The enspire™ 300 Series Automated Endoscope Reprocessor System is intended to effectively provide a pressure and channel monitor, clean, high-level disinfect, rinse and air purge validated immersible, reusable, semi-critical, heat sensitive medical devices including, but not limited to, flexible endoscopes and non-channeled naso-endoscopes. The validated cleaning process replaces manual cleaning for endoscopes other than duodenoscopes. Manual Cleaning of endoscopes is required prior to placement in high level disinfection only cycle.

The enspire 300 Series Automated Endoscope Reprocessor System uses Revital-Ox PAA High Level Disinfectant to provide high level disinfection of validated immersible, reusable, semi-critical, heat sensitive medical devices. It automatically mixes the Part B solutions, high level disinfects the load during a controlled cycle and rinses the load. The wash phase of the enspire 300 Series Automated Endoscope Reprocessor System cycle uses only Revital-Ox 2X Concentrate Enzymatic Detergent to perform cleaning.

The Revital-Ox PA High Level Disinfectant (HLD) is a two-part solution, which when mixed, is intended to provide high level disinfection of validated immersible, semi-critical, heat sensitive medical devices including, but not limited to, flexible endoscopes and non-channeled nasoendoscopes, when used in the enspire 300 AER.

The enspire 300™ Series Automated Endoscope Reprocessor (AER) is a medical device processing system used for cleaning and high level disinfection of immersible, reusable, semi-critical, heat-sensitive devices such as flexible endoscopes and their accessories. The system consists of the enspire 300 AER. Revital-Ox 2X Concentrate Enzymatic Detergent (R2X), and Revital-Ox Peracetic Acid High Level Disinfectant.

The enspire 300 series AER is an automated, self-contained device for the effective cleaning and high level disinfection of semi-critical medical devices and their accessories. Prior to placement in the processor, users will be instructed to perform bedside (point of use) cleaning and manual leak testing. The devices will not require manual pre-cleaning prior to processing, with the exception of duodenoscopes which will still require manual cleaning per the manufacturer's written instructions. Channel Connectors, as identified in STERIS labeling, are used to facilitate the delivery of the R2X detergent, HLD solution and rinse water to internal channels of devices that have them.

On the first process of an endoscope, the user must create a scope profile for the endoscope in the AER. The creation of the scope profile saves key endoscope attributes to the AER which are used to monitor the cycle during processing of the device. Once the device is positioned in the enspire 300 AER and optional operator ID, case ID, procedure ID and physician information is inputted, the operator initiates the processing cycle during which the Processor will create and maintain the conditions necessary for effective cleaning and high level disinfection. At the beginning of the processing cycle, an automated pressure monitor is performed to confirm the integrity of the flexible endoscope. In parallel with the pressure monitor and prior to initiation of the cleaning phase, the processing system will evaluate the flow coefficient of each individual channel and compare to their respective reference value stored in the device profile created prior to first processing. The enspire 300 AER maintains inflation of the processed device throughout the process to prevent ingress of fluid in the event of any loss of integrity. At the end of the processing cycle, the cleaned and high level disinfected devices are rinsed with 0.2 micron filtered potable water followed by a dried, oil free, filtered compressed air purge to evacuate rinse water from the endoscope channels. The AER, which is micro-processor controlled and continually monitored, provides documentation of each cycle.

The enspire 300 AER utilizes Revital-Ox 2X Concentrate Enzymatic Detergent for cleaning and Revital-Ox Peracetic Acid High Level Disinfectant for high level disinfection. Revital-Ox PAA HLD is a two part solution consisting of Part A, 15% PAA, and Part B, conditioner.

The document discusses an Automated Endoscope Reprocessor (AER) and its comparison to a predicate device, focusing on non-clinical testing. Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance:

Note: This table is directly extracted from the provided text. The "modified device" refers to the enspire 300 Series AER with new support material for its pre-filters.

2. Sample size used for the test set and the data provenance:

The document does not explicitly state the sample size used for the performance testing with replacement pre-filters. It also does not specify the data provenance (e.g., country of origin, retrospective or prospective nature). The testing is described as "new testing" performed to evaluate the modified device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not provided in the document. The testing described is performance testing of a medical device, which typically involves engineering and microbiology evaluations, not expert review for ground truth in the way it might be for an AI model interpreting medical images.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

This information is not applicable and not provided. Adjudication methods like 2+1 or 3+1 are typically used in studies involving human interpretation (e.g., radiologists interpreting images) to establish a consensus ground truth. This document describes performance testing of an automated reprocessing device, which doesn't involve such human interpretive 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:

This is not applicable as the device is an Automated Endoscope Reprocessor, not an AI-assisted diagnostic or interpretive system. Therefore, no MRMC study or effect size related to human readers improving with AI assistance would have been conducted or reported here.

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

The device itself is a "standalone" automated system for reprocessing endoscopes. The described "Performance testing with replacement pre-filters" evaluates the device's functional performance in this automated capacity. There isn't an "algorithm only" aspect in the sense of a software-based diagnostic tool, but rather the overall automated operation of the mechanical and chemical processes.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

For the "Performance testing with replacement pre-filters," the ground truth implicitly refers to the established performance requirements for an Automated Endoscope Reprocessor (e.g., effective cleaning and high-level disinfection, proper fluid delivery, temperature control, etc., as detailed in the "Description of Device" and "Process Monitors" sections). The acceptance criterion "The modification does not affect the performance of the device" implies that the device's ability to meet these established functional and safety parameters, which would be verified through specific engineering and potentially microbiological tests, serves as the ground truth. It's not a ground truth derived from expert consensus on interpretations or patient outcomes data directly from this specific test.

8. The sample size for the training set:

This information is not applicable. The device is a physical medical device (Automated Endoscope Reprocessor), not a machine learning or AI model that requires a training set.

9. How the ground truth for the training set was established:

This information is not applicable since there is no training set for this type of device.
