The provided FDA 510(k) summary does not contain the specific details required to fully address all parts of your request regarding acceptance criteria and the study proving the device meets them. This document primarily focuses on demonstrating substantial equivalence to a predicate device, particularly regarding a software change. It indicates that most performance data relies on previous testing of the predicate device.

However, based on the information available, here's what can be extracted:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly present a table of acceptance criteria with corresponding reported device performance for the new software version. Instead, it discusses the purpose of the software change and states that testing was performed to ensure it works as intended and does not impact safety and effectiveness.

The key change described in the software is:

• Previous Software (SW0021-281): User had the option to exceed the depth for bladder neck, mid-prostate, and median lobe. Purple lines on the GUI blinked when depth was exceeded. Maximum depth constraint could not let the user place markers beyond 24.3 mm.
• New Software (SW0021-282): Limits the user from planning a cut in profile path beyond the depth of the cut defined in the angle step for mid prostate and bladder neck. The purple line indicator flashing is removed as the user is now limited. The median lobe depth of cut is not limited. The maximum depth constraint is removed from the Profile Landmark step, allowing the user to place 4 landmark points beyond 24.3 mm depth, though the maximum planned depth remains 24.3 mm.

Implied Acceptance Criteria (based on the software change description):

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document states "The new software and operating system verification and validation testing to ensure that the software and the operating system changes do not impact the safety and effectiveness of the subject device and the subject device software and OS works as intended."

However, no specific sample size or details about data provenance (e.g., country of origin, retrospective/prospective) are provided for this software verification and validation testing. The document largely relies on the past performance data of the predicate device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not provided in the document. The document refers to "verification and validation testing" for the software without detailing who performed or reviewed these tests, or how ground truth was established within this context.

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

This information is not provided in the document.

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 information is not provided in the document. The device in question is a robotic system for prostate tissue removal, not an AI-assisted diagnostic imaging system that would typically involve human readers.

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

This information is not directly applicable or provided for this type of robotic surgical device. The software changes described are related to planning and constraints within the user interface of the robotic system, which inherently involves a human operator (surgeon). The verification and validation testing would assess the software's behavior in this human-in-the-loop context.

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

For the software changes, the "ground truth" would likely be the expected and specified behavior of the software as defined by the developers and engineers, validated through testing scenarios. It is not equivalent to clinical 'ground truth' from pathology or outcomes data in the usual sense for diagnostic devices. However, the document does mention "Clinical Trial Data" as pre-existing non-clinical data relied upon, implying that the overall safety and effectiveness of the system (of which the software is a component) has been supported by clinical outcomes in the past. Details of this clinical trial ground truth are not provided for this specific submission.

8. The sample size for the training set

This information is not provided in the document. While the software was verified and validated, there is no indication that it employs machine learning or AI that would require a "training set" in the typical sense. It appears to be a rule-based or algorithmic software update.

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

As there is no mention of a "training set" in the context of machine learning, this information is not provided and likely not applicable.

The HYDROS™ Robotic System is intended for the resection and removal of prostate tissue in males suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia.

The HYDROS™ Robotic System has three components - the HYDROS Robotic System, HYDROS TRUS Probe, and HYDROS Handpiece.

1. HYDROS Robotic System: consists of the HYDROS Tower, Touchscreen Interfaces Monitor, HYDROS Software, HYDROS Operating System, Embedded Software, Motorpack, Handpiece Arm, TRUS Probe Arm, and Foot Pedal. It is provided non-sterile and reprocessed per instructions. It does not contact patients during the procedure.
2. HYDROS TRUS Probe: a biplane transrectal ultrasound probe used with the HYDROS Robotic System and HYDROS Handpiece to provide ultrasound imaging for the AQUABLATION procedure. It is re-usable, provided non-sterile, and reprocessed prior to each use.
3. HYDROS Handpiece: a single-use sterile surgical device introduced through the urethra to visualize, resect and remove prostatic tissue. It is integrated with a digital CMOS Scope and terminally sterilized by EtO.

Here's a summary of the acceptance criteria and study information for the HYDROS™ Robotic System, HYDROS™ Handpiece, and HYDROS™ TRUS Probe, based on the provided text:

Important Note: The provided text is a 510(k) summary, which focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing. It does not contain information about a clinical study or performance metrics specifically for AI functionality, as the AI feature seems to be an optional "FirstAssist AI™" feature that aids in planning rather than directly dictating treatment. Therefore, many of the requested clinical study-related details are not available in this document.

1. Table of Acceptance Criteria and Reported Device Performance

The document primarily reports "Pass" for all non-clinical bench tests, indicating that the device met the requirements of the specified standards and guidance documents. Specific quantitative acceptance criteria or performance metrics beyond a "Pass" result are not provided in this summary.

Non-Clinical Testing Details:

• Study Type: Design validation included simulated use testing and cadaver testing. The summary primarily lists compliance with various national and international standards and FDA guidance documents.
• Sample Size (Test Set): Not explicitly stated in the provided text for each specific test. The "Pass" results suggest that the tests were conducted with sufficient samples to meet the requirements of the standards.
• Data Provenance: Not specified, but implied to be from laboratory and cadaver testing within the manufacturer's control, as it's non-clinical performance data.
• Number of Experts for Ground Truth & Qualifications: Not applicable for non-clinical bench testing.
• Adjudication Method: Not applicable for non-clinical bench testing.
• Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: Not mentioned in this non-clinical summary. The AI feature ("FirstAssist AI™") is described as "optional" and assists in planning by providing handpiece nozzle position and prostate capsule boundary, and placing profile landmarks for adjustment by the surgeon. This suggests it's a decision-support tool rather than an autonomous diagnostic or treatment device requiring MRMC studies for performance comparison against human readers.
• Standalone (Algorithm Only) Performance: The AI/ML entry indicates compliance with FDA guidance documents for CADe devices and good machine learning practice. This suggests standalone performance testing for the AI component was likely conducted to meet these guidelines, but specific metrics are not detailed in this summary. The AI assists in planning rather than directly performing the procedure.
• Type of Ground Truth (for AI): The AI feature provides "handpiece nozzle position and the prostate capsule boundary" and places "4 landmarks - treatment start (TS), bladder neck (BN), mid-prostate (MP) and treatment end (TE)." The implication is that these are derived from anatomical structures visible on TRUS imaging, and the ground truth for these would typically be established by expert review/annotations of such images.
• Sample Size for Training Set (for AI): Not specified in the provided text.
• How Ground Truth for Training Set was Established (for AI): Not explicitly stated. For AI in medical imaging, ground truth is typically established by expert annotation (e.g., urologists or radiologists marking anatomical structures or disease boundaries on medical images).

Conclusion from the document:
"The overall performance data in this submission supports that the HYDROS Robotic System and its components are substantially equivalent to the predicate device when utilized for its intended use." This statement confirms that all acceptance criteria relevant to demonstrating substantial equivalence through non-clinical means were met.

The provided text is a 510(k) summary for the AQUABEAM® Robotic System, which is intended for the resection and removal of prostate tissue. However, this document does not contain acceptance criteria or study data demonstrating the device meets specific performance criteria in the way that would typically be presented for an AI/ML medical device submission.

Instead, this 510(k) submission primarily focuses on:

• Device Description: What the AQUABEAM Robotic System is and how it works.
• Indications for Use: The medical conditions it is intended to treat.
• Technological Characteristics: Stating that these are unchanged from the predicate device.
• Device Comparison: Detailing changes only to the device labeling (specifically, to the contraindications section).
• Performance Data: Listing pre-existing non-clinical data (biocompatibility, sterilization, software/firmware verification, electrical safety, usability, system design validation, reliability testing) relied upon. This section does not outline new performance criteria or data related to the device's efficacy for tissue removal.
• Clinical Data Summary: Discussing a sub-group analysis from the WATER study (NCT02505919) and a study on circulating tumor cells (CTCs) in the context of the labeling change for contraindications, specifically regarding patients with diagnosed or suspected prostate cancer. This is to justify removing a contraindication, not to establish new performance metrics for the device's primary function of tissue removal.

Based on the provided text, the device in question is the PROCEPT BioRobotics AQUABEAM® Robotic System.

It's important to note that this document is a 510(k) summary for a Special 510(k), which means the device is being cleared as substantially equivalent to a previously cleared predicate device (AQUABEAM Robotic System 510(k) Number: K202961). The changes described are minor modifications related to sterility and the use life of a component. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are primarily focused on demonstrating that these minor changes do not compromise the safety and effectiveness established in the predicate device's clearance.

The document does not provide details of acceptance criteria or a study that proves the device meets initial acceptance criteria in the way one might expect for a de novo device or a PMA application. Instead, it relies on substantial equivalence to a predicate device and non-clinical testing to confirm that the changes made do not negatively impact performance.

Here's a breakdown of the requested information based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria and performance data for this Special 510(k) relate specifically to the changes made to the predicate device, primarily the sterilization method for the AQUABEAM Scope and its updated use life. The document asserts that the fundamental performance characteristics (e.g., maximum angle rotation, maximum depth of penetration) remain the same as the predicate.

Important Note: The original 510(k) for the predicate device (K202961) would contain the clinical trial data and design verification/validation testing that established the primary safety and effectiveness of the system for prostate tissue removal. This Special 510(k) is a supplement for minor changes.

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

• For the non-clinical testing described in this Special 510(k) (sterilization, biocompatibility, reliability of the scope): The document does not specify the sample sizes used for these specific tests (e.g., how many scopes were tested for sterility or reliability).
• For any pre-existing "Clinical Trial data" referenced from the predicate device: The specific sample sizes and data provenance for the clinical studies supporting the predicate device's original clearance are not provided in this document. The document simply states "Clinical Trial data" was performed on the predicate device and is still applicable.

3. Number of Experts Used to Establish Ground Truth and Qualifications of Experts

This document pertains to a device (AQUABEAM Robotic System) for prostate tissue removal, not an AI/imaging diagnostic device. Ground truth, in the context of this device, would typically refer to the clinical outcomes and validation of its physical performance during surgery, rather than a diagnostic AI's performance against expert-labeled images.

Therefore, the concepts of "number of experts used to establish ground truth for the test set" and "qualifications of those experts" are not applicable in the context of this device's regulatory submission as described here. The "experts" involved would be the clinical investigators and surgeons who participated in the clinical trials supporting the predicate device's clearance.

4. Adjudication Method (e.g., 2+1, 3+1, none) for the Test Set

As this is not an AI/imaging diagnostic device requiring expert adjudication of image interpretations, an adjudication method for a test set is not applicable in the context of this device's regulatory review as described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of Human Improvement with AI vs. Without AI Assistance

This is not applicable as the AQUABEAM Robotic System is a surgical device, not an AI or imaging diagnostic device where MRMC studies are typically performed.

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

This is not applicable for the same reasons as above. The device is a robotic surgical system, not an AI algorithm.

7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)

For the overall performance of the AQUABEAM Robotic System (as established by the predicate device's original clearance and affirmed by this Special 510(k)), the "ground truth" would be clinical outcomes data related to prostate tissue removal and improvement in LUTS due to BPH, potentially supported by pathology of removed tissue and confirmed through clinical follow-up.

For the specific non-clinical tests in this Special 510(k) (sterilization, biocompatibility, scope reliability), the "ground truth" is adherence to established engineering and biological standards (e.g., SAL of 10^-6 for sterility, passing cytotoxicity tests, meeting internal design specifications for cycles).

8. The Sample Size for the Training Set

This is not applicable. The AQUABEAM Robotic System is a hardware-based medical device for surgery. It is not an AI/machine learning model that requires a training set.

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

This is not applicable for the same reasons as #8.

The provided text describes the AQUABEAM® Robotic System and its substantial equivalence to a predicate device (DEN170024). It details various non-clinical tests performed to demonstrate this equivalence, but does not include information about acceptance criteria or a specific study proving the device meets those criteria in a quantitative manner (e.g., using specific metrics like sensitivity, specificity, accuracy with established thresholds).

The document focuses on verification testing to show that changes to the device (e.g., software, hardware) perform as intended and that the system remains substantially equivalent to the previously cleared predicate device.

Here's a breakdown of the information that is available, and what is missing based on your request:

1. A table of acceptance criteria and the reported device performance

The document provides a table of "Non-Clinical Testing" and "Conclusion" which states that "all acceptance criteria were met" for various categories. However, it does not explicitly define those acceptance criteria (e.g., "Software performed as intended" is a conclusion, not a measurable criterion with a numerical target). Therefore, a detailed table as requested cannot be constructed from the provided text.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document. The text mentions "cadaver study" for design validation, but doesn't specify sample size, origin, or retrospective/prospective nature.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not provided in the document.

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

This information is not provided in the document.

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 information is not applicable/not provided. The device is a robotic system for surgical resection, not an AI diagnostic or assistance tool for human readers in the context of image interpretation.

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

This information is not applicable/not provided. The device is a physical robotic system, not an algorithm in the typical sense of standalone AI performance.

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

For the system design validation, the document mentions a "cadaver study." While it doesn't explicitly state the "ground truth" for this cadaver study, it implies that the performance of the system in resecting prostate tissue on cadavers served as a proxy for validating its functionality. The nature of the ground truth (e.g., precise tissue removal confirmed by dissection or imaging) is not detailed.

8. The sample size for the training set

This information is not applicable/not provided. The device is a robotic system, not a machine learning model that undergoes a "training set."

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

This information is not applicable/not provided for the same reason as point 8.

Summary of available information related to acceptance criteria and performance:

The document states that a variety of non-clinical tests were performed on the AQUABEAM Robotic System to demonstrate substantial equivalence to its predicate device. For each category of testing, the conclusion is that "all acceptance criteria were met." However, the specific metrics and thresholds for these "acceptance criteria" are not detailed.

Here's what the document indicates regarding testing and conclusions:

Table of Acceptance "Criteria" (Implicit) and Reported Device Performance:

Additional relevant points from the text:

• Clinical Trial Data: "Existing clinical trial data is sufficient to establish the safety and effectiveness of the subject device, AQUABEAM Robotic System with the changes in design subject of this traditional 510(k) do not change the mode of operation/mechanism of action of the device." This indicates that previous clinical data for the predicate device, which shares the same indications for use and mechanism of action, is being leveraged, eliminating the need for new clinical trials for this specific 510(k) submission.
• The 510(k) submission is for changes to an existing, already cleared device, demonstrating substantial equivalence to its predicate (DEN170024). The focus is on showing that the changes do not negatively impact safety or effectiveness.
