Demetech Absorbable Surgical Gut Suture (Plain and Chromic) is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular and neurological procedures".

Demetech Surgical gut suture (Plain and Chromic) is an absorbable sterile surgical suture composed of purified connective tissue (mostly collagen) derived from either the serosal layer of beef (bovine) or the submucosal fibrous layer of sheep (ovine) intestines.

The provided document is a 510(k) summary for the Demetech Absorbable Surgical Gut Suture (Plain and Chromic), demonstrating substantial equivalence to predicate devices, rather than an AI/ML device study. Therefore, most of the requested information regarding acceptance criteria, study types (MRMC, standalone), expert involvement, and ground truth establishment is not applicable in this context.

However, I can extract the relevant information from the document to address the aspects that are present:

1. Table of Acceptance Criteria and Reported Device Performance:

The "acceptance criteria" here refers to meeting the performance requirements defined by the United States Pharmacopeia (USP) for absorbable surgical sutures, specifically USP 23 and the current edition USP 24. The reported device performance is that Demetech's suture "meets or exceeds" these requirements.

2. Sample size used for the test set and the data provenance: Not applicable. This is not a study involving a "test set" of data in the context of AI/ML. The performance testing is likely conducted on batches of manufactured sutures. The document does not specify sample sizes or data provenance (country of origin, retrospective/prospective) for these tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for suture performance is established by standardized physical tests, not expert consensus.

4. Adjudication method for the test set: Not applicable.

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 is not an AI/ML device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI/ML device.

7. The type of ground truth used:
The ground truth used for evaluating the Demetech suture is standardized physical tests against the requirements of the United States Pharmacopeia (USP 23 and USP 24). This includes:

• General performance requirements for "Absorbable Surgical Suture"
• Specific requirements for "Diameter" ()
• Specific requirements for "Tensile Strength" ()
• Specific requirements for "Needle Attachment" ()
• Specific requirements for "Finish suture Length Requirement" (95% of stated label length)

8. The sample size for the training set: Not applicable. This is not an AI/ML device, so there is no concept of a "training set."

9. How the ground truth for the training set was established: Not applicable.

The SuturTek FASTCLOSE Suturing Device is intended for soft tissue approximation and/or ligation in general surgical procedures.

The use of this device with absorbable sutures is not indicated for use in cardiovascular and neurological procedures.

It is designed to aid in the prevention of suture needle stick injuries.

The FASTCLOSE Device has four major components: 1) a reusable instrument, 2) a single-use, disposable cartridge, 3) a single-use, disposable needle, and 4) sutures.

The cartridge containing the needle (with suture attached) is loaded onto the distal end of the device. The needle is engaged by the device's internal drive mechanism and driven through the tissue to be sutured. The suture is thus passed completely through the wound. Once the suture is in place, the device is withdrawn from the incision leaving the suture strand looped through the tissue. The two ends of the suture are then tied together in the usual manner.

The provided text describes a 510(k) premarket notification for the SuturTek FASTCLOSE™ Suturing Device. The submission focuses on demonstrating substantial equivalence to a previously marketed device (K011105) and highlights an added "Sharps Injury Prevention Feature Claims."

However, the document does not contain the detailed information required to fulfill your request regarding acceptance criteria and a study proving the device meets those criteria, particularly for an AI/ML device. The provided text describes a medical device (suturing device) and its premarket notification, which is a different type of submission than what would typically include AI/ML performance data.

Here's a breakdown of why the requested information cannot be extracted from the given text:

1. AI/ML Device: The SuturTek FASTCLOSE™ Suturing Device is a manual instrument, not an AI/ML powered device. Therefore, the concepts of "test set," "training set," "ground truth," "experts," "adjudication," "MRMC comparative effectiveness study," or "standalone algorithm performance" as they relate to AI/ML devices are not applicable or discussed in this document.

2. Acceptance Criteria and Device Performance: The document states that "Tests applicable to the type of safety device and safety features of the FASTCLOSE Device per the FDA Guidance on the Content of Premarket Notification Submissions for Medical Devices with Sharps Injury Prevention Features' (March 1995) were: Simulated Use Testing." However, it does not provide:

   • Specific quantitative acceptance criteria (e.g., "sharps injury reduction rate of X%").
   • The reported device performance against those criteria (e.g., "achieved Y% reduction").
   • Any details about the methodology, sample size, or results of the "Simulated Use Testing."

3. Ground Truth, Experts, Adjudication: These terms are relevant for evaluating diagnostic or predictive AI/ML models where there's a need to establish a definitive correct answer (ground truth) often through expert consensus. For a mechanical surgical device with a sharps injury prevention feature, the "ground truth" would likely be the actual occurrence or non-occurrence of a sharps injury during simulated use, and typically wouldn't involve expert adjudication in the same way an image interpretation task would. No such details are present.

In summary, the provided document is a 510(k) summary for a mechanical surgical device and does not contain the specific information you've requested regarding acceptance criteria and performance studies in the context of an AI/ML device.

To illustrate, if this were an AI/ML device, the detailed information about acceptance criteria and study results would typically be found in a "Performance Testing" section that provides quantitative metrics (e.g., sensitivity, specificity, AUC) and a thorough description of the study design. This document does not include such a section.

Grams Absorbable Surgical Gut Suture (Plain and Chromic) is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular and neurological procedures.

Grams Surgical gut suture (Plain and Chromic) is an absorbable sterile surgical suture composed of purified connective tissue (mostly collagen) derived from either the serosal layer of beef (bovine) or the submucosal fibrous layer of sheep (ovine) intestines.

Here's an analysis of the provided text regarding the acceptance criteria and study for the Grams Absorbable Surgical Gut Suture (Plain and Chromic):

This document describes a 510(k) premarket notification for a medical device (surgical suture), not an AI/ML device. Therefore, many of the requested categories related to AI/ML specific studies (like sample size for test/training sets, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance) are not applicable. The device's "performance" is based on conformity to established physical and chemical standards for surgical sutures.

Acceptance Criteria and Reported Device Performance

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size for Test Set: Not explicitly stated. The document refers to "performance testing data" but does not give specific numbers of sutures tested.
• Data Provenance: Not specified, but implied to be from a manufacturing and testing process adhering to USP standards. Given the applicant's address (Grafton, Wisconsin, USA), it's highly likely the testing was conducted in the USA or by a facility adhering to US regulations. The testing methodology would be prospective based on current manufacturing batches.

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

• Number of Experts: Not applicable. The "ground truth" for suture performance is established by objective, standardized physical and chemical tests defined in the United States Pharmacopeia (USP Monograph). This does not involve expert consensus in the way an AI diagnostic tool would.
• Qualifications of Experts: Not applicable for establishing ground truth; however, the testing would be performed by qualified laboratory personnel following USP protocols.

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

• Adjudication Method: Not applicable. The performance is based on objective measurements against USP standards, not subjective assessment requiring 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

• MRMC Study: No. This is a traditional medical device (suture), not an AI/ML device.

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

• Standalone Study: Not applicable. This is not an algorithm or AI device. The "standalone" performance here would refer to the physical and chemical characteristics of the suture itself.

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

• Type of Ground Truth: The ground truth is defined by objective, standardized measurements against the specifications and test methods outlined in the United States Pharmacopeia (USP 23 and USP 24) for "Absorbable Surgical Suture", "Diameter" , "Tensile Strength" , "Needle Attachment" , and "Finish suture Length Requirement".

8. The sample size for the training set

• Sample Size for Training Set: Not applicable. This is not an AI/ML device. The "training" for a physical device is its manufacturing process and quality control, which is implicitly ongoing.

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

• How Ground Truth for Training Set was Established: Not applicable. For a manufactured product like a suture, ongoing quality control and adherence to manufacturing specifications ensure consistency. The "ground truth" for the manufacturing process is its ability to consistently produce sutures that meet the USP standards, which are verified through the performance testing mentioned in the document.
