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:

| 21 CFR 878.5010
The Cypris eXact Suture (PP) is indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic and neurological procedures.
The Cypris eXact Suture (PTFE) is indicated for use in all types of soft tissue approximation and/or ligation, including dental and general surgeries.
The Cypris eXact Suture (PDO) is indicated for use in general soft tissue approximation and/or ligation, but not for use in cardiovascular or neurological tissues, microsurgery or ophthalmic surgery.
The Cypris eXact 5.1 Suture Placement Device can be used in conjunction with eXact Sutures, which are indicated for use in general soft tissue approximation and/or ligation.
The Cypris eXact Suturing System is comprised of the Cypris eXact Suture and the Cypris eXact 5.1 Suture Placement Device. The Cypris eXact Suture and the Cypris eXact 5.1 Suture Placement Device are for use in general soft tissue approximation by surgeons, are single-use, and are provided sterile.
The Cypris eXact Suture is a synthetic, monofilament suture available in three different materials: polypropylene (PP), polydioxanone (PDO), and polytetraflouroethylene (PTFE). The Cypris eXact Suture (PP) is a non-absorbable, sterile surgical suture available in two sizes, USP sizes 3-0 and 4-0. The Cypris eXact Suture (PTFE) is a non-absorbable, sterile surgical suture available in two sizes, USP sizes 2-0 and 3-0. The Cypris eXact Suture (PDO) is an absorbable, sterile surgical suture available in two sizes, USP sizes 3-0 and 4-0.

- Device Tested: Cypris eXact Sutures (PP, PTFE, PDO) and Cypris eXact 5.1 Suture Placement Device.
- Tests Performed:
- Suture Testing: Measurement of suture diameter, tensile strength, and needle attachment strength for various suture sizes and materials. These tests were conducted according to the specific methods outlined in the United States Pharmacopeia (USP) standards (, , ).
- Biocompatibility Testing: Evaluation of material interactions with biological systems, including cytotoxicity, sensitization, irritation (for the placement device), acute systemic toxicity, material-mediated pyrogenicity, subacute and subchronic toxicity, chronic toxicity, genotoxicity, carcinogenicity, and implantation (for the sutures). These tests followed ISO 10993-1:2018 guidelines.
- Shelf-life Testing: Evaluation of sterile barrier integrity and device functionality for the Cypris eXact 5.1 Suture Placement Device after 3 years of real-time aging to establish its shelf-life. The sutures had a separate, longer shelf-life of 5 years.
- Acceptance Criteria Basis: The acceptance criteria for each test were defined by the adherence to the requirements specified in the aforementioned USP standards, ISO 10993-1:2018, and FDA's specific guidance for surgical sutures.
- Conclusion: The tests demonstrated that the Cypris eXact Sutures meet all specified USP requirements and that all materials used are biocompatible. The Cypris eXact Sutures are explicitly stated as being "identical in their final finished form in formulation, processing, sterilization, and geometry to the sutures previously cleared" under the predicate devices (K131224, K160744, K063680). The Cypris eXact 5.1 Suture Placement Device also demonstrated integrity and functionality over its claimed shelf-life. This body of non-clinical evidence provided the basis for the FDA's determination of substantial equivalence.

2. Sample Size Used for the Test Set and Data Provenance
The document does not specify exact sample sizes for each non-clinical test. The testing was conducted to verify compliance with various established standards (USP, ISO, ASTM). The data provenance is generally "non-clinical tests" performed by the manufacturer in China (Huaian Seamen Medical Technology Co., LTD) to support the 510(k) submission. This is considered retrospective in the sense that the test results are being summarized for submission, not generated as part of a prospective clinical trial.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This is not a study involving diagnostic interpretation or machine learning where "ground truth" is established by experts in an interpretative capacity. The "ground truth" here is compliance with technical specifications and safety standards as measured by laboratory tests.
4. Adjudication Method for the Test Set
Not applicable. There is no adjudication method described as this is not a study involving human interpretation of data where disagreements need to be resolved. The test results are objective measurements against defined standards.
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 document is for a physical surgical device (sutures), not an AI/ML-driven diagnostic or interpretative device. Therefore, no MRMC study or AI assistance evaluation was performed or is relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is not an algorithm or AI device.
7. The Type of Ground Truth Used
The "ground truth" in this context refers to the defined acceptable parameters and thresholds within the cited standards (USP, ISO, ASTM). For example, the "ground truth" for suture diameter is the range specified in USP . For biocompatibility, the "ground truth" is the absence of adverse biological reactions as defined by ISO 10993 series. These are objective, measurable standards.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI/ML device that requires a training set or its associated ground truth establishment.

The Vesseal is intended for use in the delivery of 8 interrupted sutures to assist the surgeon in the creation of a vascular anastomosis in arteries of 2-4mm in diameter. It is not intended for use in coronary artery grafts.
The Vesseal is a hand-held device, enabling simultaneous deployment of 8 double-armed 9-0 to 7-0 nylon sutures (USP certified). The sutures are delivered from the inside out, around the circumference of two ends of blood vessels (ranging in size from 2mm to 4mm) to assist in the creation of a microvascular anastomosis. The Vesseal is comprised of two main mechanisms: 1. The needle insertion mechanism contains two rod protrusions, intended for locating the blood vessel, opening, mounting, and positioning them relative to the stopper mechanism. Each rod stores, 8 curved needles that allow the transition of the double-armed nylon sutures during deployment. 2. The handle deployment mechanism features right and left switches to deploy the needles on the respective rod side, and the gear to rotate the rod and enable access to its entire perimeter.
The given text is a 510(k) summary for the medical device "Vesseal". There is no mention of acceptance criteria or a study that proves the device meets acceptance criteria. The document describes the device, its intended use, comparison to predicate devices, and the types of performance data used to support substantial equivalence.
Therefore, I cannot provide an answer based on the provided text.

Trade/Device Name: DURAMESH™M Mesh Suture Regulation Number: 21 CFR 878.5010
Polypropylene |
| Regulation Number | 878.5010
Duramesh™ Mesh Suture is indicated for general soft tissue approximation and/or ligation in clean (CDC Class I) wounds, including tendon repair and midline laparotomy where the bowel is not entered. Duramesh™ is not for use in the skin and other epithelial surfaces, cardiovascular, ophthalmic, and/or neurological procedures.
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™.
Given this context, I cannot generate a response that directly addresses the prompt's specific requirements for AI/ML device acceptance criteria and study design, as the provided document is not about an AI/ML device.

Regulations: | 21 CFR 878.5000 (Nonabsorbable poly(ethylene terephthalate) surgical suture)
21 CFR 878.5010
The RAM® COR-SUTURE® QUICK LOAD® surgical suture is indicated for use in the approximation of soft tissue and prosthetic materials.
The COR-SUTURE® OUICK LOAD® surgical suture is indicated for use in the approximation of soft tissue and prosthetic materials.
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.

SUTURE, 2-0 Polyester RD QUCIK LOAD SUTURE, 2-0 Polypropylene Regulation Number: 21 CFR 878.5000 21 CFR 878.5010
| Nonabsorbable polypropylene surgical suture
(Regulation: 21 CFR 878.5010
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.
Acceptance Criteria (for Suture) | Reported Device Performance (Summary) |
---|---|
Conformance to USP 42-NF37:2019 Monograph for Non-Absorbable Sutures (Physical Tests) | The RD® QUICK LOAD® SUTURE continues to conform to these requirements and test methods. |
Biocompatibility in accordance with ISO 10993-1:2009(R)2013 | All appropriate biological endpoints for consideration per ISO 10993-1 were assessed with passing results. |
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.

| Classification
Regulation | 21 CFR 878.5010
| 21 CFR 878.5010
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.
