This document discusses the FDA clearance for the SafePath Suturing System, which includes silk, polyamide (nylon), and polypropylene sutures. However, the provided text does not contain information about a study based on AI/ML. All the performance criteria and testing mentioned relate to the physical and biological properties of the sutures and the suturing system, not to an AI component.

Therefore, I cannot answer your request with the specific details about acceptance criteria and studies related to AI/ML performance, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance.

The document highlights the following non-clinical performance criteria and testing for the sutures:

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

2. Sample size used for the test set and the data provenance: Not applicable as this is a non-AI/ML device. The testing was physical and biological, not based on data sets.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable as this is a non-AI/ML device. Ground truth as typically understood in AI/ML is not relevant here.

4. Adjudication method for the test set: Not applicable as this is a non-AI/ML device.

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 as this is a non-AI/ML device.

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

7. The type of ground truth used: For physical testing, ground truth would be established by the specifications of the USP standards. For biocompatibility, it's about meeting pre-defined safety thresholds as per recognized standards (e.g., ISO 10993).

8. The sample size for the training set: Not applicable as this is a non-AI/ML device.

9. How the ground truth for the training set was established: Not applicable as this is a non-AI/ML device.

The study described is a non-clinical performance testing study that evaluated the physical and biocompatibility characteristics of the sutures and the suturing system. The conclusions state that the device met or exceeded USP criteria for physical properties and met the test criteria for a battery of biocompatibility evaluations. The safety evaluation for the nylon and polypropylene sutures leveraged information from a previously cleared device (K180701) and used identical raw materials, packaging, and sterilization conditions as the predicate devices.

DURAMESH™ is a polyfilament, synthetic, non-absorbable, sterile surgical suture composed of isotactic polypropylene polymer of high molecular weight. The suture is provided dyed (blue) and is uniform in appearance. The blue dye pigment is Phthalocyaninato (2-) Copper. The product meets all requirements established by the United States Pharmacopeia (USP) for nonabsorbable surgical suture, except for diameter.

DURAMESH™ is passed on either side of tissues using an attached swaged needle as an introducing agent and tied to itself with at least two knots composed of two throws each to maintain tension.

DURAMESH™ is supplied sterile and is available with two needle configurations (small and large) in four USP sizes (2-0 through 2), each with a length of approximately 36 inches (91 cm). Each box contains one DURAMESH™ housed in a Tyvek envelope within which the DURAMESH™ is packaged in a sterile protective medical grade tube fixed to a sterile card.

The provided text does not describe an AI/ML medical device, but rather a surgical suture (DURAMESH™ Mesh Suture). Therefore, the concepts of acceptance criteria for AI/ML performance metrics (like sensitivity, specificity, AUC), sample size for test/training sets in an AI/ML context, number of experts for ground truth establishment, adjudication methods, MRMC studies, standalone performance, and ground truth types related to AI/ML are not applicable to this document.

The document focuses on demonstrating substantial equivalence of the DURAMESH™ Mesh Suture to a predicate device based on material, design, performance, and biological safety. The "acceptance criteria" here refer to the product's ability to meet medical device standards and show equivalence to a predicate, not AI/ML model performance metrics.

Specifically, the "Bench Data" section on page 6 mentions some performance criteria for the suture:

• Needle attachment strength: Meets prospectively defined acceptance criteria per USP43-NF38: 2020 Sutures - Needle Attachment.
• Tensile strength: Meets prospectively defined acceptance criteria per USP43-NF38: 2020 Sutures - Tensile Strength. It also meets USP requirements under simulated surgical deployment, cycle loading, and dynamic loading.
• Knot Size and Knot Strength: DURAMESH™ knots were stronger than predicate knots for the same number of throws. Knot security is achieved with 4 throws as per labeling.
• Diameter: Diameter decreases with increasing axial load.
• "Stripped" samples: Maintain adequate tensile strength to satisfy USP requirements.

The document also describes:

• Biocompatibility testing: Per ISO 10993-1, ISO 14971, and 2020 FDA Biocompatibility Guidance, showing biocompatibility based on various tests (cytotoxicity, sensitization, etc.).
• Packaging testing: According to ASTM D4169-16 and ASTM F1929-15.
• Sterilization: Ethylene Oxide sterilization following AAMI TIR28:2016 and ISO 11135:2014, meeting ISO 10993-7: 2008 limits for residuals.
• Shelf-Life: Accelerated and real-time aging stability testing supports a 5-year shelf life with no loss of tensile strength.
• Animal Data: Two large-animal porcine implantation studies (1- and 3-month) assessed adverse tissue reaction and dehiscence. Outcomes showed successful closure, tissue ingrowth, and slight irritation compared to standard polypropylene suture.
• Clinical Data: A single-investigator clinical trial with 53 patients (80 surgical sites).
  • Primary outcome: Surgical site occurrence (SSO). No early or late SSO observed.
  • Secondary outcomes: Device-related rehospitalization, return to OR, and wounds. No such events occurred.
  • Long-term assessment (12-month): 15 subjects compared to 11 patients with standard sutures, showing equivalent or slightly improved outcomes with DURAMESH™.

LSI SOLUTIONS® offers both the RAM® COR-SUTURE® QUICK LOAD® surgical suture, which is a non-absorbable polytetrafluoroethylene (PTFE)-coated, braided polyester surgical suture, and the COR-SUTURE® QUICK LOAD® surgical suture, which is available as either a PTFE-coated, braided polyester surgical suture or a monofilament, uncoated polypropylene surgical suture. The RAM® COR-SUTURE® QUICK LOAD® surgical suture is also supplied with an optional pre-attached PTFE pledget that is used to aid in suture buttressing and to mechanically secure and support the suture in fragile tissue, increasing the suture holding strength. A short length of modified surgical stainless-steel tubing, called a "needle cap", is attached to each end of the suture for both the RAM® COR-SUTURE® QUICK LOAD® surgical suture and the COR-SUTURE® QUICK LOAD® surgical suture. Relative to the COR-SUTURE® QUICK LOAD® device, the RAM® COR-SUTURE® QUICK LOAD® device additionally includes a needle cap holder to secure the optional pledget and needle caps in the suture tray. Both the RAM® COR-SUTURE® QUICK LOAD® surgical suture and the COR-SUTURE® QUICK LOAD® surgical suture also include a detachable clear suture tube to keep the suture from tangling. The needle caps are removed from the sutures and discarded once suturing is completed as they are not intended for implantation in the patient; only the suture and pledget are implantable of components.

Both devices are packaged for single patient use and are provided sterile by means of a validated ethylene oxide (EO) cycle. The polyester RAM® COR-SUTURE® QUICK LOAD® surgical suture is offered undyed (white), dyed green with the FDA approved colorant D&C Green No. 6. or striped green/white; all of which are offered with a surgical suture diameter of USP size 2-0 and a length of 38 inches. The polyester COR-SUTURE® QUICK LOAD® surgical suture is available undyed (white) or dyed green with the FDA approved colorant D&C Green No. 6 and will be offered with a surgical suture diameter of USP size 2-0 and a length of 38 inches. The polypropylene COR-SUTURE® QUICK LOAD® surgical suture is dyed blue with the FDA approved colorant [phthalocyaninato(2-)] copper and will be offered with a surgical suture diameter of USP size 3-0 and a length of 53 inches. For both polypropylene and polyester suture, there is no known significant change in tensile strength retention to occur in vivo. The RAM® COR-SUTURE® QUICK LOAD® and COR-SUTURE® QUICK LOAD® surgical sutures, with needle caps removed, contains implantable components which are considered MR safe. The implantable polyester and polypropylene sutures and PTFE pledget material are non-metallic and non-conducting materials and therefore, considered MR safe.

This document describes the RAM® COR-SUTURE® QUICK LOAD® and COR-SUTURE® QUICK LOAD® surgical sutures. It concerns a 510(k) premarket notification for these devices, asserting their substantial equivalence to a predicate device.

1. Table of acceptance criteria and the reported device performance:

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 does not explicitly state the sample size used for the benchtop testing test set. The data provenance is also not explicitly stated in terms of country of origin or whether it was retrospective or prospective. However, the testing was conducted as recommended by the FDA Guidance for Industry, Class II Special Control Guidance Document.

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 applicable. The device is a surgical suture, and "ground truth" as typically used in AI/medical imaging studies (e.g., expert consensus on diagnoses) is not relevant for this type of device and its performance testing. The performance is assessed against established physical standards and biocompatibility.

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

This information is not applicable. Adjudication methods are typically employed in studies involving human interpretation or subjective assessments, which is not the case for the physical and biocompatibility testing of a surgical suture.

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. This is a medical device (surgical suture) and not an AI-powered diagnostic or assistive tool for human readers.

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

This information is not applicable. This is a physical medical device, not an algorithm.

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

For the benchtop testing, the "ground truth" or standard for performance is the United States Pharmacopeia (USP), Monograph for Non-Absorbable Sutures, specifically sections from the USP General Chapter on Physical Tests.

For biocompatibility testing, the standards are ANSI AAMI ISO 10993-1:2009/(R)2013 Biological evaluation of medical devices Part 1: Evaluation and testing within a risk management process and the FDA Guidance for Industry, Use of International Standard ISO 10993-1.

8. The sample size for the training set:

This information is not applicable. There is no concept of a "training set" for physical and biocompatibility testing of a surgical suture.

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

This information is not applicable, as there is no training set for this type of device testing.

The RD® QUICK LOAD® suture is intended for use in general soft tissue approximation and/or ligation.

LSI SOLUTIONS® RD® QUICK LOAD® SUTURE is a non-absorbable surgical suture available as monofilament polypropylene suture (diameter of USP size 2-0) and polytetrafluoroethylene (PTFE)-coated, braided polyester suture (diameter of USP sizes 0 and 2-0). A short length of surgical stainless-steel tubing, called a "needle cap," is attached to one end of the suture. The needle cap is removed from the suture after suturing is completed and not meant for implantation into the patient. The RD® QUICK LOAD® SUTURE includes a detachable clear suture tube to keep the suture from tangling. The RD® QUICK LOAD® SUTURE is packaged for single patient use and is provided sterile by means of a validated ethylene oxide (EO) cycle. The polypropylene suture is dyed blue with the FDA approved colorant [phthalocyaninato(2-)] copper and will be offered with a surgical suture diameter of USP size 2-0 and in a length of 53 inches. The polyester suture is offered dyed green with the FDA approved colorant D&C Green No. 6 and is offered in a surgical suture diameter of USP size of 0 and 2-0 and a length of 53 inches. For both polypropylene and polyester suture, there is no known significant change in tensile strength retention to occur in vivo. The RD® QUICK LOAD® SUTURE products, with needle caps removed, contain implantable components which are considered MR (magnetic resonance) safe. The implantable polyester and polypropylene suture materials are non-metallic and nonconducting materials and therefore, considered MR safe.

This document does not describe a study involving an AI/Medical Device that requires the establishment of ground truth, expert consensus, or multi-reader multi-case studies. Instead, it is a 510(k) premarket notification for a surgical suture, the RD QUICK LOAD SUTURE, asserting its substantial equivalence to a previously cleared predicate device.

The acceptance criteria and proof of substantial equivalence for this suture device are based on non-clinical performance testing and biocompatibility assessment, not on clinical performance studies involving a test set, expert consensus, or multi-reader studies as one would expect for an AI/Medical Device.

Here's why and what information is provided:

1. Acceptance Criteria and Device Performance (for a Suture)

The acceptance criteria for the RD QUICK LOAD SUTURE are based on established standards for surgical sutures. The performance of the device is evaluated against these standards.

2. Sample Size and Data Provenance for Testing:

• Data provenance: The document states "Biocompatibility results from Teleflex® Medical OEM were leveraged." This implies testing was conducted by the raw material supplier.
• The specific sample sizes for the USP and biocompatibility testing are not explicitly stated in this document. These would typically be defined by the relevant standards and internal test protocols. The nature of this 510(k) summary means highly detailed test parameters are usually omitted, with the FDA reviewing the full test reports.
• The tests are non-clinical (benchtop and lab-based biocompatibility), not clinical.

3. Number of Experts/Qualifications (Not Applicable for Suture Evaluation):

This information is not relevant to the evaluation of a surgical suture's substantial equivalence based on physical and biocompatibility properties. There are no "experts" establishing ground truth in the context of image interpretation or diagnosis.

4. Adjudication Method (Not Applicable):

Not applicable for a medical device cleared through substantial equivalence based on physical and biological testing.

5. MRMC Comparative Effectiveness Study (Not Applicable):

• No MRMC study was done. This is a surgical suture, not a diagnostic AI device. There are no "human readers" to improve with AI assistance. Clinical studies were deemed unnecessary.

6. Standalone Performance (Not Applicable as AI):

This is not an AI/algorithm. Its performance is its tensile strength, knot security, and biocompatibility, which are tested through benchtop methods defined by USP standards.

7. Type of Ground Truth (for Suture Properties, not a Diagnostic):

• The "ground truth" for the suture's performance is established by validated physical test methods (USP standards) and biocompatibility testing against ISO standards.
• For the claim of substantial equivalence, the "ground truth" is also the performance of the predicate device, against which the new device is compared.

8. Sample Size for Training Set (Not Applicable - No AI/Machine Learning):

This device does not involve a "training set" in the context of AI or machine learning. It is a manufactured physical good.

9. How Ground Truth for Training Set was Established (Not Applicable):

Not applicable, as there's no training set for an AI model.

In summary, this FDA clearance document is for a traditional medical device (surgical suture) demonstrating chemical and physical equivalence to a predicate device, not an AI-powered diagnostic tool. Therefore, many of the requested criteria, which are standard for AI/ML device evaluations, are not applicable here.

The APTOS Threads - Polypropylene Surgical Sutures are indicated for general soft tissue approximation, excluding closure of the epidermis, where use of a non-absorbable suture is appropriate.

APTOS Threads - Polypropylene Surgical Sutures are a dyed, nonabsorbable, sterile surgical strand of polypropylene in USP size 2-0. The base product is an isotactic crystalline stereoisomer of polypropylene, a synthetic linear polyolefin. The pigmented suture is dyed blue (with [Phthalocyaninato(2-)] copper, Color Index Number 74160) to enhance visibility; the colorant meets all requirements of US 21CFR, Parts 70-82. There is no coating or any other additives. The threads incorporate a bidirectional barbed design. The threads are supplied with needles attached to both ends. The thread's upper and lower anchoring sections are barbed in opposite direction with a small unbarbed section between them and two smooth unbarbed sections, each immediately adjacent to needle-thread attachment interfaces. The needles are constructed from 420B stainless steel. The needles are provided sterile via Ethylene Oxide sterilization.

This document describes the premarket notification for APTOS Threads - Polypropylene Surgical Sutures. As a medical device, the acceptance criteria and supporting studies focus on demonstrating its substantial equivalence to a legally marketed predicate device (FilBloc Permanent Sutures, K171039) rather than on specific diagnostic performance metrics of an AI algorithm.

Therefore, the requested information on AI-specific criteria, sample sizes for test/training sets for AI, expert adjudication, MRMC studies, or standalone algorithm performance are not applicable in this context.

The acceptance criteria for this device are based on its physical properties, biocompatibility, and sterility, ensuring it functions similarly and as safely as existing sutures.

This information is not applicable as the document describes a 510(k) submission for a non-AI surgical suture, which does not involve "test sets" in the context of AI performance evaluation. The "testing" refers to laboratory and ex-vivo studies on the material and mechanical properties of the suture.

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 applicable as the document describes a 510(k) submission for a non-AI surgical suture. Ground truth in this context is established through standardized laboratory testing protocols, not expert consensus on diagnostic interpretations.

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

This information is not applicable as the document describes a 510(k) submission for a non-AI surgical suture. Adjudication methods are relevant for subjective interpretations, which are not part of the physical and biological testing of a suture.

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 as the document describes a 510(k) submission for a non-AI surgical suture. This type of study relates to AI-assisted diagnostic tools and human reader performance, not physical medical devices like sutures.

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

This information is not applicable as the device is a physical surgical suture, not an AI algorithm.

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

The "ground truth" for this device, in essence, is established through:

• Standardized Material Specifications: Polypropylene material and dye complying with US 21CFR, Parts 70-82.
• USP Standards: Compliance with United States Pharmacopeia (USP) standards ( suture diameter, suture attachment, tensile strength).
• ISO Standards: Compliance with ISO 10993 series for biocompatibility and ISO 11135 for sterilization.
• ASTM Standards: Compliance with relevant ASTM standards for hemocompatibility (F756-17) and shelf life testing (D4169-16, F88/F88M-15, F2096-11).
• Ex-vivo Comparative Performance: Direct comparison of tissue holding strength to a legally marketed predicate device.

These standards and comparative studies serve as the "ground truth" to demonstrate that the device is safe and effective for its intended use and substantially equivalent to predicate devices.
