The provided text indicates that the K081129 submission for the "EnSeal PowerTip with EnSeal Universal" is a 510(k) premarket notification. This type of submission relies on demonstrating substantial equivalence to legally marketed predicate devices, rather than conducting new clinical studies with defined acceptance criteria and detailed performance reporting.

Therefore, the documentation does not contain the specific information requested in your prompt regarding acceptance criteria, a dedicated study proving device performance against those criteria, sample sizes, expert involvement, adjudication methods, MRMC studies, or standalone algorithm performance.

Here's what can be inferred from the provided text in relation to your request:

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

• Not Applicable. The submission is a 510(k) for substantial equivalence. It does not present new acceptance criteria or clinical performance data in this format.

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

• Not Applicable. No explicit "test set" in the context of a de novo clinical study is described. The device's safety and effectiveness are established by demonstrating functional similarities and preclinical testing in comparison to predicate devices.
• The provenance is "Preclinical laboratory (bench) and performance tests," suggesting in-house testing rather than human clinical data.

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

• Not Applicable. Ground truth, in the sense of expert consensus on clinical outcomes, is not established or reported for this type of submission.

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

• Not Applicable. No adjudication method is mentioned as there is no described test set requiring one.

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:

EnSeal™ PTC with ERBE VIO 300 D. The functionality of the device is the same as the predicate device.

The provided text is a 510(k) summary for the EnSeal™ PTC with ERBE VIO 300 D, an electrosurgical device. This document focuses on demonstrating substantial equivalence to predicate devices rather than conducting a de novo study with specific acceptance criteria as one might see for novel AI/software devices. Therefore, much of the requested information regarding acceptance criteria, specific performance metrics, sample sizes, expert involvement, and ground truth establishment, as typically outlined for AI/ML device studies, is not present in this type of submission.

Here's an analysis based on the provided text, highlighting what is and is not available:

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

Explanation: In a 510(k) for an electrosurgical device like this, acceptance criteria would typically revolve around electrical safety, mechanical integrity, and functional performance (e.g., sealing strength, cut time, minimal thermal spread) compared to the predicate. However, these specific criteria and quantitative results are not detailed in this summary. The summary simply states that the tests "ensure the devices function as intended and meet design specifications."

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

• Test Set Sample Size: Not specified. The document only mentions "Preclinical laboratory (bench) and performance tests."
• Data Provenance: Not specified. The tests were "preclinical laboratory (bench)" tests, suggesting an in-house or contracted lab environment, but geographical origin is not mentioned. They would be considered prospective for the specific tests conducted.

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)

• Number of Experts: Not applicable/Not specified. This type of device performance testing does not typically involve human experts establishing "ground truth" in the way a diagnostic imaging AI algorithm would. Device performance is measured by objective metrics (e.g., burst pressure, temperature).
• Qualifications of Experts: Not applicable/Not specified.

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

• Adjudication Method: Not applicable/Not specified. Adjudication methods like 2+1 or 3+1 are typically used for establishing consensus ground truth in studies involving human interpretation (e.g., reviewing medical images). This is a physical device, and its performance is measured mechanically and electrically, not through human consensus on a diagnosis.

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

• MRMC Study: No. This is not an AI/ML diagnostic device, so an MRMC study comparing human readers with and without AI assistance is not relevant and was not conducted.

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

• Standalone Study: The device itself is "standalone" in its electrosurgical function, but the context of "standalone performance" typically refers to an algorithm's performance without human intervention. This device performs its function directly. Therefore, this question is not fully applicable in the context of an AI/ML algorithm. The "Preclinical laboratory (bench) and performance tests" assess the device's inherent function, which could be considered its standalone performance.

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

• Type of Ground Truth: For electrosurgical devices, "ground truth" is established through engineering and scientific principles. Examples might include:
  • Physical measurements: Tensile strength of sealed vessels, burst pressure, impedance, power output.
  • Histopathology: To assess thermal damage zones in sealed tissue (though not mentioned in the summary).
  • Objective functional assessments: Such as sealing time, cutting efficacy, and lack of electrical leakage.
    The summary does not detail the specific ground truth metrics but states tests were performed to ensure it "function[s] as intended and meet[s] design specifications."

8. The sample size for the training set

• Training Set Sample Size: Not applicable. This is not an AI/ML device, so there is no "training set" in the machine learning sense.

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

• Ground Truth Establishment for Training Set: Not applicable. As there is no training set for an AI/ML model, this question does not apply.

Study Description:

The study proving the device meets its "acceptance criteria" (which are generally implied to be equivalent performance to the predicate) is described as "Preclinical laboratory (bench) and performance tests." The conclusion drawn from these tests is that the device "function[s] as intended and meet[s] design specifications" and is "safe and effective and substantially equivalent to the predicate device." The study's focus was on demonstrating substantial equivalence to the previously cleared devices (EnSeal™ Vessel Sealing and Hemostasis System # K031133, and the ERBE VIO ESU, Model VIO 300 D, # K060484 and EnSeal PTC # K061526). This type of submission relies on comparative analysis of technological characteristics and performance data, rather than establishing de novo safety and effectiveness through a comprehensive multi-site clinical trial with specific performance endpoints often seen for novel therapeutic or diagnostic devices.

EnSeal™ PTC Tissue Sealing Device. The functionality of the device is the same as the predicate device. The EnSeal™ electrosurgical instruments are the same as the predicate devices utilizing RF powered bipolar distal ends.

The provided text describes a 510(k) premarket notification for the EnSeal™ PTC Tissue Sealing Device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting extensive de novo clinical study data with acceptance criteria and detailed performance metrics as would be found in a PMA.

Therefore, the input does not contain the kind of detailed information about acceptance criteria and a study proving those criteria that your request anticipates for a medical device with an AI component or complex performance claims requiring extensive clinical validation. The document states "Preclinical laboratory (bench) and performance tests were executed to ensure the devices function as intended and meet design specifications." and "The EnSeal™ PTC Tissue Sealing Device is equivalent to the predicate device based on results of design validation." This suggests that the studies performed were primarily bench testing and design validation to show the new device operates similarly to the predicate, not a clinical trial with specific performance targets against a ground truth.

Given the available information, I cannot complete most of the requested fields. Here's what I can extract and what is missing:

1. Table of acceptance criteria and the reported device performance

The document does not explicitly state acceptance criteria in the format of a table with specific thresholds (e.g., sensitivity > X%, specificity > Y%). It broadly states that "Preclinical laboratory (bench) and performance tests were executed to ensure the devices function as intended and meet design specifications." This implies that the acceptance criteria were likely related to engineering specifications and functional equivalence to the predicate device, but these are not enumerated. The reported performance is a general statement of "design validation" demonstrating equivalence.

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

The document mentions "Preclinical laboratory (bench) and performance tests" but does not specify the sample size for these tests. There's no mention of a "test set" in the context of patient data, data provenance (country of origin), or whether the data was retrospective or prospective, as this device uses bench testing for clearance.

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

Not applicable. The clearance is based on bench testing and design validation against engineering specifications and predicate device performance, not clinical interpretation against a ground truth established by experts.

4. Adjudication method for the test set

Not applicable. There's no mention of a "test set" requiring adjudication in the context of this 510(k) submission.

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

Not applicable. This device is an electrosurgical tool, not an AI-powered diagnostic or assistive tool for human readers. No MRMC study was performed.

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

Not applicable. This device is not an algorithm; it's a physical surgical tool.

7. The type of ground truth used

The "ground truth" for this submission would be defined by engineering standards, functional specifications, and the performance characteristics of the predicate device, demonstrated through bench testing. It does not involve expert consensus, pathology, or outcomes data in the way an AI diagnostic device would.

8. The sample size for the training set

Not applicable. This device is not an AI algorithm; therefore, there is no "training set."

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

Not applicable. As there's no training set, there's no ground truth to establish for it in this context.

The provided 510(k) summary for the SurgRx EnSeal Vessel Sealing & Hemostasis System (K061526) states that preclinical laboratory (bench) and performance tests were executed to ensure the devices function as intended and meet design specifications. The submission then concludes that the system is equivalent to its predicate device based on these design validation results.

However, the summary does not provide specific details about the acceptance criteria or the study that "proves the device meets the acceptance criteria" in the format of the requested table and detailed analysis. This type of information is typically considered proprietary and is not fully disclosed in a public 510(k) summary. The summary focuses on establishing substantial equivalence to a predicate device (K031133) rather than presenting a detailed performance study with explicit acceptance criteria and results.

Therefore, I cannot fully complete the requested table and analysis due to the limited information available in the provided document.

Here's what can be inferred and what is missing:

Inferred Information from the 510(k) Summary

The summary indicates that "Preclinical laboratory (bench) and performance tests were executed to ensure the devices function as intended and meet design specifications." This implies that the device was evaluated for its ability to cut and seal vessels, grasp and dissect tissue effectively and safely, similar to its predicate device.

Missing Information - Cannot be Extracted from the Provided Document

1. Table of Acceptance Criteria and Reported Device Performance

Reason for missing information: The 510(k) summary did not disclose the specific quantifiable acceptance criteria or the detailed results of the performance tests. It broadly states that tests were done to "meet design specifications."

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

Reason for missing information: The document does not specify the sample size (e.g., number of vessels, tissues, or animals tested) used in the preclinical laboratory and performance tests. It also does not mention the country of origin of the data or whether it was retrospective or prospective.

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

Reason for missing information: The document does not mention the involvement of experts for establishing ground truth, as this type of preclinical testing typically involves engineers and researchers evaluating physical performance rather than clinical expert consensus.

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

Reason for missing information: This is not applicable to the preclinical bench and performance tests described. Adjudication methods are typically used in clinical studies involving human readers or evaluators.

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

Reason for missing information: This information is not relevant to the device described. The EnSeal system is an electrosurgical instrument, not an AI-powered diagnostic or assistive technology for human readers.

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

Reason for missing information: This is not applicable. The EnSeal system is a medical device requiring direct human operation, not a standalone algorithm.

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

Reason for missing information: For preclinical bench testing of an electrosurgical device, the "ground truth" would typically be established by objective measurements against engineering specifications and validated experimental methods (e.g., bursting pressure measurements for seals, microscopic analysis of tissue effects, temperature readings). The document does not specify these methods.

8. The sample size for the training set

Reason for missing information: Not applicable to this type of device. "Training set" is a concept used in machine learning and AI development, not for the validation of an electrosurgical instrument in the manner described. The device's design is based on engineering principles and previous predicate device experience, not a "training set" in the AI sense.

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

Reason for missing information: Not applicable for the same reason as point 8.

In summary, the provided 510(k) summary states that "Preclinical laboratory (bench) and performance tests were executed to ensure the devices function as intended and meet design specifications," leading to the conclusion of substantial equivalence. However, it explicitly lacks the granular detail regarding acceptance criteria, sample sizes, expert involvement, and specific performance results that would be needed to fulfill the request.

Ask a specific question about this device

The SurgRx EnSeal system includes bipolar electrosurgical instruments and an accessory adapter for use with standard electrosurgical generators. It is intended for use during open or laparoscopic general and gynecologic surgery to cut and seal vessels, cut, grasp and dissect tissue during surgery.

Indications for use include open and laparoscopic general and gynecological surgical procedures (including urologic, colorectal, urologic procedures, Nissen fundoplication, hysterectomies, oophorectomies, etc.), or any procedure where vessel ligation (cutting and sealing), tissue grasping and dissection in the same instrument can be used on tissue of any amount that will fit in the jaws of the instruments.

The SurgRx EnSeal Vessel Sealing & Hemostasis System has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this system for these procedures.

EnSeal™ Vessel Sealing and Hemostasis System. The functionality and components of the System are the same as the Predicate Device.

The provided text is a 510(k) summary for the SurgRx EnSeal Vessel Sealing & Hemostasis System. It states that the device is a modification of a previously cleared device (K031133) and does not require additional performance testing because the modification does not affect the system's performance. Therefore, typical acceptance criteria and a study demonstrating performance against those criteria, as one might find for a novel device, are not detailed in this document.

However, based on the information provided, we can deduce some aspects and limitations regarding "acceptance criteria" and "study."

Here's an analysis of the provided text in the context of your request:

1. Table of Acceptance Criteria and Reported Device Performance

This information is not explicitly provided in the document. The submission states: "This modification does not affect performance of the System. Additional performance testing not required." This implies that the device is expected to meet the same performance criteria as its predicate device (K031133), but those specific criteria are not listed here.

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

This information is not provided. As "additional performance testing not required," there would likely not have been a new test set for this 510(k) submission.

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

This information is not provided.

4. Adjudication Method for the Test Set

This information is not provided.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A MRMC study was not performed or mentioned in this document. The submission focuses on substantial equivalence based on the predicate device's performance, not comparative effectiveness with or without AI assistance.

6. Standalone Performance Study (Algorithm Only Without Human-in-the-Loop Performance)

This is not applicable as the device is an electrosurgical system, not an AI algorithm.

7. Type of Ground Truth Used

Not explicitly stated for this submission. For the original predicate device, performance would typically be evaluated against established biological, surgical, or engineering outcomes relevant to vessel sealing and hemostasis (e.g., burst pressure, thermal spread, tissue effect).

8. Sample Size for the Training Set

Not applicable as this is not an AI/ML device requiring a training set.

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

Not applicable.

Summary derived from the document:

The core "acceptance criterion" for this specific 510(k) submission (K050671) is substantial equivalence to the predicate device (K031133). The "study" that proves the device meets this "acceptance criterion" is the design validation that demonstrated the modification did not alter the existing system's performance.

From the text:

• Acceptance Criterion: Substantial equivalence to the predicate device (EnSeal™ Vessel Sealing and Hemostasis System # K031133), based on the functionality and components remaining the same. The implicit performance criteria are those established for the original predicate device.
• Study Proving Acceptance: "Results of design validation." The document explicitly states: "This modification does not affect performance of the System. Additional performance testing not required." This implies that the design validation assessed that the changes did not negatively impact the previously established performance of the predicate device.

The document is a 510(k) summary, which often focuses on demonstrating substantial equivalence to a predicate device rather than detailing extensive new performance studies if the changes are minor or do not impact core functionality.
