StitchKit® Suture Delivery Canister facilitates minimally invasive robotic surgery by transporting suture to the operative field and removing used needles after suturing. The suture contained within the device is intended for soft tissue approximation where use of the specific absorbable or non-absorbable sutures contained within it is appropriate.

StitchKit® is a sterile, single-use plastic canister that is provided pre-loaded with suturing materials with attached needles. The device facilitates endoscopic robotic surgery by introducing multiple strands of suture to the surgical site at one time and allowing for the safe retrieval of the needles. The canister is sized to be passed through a ≥12 mm trocar or passed through an incision sized for an 8 mm trocar under direct endoscopic visualization. As suturing is completed with each strand, the used needle is placed into a compartment within the canister for safekeeping until the entire canister is removed either through the ≥ 12 mm trocar or through the 8mm trocar incision in tandem with the 8mm trocar, also under direct endoscopic visualization using the attached retrieval string. It is supplied sterile.

The provided text describes a 510(k) premarket notification for a medical device called StitchKit®. This document primarily focuses on demonstrating substantial equivalence to a predicate device, specifically for a minor modification related to the device's insertion and removal method (allowing use through an 8mm trocar incision in addition to a 12mm trocar).

Crucially, this document does NOT describe the acceptance criteria or a study proving the device meets performance criteria for a complex AI/ML medical device. The device in question is a suture delivery canister, a physical surgical tool, not an AI or imaging device. Therefore, many of the requested points related to AI/ML device validation (like expert adjudication, MRMC studies, ground truth for training/test sets, effect size of human reader improvement with AI assistance, and standalone AI performance) are not applicable to this submission.

The "clinical data" mentioned (retrospective case review n=422) is cited in the context of supporting the modification to the instructions for use, not for establishing the core performance of an AI algorithm. The performance data section refers to "functional performance test consisting of simulated surgical testing in an animal model" to demonstrate compatibility with the new insertion/removal technique, which is a physical device test, not an AI/ML study.

Therefore, I cannot fulfill most of your request for an AI/ML device, as the provided document pertains to a physical surgical device and its minor instruction for use modification.

However, I can extract the safety and efficacy information relevant to this device (the StitchKit® suture delivery canister) as presented in the document, acknowledging that it doesn't align with the detailed AI/ML validation questions.

Based on the provided document for the StitchKit® Suture Delivery Canister (a non-AI device):

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

The document does not specify formal, quantitative acceptance criteria for device performance in the typical sense of accuracy, sensitivity, or specificity, as it's a physical tool. Instead, the "performance" demonstrated relates to its functional compatibility with a new surgical technique.

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

• Test Set (for the modification validity):
  • Sample Size: n=422 (Cited as a "retrospective case review clinical study").
  • Data Provenance: Conducted by "an academic medical center." The country of origin is not specified but is implicitly in the US due to FDA submission. The study was retrospective.
• Functional Performance Test: Conducted in an "animal model." Sample size for this specific test is not provided.

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

• Not Applicable. This is a physical device, not an AI/ML diagnostic or image analysis device where "ground truth" would be established by experts interpreting medical data. The "ground truth" for the retrospective case review would likely be the surgical outcomes or successful use reported in the patient records.

4. Adjudication method for the test set

• Not Applicable. As above, no expert adjudication process is described or relevant for this type of device and study.

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. No MRMC study was done, as this is not an AI-assisted diagnostic device.

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

• Not Applicable. No standalone algorithm performance was evaluated, as this is not an algorithm-based device.

7. The type of ground truth used

• For the retrospective case review (n=422), the "ground truth" would be derived from clinical records and surgical outcomes related to the use of the device in actual patient cases, rather than expert interpretation of images or pathology. The document doesn't explicitly state how "success" or "performance" was quantified from these cases, but it supports the safety/effectiveness of the device, particularly with the proposed instruction modification.
• For the animal model functional test, the "ground truth" was direct observation of the device's physical handling and compatibility with the 8mm trocar site.

8. The sample size for the training set

• Not Applicable. There is no "training set" as this is not an machine learning model.

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

• Not Applicable. No training set was used.

This document describes a 510(k) premarket notification for a medical device, specifically a surgical suture. It does not contain information about an AI/ML medical device, which would typically include acceptance criteria, study details (sample size, data provenance, ground truth establishment, expert qualifications, etc.), or details of human reader studies (MRMC).

Therefore, I cannot provide the requested information regarding acceptance criteria and the study that proves the device meets them, as the provided text pertains to a traditional medical device (surgical suture) and not an AI/ML device. The document focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance testing rather than the detailed clinical validation studies common for AI/ML products.

MONOFIX PGCL, knotless wound closure device is indicated for use in soft tissue approximation where the use of absorbable suture is appropriate. MONOFIX PGCL, knotless wound closure device should not be used to approximate tissue under tension and the use of barbed suture has not been shown to be safe in the closure of hernias, laparotomy incisions, bowel anastomosis or suture lines, vascular suture lines, and vaginal cuff closure in controlled clinical or preclinical studies for minimally invasive or open surgery.

MONOFIX PGCL, knotless wound closure device, comprised of Poly(glycolide-co-carprolactone)(PGA-PCL) is a synthetic absorbable monofilament undyed-suture. It is available sterile, developed by Samyang Holdings Corp., Ltd. The MONOFIX PGCL, knotless wound closure device consists of a Barb-type suture and a surgical needle, with a suture at one end and a stopper shaped end for tissue anchoring at the stopper is attached to the end of the suture and has a triangular shape with one side length of 1.8 to 3.3 mm and a thickness of 0.7 to 1.0 mm. The device is designed with small uni-directional barbs in size 0.18-0.55 mm along the length and stopper that eliminate the need to tie knots during approximation. The device is available in lengths of 15 to 60cm and diameter sizes 1 through 3-0 with needles in 1/2 circle, 5/8 circle, 1/2 curved and straight shapes attached to each end.

This appears to be an FDA 510(k) clearance letter and a summary of the predicate device comparison for a surgical suture, not a diagnostic AI/ML device. Therefore, the requested information regarding acceptance criteria, study details (sample size, data provenance, expert consensus, MRMC studies, standalone performance), and ground truth establishment, which are typical for AI/ML device submissions, are not applicable in this context.

The document describes the non-clinical tests performed to demonstrate the device's compliance with established standards for surgical sutures. These include:

• Bench tests: To verify design specifications, focusing on:
  • USP Suture Diameter
  • USP Suture-Needle attachment
  • USP Tensile Strength Surgical Suture
  • USP Monographs: Absorbable Surgical Suture
  • EP Monographs: Sutures, Sterile Synthetic Absorbable Monofilament
• Sterilization validation: ISO 11135:2014, ISO 10993-7
• Sterile barrier system testing: ASTM F 88
• Accelerated aging stability testing: ASTM F 1980
• Biocompatibility testing: A comprehensive suite of ISO 10993 standards (e.g., ISO 10993-5, -10, -11, -4, -12, -3, -6) and ASTM F756-17.
• In vivo tensile strength: Performed to evaluate tensile strength retention rate.

The "Acceptance Criteria" in this document would refer to the specific thresholds and performance requirements defined by these standards (e.g., minimum tensile strength, maximum/minimum diameter, acceptable levels of residuals, successful sterilization). The "Reported Device Performance" would be the results from the tests confirming the device met these criteria.

Therefore, it is impossible to provide the table and study details as requested because this document does not pertain to an AI/ML device. The study outlined is a non-clinical, benchtop and biocompatibility assessment, not a clinical performance study with human readers or AI algorithms.

StitchKit® is a suture delivery canister which facilitates endoscopic robotic surgery by introducing multiple strands of different suturing materials to the surgical site at one time and allowing for the safe retrieval of the needles. It is sized to be passed through a ≥12 mm trocar. As suturing is completed with each strand, the used needle is placed into a disposal compartment within the canister for safekeeping until the entire canister is removed through the trocar using the attached retrieval string. It is supplied sterile. Each StitchKit® contains strands of existing legally-marketed Suturing Materials, cleared for use within the device.

The provided document is a 510(k) summary for the StitchKit® Suture Delivery Canister, which is a Class II medical device. This document details the device's indications for use, technological characteristics, and substantiates its substantial equivalence to predicate devices, rather than presenting a study to prove acceptance criteria in the typical sense of a human-in-the-loop AI effectiveness study.

The device itself is a delivery system for existing sutures and not an AI-powered diagnostic or assistive device. Therefore, many of the requested criteria related to AI performance, AI effect size on human readers, expert ground truth, and training data are not applicable to this submission.

Here's an analysis of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

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

The document does not specify a "test set" in the context of an AI study. Instead, it refers to various forms of performance testing on the device and its components. The document doesn't provide specific sample sizes for these tests (e.g., number of sutures tested for tensile strength or number of canisters tested for pyrogenicity). The provenance of the data (e.g., country of origin, retrospective/prospective) is also not specified, as this type of information is typically not included in a 510(k) summary for a physical device.

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

Not applicable. As this is not an AI or diagnostic device, there is no "ground truth" established by experts in the context of image interpretation or clinical diagnosis. The performance criteria are based on objective physical/chemical tests.

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

Not applicable. As there are no expert interpretations or subjective assessments requiring adjudication, no such method was used.

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. The StitchKit® is a physical surgical delivery device and does not involve AI or human readers for diagnostic assistance. Therefore, an MRMC study and AI effect size are irrelevant.

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

Not applicable. This device does not involve an algorithm.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

StitchKit® Suture Delivery Canister facilitates minimally invasive robotic surgery by transporting suture to the operative field and removing used needles after suturing. The suture contained within the StitchKit® device is intended for soft tissue approximation where use of the specific absorbable or non-absorbable sutures contained within it is appropriate.

StitchKit® COMBO is a suture delivery canister which facilitates endoscopic robotic surgery by introducing multiple strands of different suturing materials to the surgical site at one time and allowing for the safe retrieval of the needles. It is sized to be passed through a ≥12 mm trocar. As suturing is completed with each strand, the used needle is placed into a disposal compartment within the canister for safekeeping until the entire canister is removed through the trocar using the attached retrieval string. It is supplied sterile in a foil pouch. Each StitchKit® version contains strands of existing legallymarketed Suturing Materials, cleared for use within the StitchKit®.

This looks like a 510(k) summary for a medical device called "StitchKit® COMBO Suture Delivery Canister". Based on the provided text, the device is explicitly a suture delivery system and not an AI or imaging device, so the requested information about AI performance, ground truth, expert adjudication, etc., is not applicable.

• No AI component: The document describes a "suture delivery canister which facilitates minimally invasive robotic surgery by transporting suture to the operative field and removing used needles after suturing." There is no mention of artificial intelligence, machine learning, image analysis, or any diagnostic capabilities.
• Physical device, not a diagnostic algorithm: The device handles physical sutures and needles. The performance data listed (knot-pull tensile testing, diameter, needle attachment, biodegradation testing, pyrogen testing, physico-chemical analysis, stability evaluations) are all related to the physical properties and safety of the surgical sutures and the delivery system itself, not to the performance of a software algorithm.

Therefore, since the device is not an AI/ML medical device, the following points from your request are not applicable and cannot be found in the provided text:

1. A table of acceptance criteria and the reported device performance (The "performance data" mentioned refers to physical product testing, not AI performance metrics)
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
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)
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
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
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
8. The sample size for the training set
9. How the ground truth for the training set was established

MONOCRYL™ Plus Antibacterial Suture is available undyed and dyed with D&C Violet No. 2

MONOCRYL™ Plus Antibacterial Suture contains Irgacare®† MP (triclosan), a broad spectrum antibacterial agent, at no more than 2360 µg/m.

This document is a 510(k) premarket notification for a medical device called MONOCRYL™ Plus Antibacterial Suture. It seeks to demonstrate substantial equivalence to a previously cleared device. Therefore, the information provided focuses on the equivalence of the modified device to its predicate, rather than detailing a de novo study to establish acceptance criteria and prove performance against them as would be typical for a novel device or AI/software.

Based on the provided text, here's an analysis of the "acceptance criteria" and "study" as they relate to this specific 510(k) submission:

Understanding the Context:

This submission (K201996) is for a modified device (MONOCRYL™ Plus Antibacterial Suture) that is largely identical to a predicate device (MONOCRYL™ Plus Antibacterial Poliglecaprone – 25 with 510(k) number K050845). The only reported changes are to the labeling, specifically updating in vitro effectiveness against an additional microorganism and including new descriptors/icons.

For a 510(k) involving minor changes, the "acceptance criteria" revolve around demonstrating that the modified device remains as safe and effective as the predicate, or that the changes do not raise new questions of safety or effectiveness. The "study" in this context refers to the data presented to support this claim, rather than a clinical trial for a new product.

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

Since this is a submission for a modified device essentially claiming no change in technological characteristics, the "acceptance criteria" are implicitly that the modified device retains the performance attributes of the predicate. The "reported device performance" is essentially a reaffirmation of the predicate's performance, along with specific in vitro data for the antibacterial claims.

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

The document mentions "in vitro efficacy studies" for the antibacterial claims. Details on the specific sample sizes (e.g., number of suture samples, number of bacterial cultures) are not provided in this summary. The data provenance is described as "in vitro," implying laboratory studies, rather than patient data. No information on country of origin or retrospective/prospective nature is given, as it's not a clinical study.

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

This type of information is generally relevant for AI/radiology devices where expert consensus is used to label images. For a physical medical device like a suture, "ground truth" for material properties and antibacterial efficacy is established through standardized laboratory testing and validated analytical methods (e.g., chemical analysis, microbiology assays). The document does not specify the number or qualifications of experts involved in running these in vitro tests, as this is typically handled by qualified laboratory personnel following established protocols.

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

Not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical studies, particularly for imaging interpretation, to resolve discrepancies between readers. This document describes laboratory in vitro studies for which such an adjudication method is not relevant.

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 a physical surgical suture, not an AI or imaging diagnostic tool. Therefore, MRMC studies and human reader improvement with AI assistance are not relevant.

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

Not applicable. This document is about a physical medical device, not an algorithm or AI.

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

For the antibacterial claims, the "ground truth" would be established by the results of the microbiological in vitro assays which directly measure the inhibition of bacterial colonization on the suture material. For the material properties, the "ground truth" is established by chemical and physical testing against established standards (e.g., USP monographs). This is empirical data from laboratory studies, not consensus of human experts on subjective interpretations.

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device that requires training data.

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

Not applicable, as explained in point 8.
