth" for these tests is defined by established sterilization and cleaning standards (e.g., "no growth" for biological indicators, confirmed cleaning efficiency).

4. Adjudication Method for the Test Set

This question is not applicable for non-clinical performance tests. The results (e.g., growth/no growth, successful software operation) are typically objective and determined by laboratory analysis or automated system checks.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document explicitly states that the modifications "has no impact on the device performance" compared to the predicate device because the changes are related to component obsolescence, not a change in the fundamental operating principle or intended use that would require a comparison of human reader effectiveness.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

This question is not applicable. The devices are sterilization and cleaning equipment, not algorithms that perform diagnostic or interpretive functions. The software tests performed are focused on verifying the proper functioning of the embedded system software controlling the sterilizers/washer-disinfectors, not standalone interpretive performance.

7. The Type of Ground Truth Used

The ground truth used for these non-clinical tests is based on:

Biological indicator results: "No growth" post-sterilization, indicating successful killing of microorganisms. This is a direct measure of sterility.
Physical and chemical parameters verification: Ensuring cycle data (time, temperature, pressure, sterilant injection weight) for sterilizers and cleaning/thermal disinfection parameters for the washer-disinfector (temperature, time, chemical dosing, pump pressure) meet pre-defined specifications.
Software functionality: Verification that the embedded software correctly sets and reads Real-Time Clock (RTC), loads and runs applications, and ensures proper operation using serial flash memory.
Cleaning efficiency: For the RAS Racks/Cycle, comparison of cycle data between modified and original controllers to confirm equivalent cleaning efficiency.

These "ground truths" are derived from validated operational parameters and expected biological/physical outcomes inherent to sterilization and cleaning processes, as per industry standards and internal validation protocols.

8. The Sample Size for the Training Set

This question is not applicable. These are hardware/software modifications to existing medical devices, not AI/ML algorithms that require a separate training set. The "associated software updates" are to accommodate new hardware components (flash memory, super capacitor) and ensure the existing validated sterilization/cleaning cycles continue to operate as intended.

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

This question is not applicable, as there is no "training set" in the context of these device modifications.

2. Predicate Device

K222543 AMSCO 600 Steam Sterilizer, V-PRO maX 2 and s2 Low Temperature Sterilization Systems, RAS 12 Rack, RAS 12 Long Rack, RAS Cycle of the AMSCO 7052HP and 7053HP Single Chamber Washer Disinfector

3. Description of Device

The AMSCO 600 Steam Sterilizer uses saturated steam, generated from a house steam utility (e.g. boiler system) or from a steam generator, to sterilize heat-stable health care products.

The sterilizer accomplishes this by removing the air in the chamber, exposing the load to saturated steam for a defined combination of time and temperature, and drying the load. Removal of air from the chamber occurs using either of two methods, gravity displacement or mechanical vacuum. Once the air removal phase is completed, the sterilizer progresses to the steam exposure phase. During the steam exposure phase, every surface of the load is exposed to saturated steam for a defined combination of time and temperature. Once the steam exposure phase is completed, steam is removed from the chamber and the load is dried using the latent heat in the load and the vacuum pump.

The sterilizers are generally operated by technicians in a central service or sterile processing department of healthcare facilities. Sterilizers may also be located in a surgical suite to allow for Immediate Use Steam Sterilization (IUSS) for instances where an instrument is needed immediately for a procedure (e.g. after an instrument has been dropped and there is no replacement readily available). Standard practices for use of sterilizers in health care facilities are provided by various organizations (e.g. ANSI/AAMI ST79).

The ALUS is used with the AMSCO 600 Steam Sterilizer's existing transfer carriages and loading carts. It consists of a conveyor system which attaches to the load and/or unload ends of the steam sterilizer. It has a series of barcode labels which correspond to pre-programmed cycles and an optional scanner which when fitted to the system will communicate to the sterilizer which cycle to initiate.

3. Device Description

The RAS Racks are designed to enable the mechanical cleaning, rinsing, and disinfection of up to twelve (12) robotic-assisted surgery instruments in a compatible washer-disinfector. Twelve soiled da Vinci X/Xi and S/Si Endowrist® instruments, with limited prior manual pre-cleaning, are loaded into the appropriate RAS Rack according to the provided instructions for use. The rack is placed in the AMSCO 7052HP or 7053HP Single-Chamber Washer/Disinfector, and the RAS Cycle is selected.

The RAS Cycle performs automated cleaning through a validated series of spraywashing, lumen flushing steps that use Prolystica Ultra Concentrate HP Enzymatic Cleaner alternately with Prolystica Ultra Concentrate HP Neutral Detergent in temperature-controlled solutions. When the series of automated prewash and washing stages are complete, a one-minute rinse occurs. Next the RAS Cycle completes a thermal rinse to achieve intermediate level disinfection of the load before drying it. Upon RAS Cycle completion, the devices are ready to be prepared and packed for steam sterilization.

4. Indications for Use

The RAS Racks are used in the RAS Cycle of the AMSCO 7052HP Single-Chamber Washer/Disinfector and the AMSCO 7053HP Single-Chamber Washer/Disinfector for the effective cleaning, rinsing, intermediate level disinfection and drying of reusable da Vinci® X/Xi and S/Si EndoWrist® instruments.
