2. Sample Sizes Used for the Test Set and Data Provenance
-
Biocompatibility Testing: The document does not specify the sample sizes (number of devices or biological samples) used for each biocompatibility test.
-
Product Testing: The document does not specify the sample sizes for the product tests (Actuation Torque, Fastener Deployment, Fastener Gap Height, Ball Burst Testing, Mesh Compatibility, Resorption Profile).
-
Animal Study: The document does not specify the number of animals used in the study.
-
Data Provenance: The studies are described as "preclinical testing" and were conducted to support the 510(k) submission, implying they were prospective studies. The country of origin of the data is not specified, but the submission is to the U.S. FDA by a company based in Warwick, Rhode Island, USA.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
- Biocompatibility Testing: Ground truth is established by standardized biological evaluation methods (ISO 10993-1). No specific "experts" for ground truth are mentioned beyond the execution of these standardized tests.
- Product Testing: Ground truth is based on engineering specifications and benchmark performance against the predicate device. No specific "experts" (e.g., engineers with a certain number of years of experience) for ground truth establishment are detailed within the narrative.
- Animal Study: The evaluation included "histological evaluation of the tissue". This would typically involve pathologists, but the number and qualifications of these experts are not provided.
4. Adjudication Method for the Test Set
Not applicable. The tests described are primarily objective, quantitative measurements (e.g., torque, force, gap height, material degradation, histological analysis in the animal study). There is no mention of a human-centric "test set" requiring adjudication or consensus for classification.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. The document explicitly states: "Clinical studies were not performed for the submission of this proposed device nor were clinical studies performed for the primary predicate device (OptiFix-K142873)." Therefore, no MRMC study, or any clinical study involving human readers, was conducted.

The OptiFix" Open Absorbable Fixation System, hereinafter referred to as "OptiFix" Open", is a sterile (via gamma) single use device that is comprised of a deployment component and an absorbable fastener component. The device delivers 20 synthetic absorbable fasteners via a curved shaft. The shaft of the OptiFix™ Open Absorbable Fixation System is 27cm in length. The fasteners are 6.7mm in length, are manufactured from Poly (D, L)-lactide and are dyed with D & C Violet No. 2.
The provided document does not describe the acceptance criteria of an AI device, but rather a medical device (OptiFix™ Open Absorbable Fixation System). It outlines the performance data required to demonstrate substantial equivalence to a predicate device for this non-AI medical device. Therefore, I cannot generate the requested information about acceptance criteria and studies for an AI device based on this input.
The document discusses various tests for the OptiFix™ Open Absorbable Fixation System, including:
- Biocompatibility testing: This evaluated the absorbable fasteners (long-term implants) and the deployment component (transient tissue contact) against ISO 10993-1. All samples met acceptance criteria.
- Product Testing: This included performance and functional testing (Actuation (trigger) Torque, Fastener Deployment, Fastener Gap Height, Ball Burst Testing, Single Fastener Pullout (Pluck) Force) and Resorption Profile Assessment (Physical Properties, Mechanical Shear Force). All samples met established acceptance criteria.
The document states that animal studies and clinical studies were not performed for the proposed device, nor for the predicate device. The in vivo performance was supported by studies on previously cleared reference devices. Electrical safety, electromagnetic compatibility, and software verification/validation were not applicable as the device is not electro-mechanical and does not contain software.

Phasix™ Mesh is indicated to reinforce soft tissue where weakness exists in patients undergoing plastic and reconstructive surgery, or for use in procedures involving soft tissue repair of hernia or other fascial defects that require the addition of a reinforcing or bridging material to obtain the desired surgical result.
The proposed Phasix™ Mesh utilizes a fully resorbable poly-4-hydroxybutyrate (P4HB) polymer material. The P4HB is produced from a naturally occurring monomer, processed into monofilament fiber, and then knitted into a surgical mesh. Phasix™ Mesh is packaged individually as a sterile, single, flat mesh available in a wide range of shapes and sizes. Phasix™ Mesh provides immediate short-term support, and a scaffold that enables tissue in-growth over time while the mesh predictably and gradually degrades via hydrolysis and a hydrolytic enzymatic digestive process. Preclinical implantation studies indicate that Phasix™ Mesh retains approximately 70% of its strength at 12 weeks. Absorption of the mesh material is essentially complete within 12 to 18 months.
The provided document is a 510(k) Premarket Notification for a medical device called Phasix™ Mesh. This document focuses on demonstrating substantial equivalence to a previously cleared predicate device, rather than providing detailed acceptance criteria and a study to prove a device meets those criteria from scratch.
Therefore, the information requested in your prompt regarding acceptance criteria, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, training data, etc., is not available within this type of regulatory submission. This document highlights that the proposed device is so similar to an already approved device that extensive new studies are not required.
Here's how to interpret the document in the context of your request:
1. A table of acceptance criteria and the reported device performance
- Acceptance Criteria: The "acceptance criteria" here are implicitly that the proposed Phasix™ Mesh performs similarly or equivalently to the predicate Phasix™ Mesh (K142818) across various physical and biological characteristics. The FDA's substantial equivalence determination means they accepted that the proposed device is just as safe and effective as the predicate.
- Reported Device Performance: The document states that "The proposed Phasix™ Mesh demonstrated equivalent performance in comparison to the predicate device" for the following non-clinical tests:
- Mesh thickness
- Mesh knit construction
- Mesh pore size
- Mesh density
- Tensile strength
- Device stiffness
- Suture pullout strength
- Burst strength
- Tear resistance
- Specific performance values are NOT provided. The document only states "equivalent performance," implying that the results fell within acceptable ranges or were statistically comparable to the predicate.
2. Sample size used for the test set and the data provenance
- Test Set (Bench Testing): The specific sample sizes for the bench tests listed above are not reported in this summary.
- Data Provenance: The bench testing was conducted by the manufacturer, C.R. Bard, Inc. (Davol Inc. is the submitter). The country of origin for the data is not specified but would typically be the location of the manufacturing and testing facilities. These appear to be retrospective tests designed to compare the proposed device to the predicate.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not applicable. For this type of physical/mechanical performance testing, "ground truth" is established through standardized engineering and materials science methods, not expert consensus in the clinical sense.
4. Adjudication method for the test set
- Not applicable. Adjudication is typically for clinical or interpretative tasks, not for objective physical measurements.
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
- No MRMC study was done. This device is a surgical mesh, not an AI-powered diagnostic or assistive technology.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This device is a surgical mesh, not an algorithm.
7. The type of ground truth used
- For the bench tests, the "ground truth" is the objective measurement (e.g., actual mesh thickness, measured tensile strength) derived from standardized test methods.
- For biocompatibility and in-vivo studies, the "ground truth" is established through the results of standardized biological and animal tests. In this case, previous studies for the predicate device (K142818) were adopted because the proposed device uses the same materials and knit characteristics. These previous studies would have established biocompatibility based on ISO 10993-1 and characterized mechanical strength and resorption profiles in animal models.
8. The sample size for the training set
- Not applicable. This is not a machine learning or AI device that would require a "training set."
9. How the ground truth for the training set was established
- Not applicable.
In summary: This document is a regulatory submission for a device seeking substantial equivalence to a predicate. It relies heavily on the fact that the proposed device uses almost identical technology and materials as an already-approved device, therefore adopting prior testing results rather than generating entirely new, extensive clinical or comparative effectiveness data. The "acceptance criteria" are effectively that the new device's physical and biological properties are equivalent to the predicate, as demonstrated through bench testing and by leveraging prior biocompatibility and animal study data.

The CapSure ™ Permanent Fixation System is indicated for the approximation of soft tissue and fixation of surgical mesh to tissues during open or laparoscopic surgical procedures, such as hernia repair.
The CapSure™ Permanent Fixation System is a sterile single use device that delivers either 15 or 30 permanent fasteners via a straight shaft. The shaft of the CapSure™ Permanent Fixation System is 37 cm in length. The fasteners are designed with a 316L Stainless steel helical coil and polyetheretherketone (PEEK) cap on the proximal end to support mesh or tissue.
The provided document is a 510(k) premarket notification for the CapSure™ Permanent Fixation System. It focuses on demonstrating substantial equivalence to a predicate device (K142808 CapSure™ Permanent Fixation System) rather than presenting a study for initial market approval. Therefore, the information typically requested for a device's initial acceptance criteria and its demonstration through a study (especially regarding algorithm performance, ground truth establishment, sample sizes for training/test sets, and expert involvement for AI/diagnostic devices) is largely not applicable in this context.
This submission is about minor changes to an already cleared device, asserting that no technological characteristics have changed and that updated instructions for use are supported by adequate performance data from the previous 510(k).
However, I can extract the information related to performance data and acceptance criteria as presented for the original clearance (K142808) and affirmed for this submission.
Here's a breakdown based on the document:
1. Table of Acceptance Criteria and Reported Device Performance
| Test Category | Specific Test | Acceptance Criteria | Reported Device Performance |
|---|---|---|---|
| Biocompatibility | Cytotoxicity | (Implicit: Meet ISO 10993 standards for non-cytotoxic, non-sensitizing, non-irritating, non-pyrogenic, etc. for materials in contact duration categories) | All samples tested met the acceptance criteria.

VENTRALIGHT™ ST Mesh is indicated for use in the reconstruction of soft tissue deficiencies, such as for the repair of hernias.
The ECHO 2.0™ Lap System is intended to be used to facilitate the delivery of soft tissue prostheses during laparoscopic hernia repair.
The proposed ECHO 2.0™ Lap System with VENTRALIGHT™ ST Mesh is a low profile, bioresorbable, coated, permanent mesh, with a pre-attached removable positioning system, designed for the reconstruction of soft tissue deficiencies during laparoscopic ventral hernia renair.
VENTRALIGHT™ ST Mesh is a dual-component (absorbable and nonabsorbable) sterile prosthesis designed for the reconstruction of soft tissue deficiencies. The low profile mesh facilitates laparoscopic deployment and the pre-sized shapes offer ready-to-use benefits. VENTRALIGHT™ ST Mesh is co-knitted using polypropylene (PP) and polyglycolic acid (PGA) fibers to result in a two-sided mesh with a PP surface and a PGA surface. The mesh is coated on the PGA surface with a bioresorbable, chemically modified sodium hyaluronate (HA), carboxymethylcellulose (CMC) and polyethylene glycol (PEG) based hydrogel. The uncoated fascial side of the mesh allows for a prompt fibroblastic response through the interstices of the mesh, allowing for complete tissue ingrowth, similar to polypropylene mesh alone. The visceral side of the mesh is a bioresorbable coating that separates the mesh from underlying tissue and visceral organ surfaces to minimize tissue attachment to the mesh. Shortly after hydration, the biopolymer coating becomes a hydrated gel that is resorbed from the site in less than 30 days.
The VENTRALIGHT™ ST Mesh described above will be packaged pre-assembled to the ECHO 2.0TM Lap System. The ECHO 2.0™ Lap System is made of a deployment frame (pre-shaped nitinol wire encased in a thermoplastic coated nylon sleeve with a center hoisting loop) which is pre-attached to the VENTRALIGHT™ ST Mesh with connectors. Once inserted, the deployment frame facilitates laparoscopic deployment without the need of ancillary devices. Once initial mesh fixation is complete, the ECHO 2.0™ Lap System is completely removed from the body by cutting the center hoisting loop at the patient's skin level and pulling the deployment frame off the mesh and directly out of the abdominal cavity through a 10mm (or larger) trocar.
The provided text is a 510(k) Summary for a medical device (ECHO 2.0™ Lap System with VENTRALIGHT™ ST Mesh). It outlines the device description, indications for use, comparison to predicate devices, and performance data used to demonstrate substantial equivalence.
However, the document does not contain a table of acceptance criteria nor a detailed study description with specific numerical performance metrics, sample sizes, ground truth establishment, or expert qualifications that would typically be found in a study proving a device meets acceptance criteria. The performance data section lists the types of tests conducted, but not their results or specific acceptance thresholds.
Given the information provided, I cannot fulfill all parts of your request as the specific data regarding acceptance criteria and detailed study results are not present in this 510(k) summary. I can only describe the tests performed, not their outcomes or how they met specific acceptance criteria.
Here's a breakdown of what can be extracted from the text, and what is missing:
What can be extracted:
- Types of performance tests performed: Biocompatibility, Bench-top (simulated use, mesh integrity, ball burst, attachment strengths), Mechanical (nylon peel strength, hoisting loop attachment, crimp integrity), and Porcine Animal Model (simulated use, surgeon feedback).
- Absence of some types of studies: No electrical safety/EMC or software verification/validation were required as the device doesn't have such components. No clinical study was required.
- Intended Use & Indications for Use: The device is for reconstruction of soft tissue deficiencies (hernias), and the Lap System facilitates delivery of prostheses during laparoscopic hernia repair.
What is missing (and therefore cannot be provided in the table or detailed descriptions):
- Specific Acceptance Criteria: The document lists types of tests, but not the quantitative or qualitative criteria for success (e.g., "Ball Burst strength > X Newtons").
- Reported Device Performance: No actual results from the tests are provided, only that they were conducted "in support of the substantial equivalence determination."
- Sample Sizes: While tests were done, e.g., in a "porcine animal model," the number of animals or the number of samples for bench testing is not specified.
- Data Provenance: Not specified for bench tests. For biocompatibility, it states testing was conducted "in accordance with FDA Blue Book Memorandum #G95-1" and "leveraged from the primary predicate device." The animal model is porcine. The origin (country/institution) is not mentioned.
- Number of Experts/Qualifications for Ground Truth: Not applicable as specific ground truth data for performance metrics is not provided. Surgeon feedback was gathered for the porcine model, but details on "experts" or the number of surgeons are not given.
- Adjudication Method: Not applicable.
- MRMC Comparative Effectiveness Study: Explicitly states "No clinical study was required." This implies no MRMC study.
- Standalone Performance: While "Performance Testing - Bench" and "Performance Testing - Mechanical" describe tests on the device itself, the results establishing its standalone performance against defined acceptance criteria are not provided.
- Type of Ground Truth Used: For the porcine model, it's "surgeon feedback on product performance." For other tests, it would typically be defined metrics based on engineering specifications or ISO standards, but these are not detailed.
- Sample Size for Training Set: Not applicable as this is a physical medical device, not an AI/software device. The document explicitly states "The proposed ECHO 2.0™ Lap System with VENTRALIGHT™ ST Mesh does not contain software."
- Ground Truth for Training Set: Not applicable.

4. Adjudication method for the test set:
- Not applicable/Not provided.
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:
- No. The document explicitly states: "No clinical study was required in support of the proposed ECHO 2.0™ Lap System with VENTRALIGHT™ ST Mesh." This device is a physical surgical mesh and delivery system, not an AI or imaging device, so an MRMC study is not relevant.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

The Modified ONFLEX™ Mesh is indicated for use in the reinforcement of soft tissue where weakness exists, such as in the repair of inguinal hernias.
The proposed Modified ONFLEX™ Mesh is a self-expanding, non-absorbable, sterile (Ethylene Oxide) prosthesis, made from monofilament polypropylene mesh and has a lightweight large pore design. This construction allows a prompt fibroblastic response through the interstices of the mesh as observed in a preclinical model, which may not correlate to performance in humans. The Modified ONFLEX™ Mesh has an anatomical shape designed to cover potential defect areas.
The Modified ONFLEX™ Mesh also contains two pockets to facilitate insertion and positioning of the device. The positioning pockets are located on the larger medical apex of the mesh and the lateral apex of the mesh. In addition to the pocket, the mesh also contains straps to facilitate positioning and fixation of the device. The Modified ONFLEX™ Mesh comes packaged with an onlay which is available in one size and is optional based on surgeon preference.
The proposed device contains SorbaFlex™ Memory Technology comprised of an absorbable PDO monofilament which forms an interrupted ring. SorbaFlex™ Memory Technology provides memory and stability to the device, facilitating ease of initial insertion and proper placement of the device. The PDO monofilament is folded and welded onto itself at the ends. The interrupted ring provides memory and stability to the device, facilitating ease of initial insertion and proper placement of the device. The PDO monofilament fully degrades by means of hydrolysis in vivo in 6 - 8 months. The PDO monofilament is dyed violet by adding D & C Violet No. 2. The interrupted ring is placed within a mesh tube constructed from a knitted polypropylene monofilament. The purpose of the mesh tube is to contain the interrupted recoil ring during the degradation process. The interrupted ring, contained in the mesh tube, is sewn between two layers of mesh with polytetrafluoroethylene (PTFE) monofilament.
The Modified ONFLEX™ Mesh is offered in two sizes: medium (0115610) and large (0115611). The proposed Modified ONFLEX™ Mesh is considered a tissue contacting permanent implant according to Blue Book Memorandum issued on May 1, 1995, Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing".
The provided text describes a 510(k) premarket notification for a medical device called "Modified ONFLEX Mesh." This document focuses on demonstrating that the new device is "substantially equivalent" to legally marketed predicate devices, rather than establishing acceptance criteria or reporting specific device performance metrics in a quantifiable table format.
Therefore, many of the requested details, such as specific numerical acceptance criteria, reported performance values, sample sizes for test sets, number of experts, adjudication methods, MRMC studies, standalone performance, and ground truth types/methods for training sets, are not explicitly mentioned in this document. This type of regulatory submission primarily focuses on comparing the new device's design, materials, and intended use to existing, cleared devices.
Here's an attempt to answer the questions based only on the provided text, indicating where information is not available:

The ONFLEX™ Mesh is indicated for use in the reinforcement of soft tissue where weakness exists, such as in the repair of inguinal hernias.
The proposed ONFLEX™ Mesh is a self-expanding, non-absorbable, sterile (Ethylene Oxide) prosthesis, made from monofilament polypropylene mesh and has a lightweight large pore design. This construction allows a prompt fibroblastic response through the interstices of the mesh as observed in a preclinical model. which may not correlate to performance in humans. The ONFLEX™ Mesh has an anatomical shape designed to cover potential defect areas. The ONFLEX™ Mesh also contains a pocket on the larger medial apex of the mesh to facilitate insertion and positioning of the device.
The proposed device contains SorbaFlex™ Memory Technology comprised of an absorbable PDO monofilament which forms an interrupted ring. SorbaFlex™ Memory Technology provides memory and stability to the device, facilitating ease of initial insertion and proper placement of the device. The PDO monofilament is folded and welded onto itself at the ends. The interrupted ring provides memory and stability to the device, facilitating ease of initial insertion and proper placement of the device. The PDO monofilament fully degrades by means of hydrolysis in vivo in 6 - 8 months. The PDO monofilament is dyed violet by adding D & C Violet No. 2. The interrupted ring is placed within a mesh tube constructed from a knitted polypropylene monofilament. The purpose of the mesh tube is to contain the interrupted recoil ring during the degradation process. The interrupted ring, contained in the mesh tube, is sewn between two lavers of mesh with polytetrafluoroethylene (PTFE) monofilament.
The ONFLEX™ Mesh has a blue limit line at the lateral portion of the mesh, composed of polypropylene monofilament dyed with Phthalocyaninato(2-) copper colorant, to provide visual feedback for where the device can be tailored. The ONFLEX™ Mesh can be tailored at the opening of the interrupted ring or outside of the blue limit line.
The ONFLEX™ Mesh is offered in two sizes: medium (0115410) and large (0115411). The proposed ONFLEX™ Mesh is considered a tissue contacting permanent implant according to Blue Book Memorandum issued on May 1, 1995, Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing".
The provided document is a 510(k) summary for a medical device called ONFLEX™ Mesh. It does not present acceptance criteria or a study proving the device meets specific acceptance criteria in the way one would describe for an AI/ML powered device.
Instead, the document focuses on demonstrating substantial equivalence to existing predicate devices based on:
- Indications for Use: The ONFLEX™ Mesh is indicated for use in the reinforcement of soft tissue where weakness exists, such as in the repair of inguinal hernias, which is similar to the predicate devices.
- Technological Characteristics: The device has similar construction materials (polypropylene monofilament),
large pore knit, anatomical shape, and other features, with some modifications from its predicates. - Performance Data: This includes biocompatibility testing, mechanical testing, and animal studies, all used to show similar performance to the predicates.
Therefore, I cannot fulfill the request as it pertains to acceptance criteria and study details for an AI/ML device. The document describes a traditional medical device (surgical mesh) and its regulatory clearance process, which relies on demonstrating substantial equivalence rather than meeting pre-defined performance acceptance criteria for an AI/ML algorithm.
However, I can extract information about the performance data used to support the substantial equivalence claim, which can be seen as analogous to demonstrating that the device performs similarly to its predecessors.
Here's a breakdown of the performance data presented, formatted to align with your request where possible, but with the understanding that it's not a study proving meeting acceptance criteria in the AI/ML sense:
1. A table of performance characteristics reviewed (not "acceptance criteria"):
| Performance Characteristic | Reported Device Performance/Comparison |
|---|---|
| I. Biocompatibility Testing | |
| Cytotoxicity | Leveraged from predicate devices (Bard® 3DMax™ Light Mesh and Bard® Ventrio™ Hernia Patch) |
| Sensitization | Leveraged from predicate devices |
| Intracutaneous reactivity | Leveraged from predicate devices |
| Acute systemic toxicity | Leveraged from predicate devices |
| Subchronic toxicity | Leveraged from predicate devices |
| Genotoxicity | Leveraged from predicate devices |
| Implantation | Leveraged from predicate devices |
| II. Electrical Safety/EMC | Not applicable – no electrical or metal components. |
| III. Software V&V | Not applicable – does not contain software. |
| IV. Mechanical Testing | Performed to compare proposed ONFLEX™ Mesh to predicates (3DMax™ Light Mesh and Ventrio™ Hernia Patch), showing similar characteristics. |
| Mesh weave characteristics | Measured and compared to predicates. |
| Mesh thickness | Measured and compared to predicates. |
| Mesh pore size | Measured and compared to predicates. |
| Mesh density | Measured and compared to predicates. |
| Mesh stiffness | Measured and compared to predicates. |
| Ball burst strength | Measured and compared to predicates. |
| Suture pullout strength | Measured and compared to predicates. |
| Tear strength | Measured and compared to predicates. |
| PDO monofilament tensile strength | Measured and compared to predicates. |
| Simulated deployment test | Measured and compared to predicates. |
| V. Animal Study | In vivo and in vitro resorption studies performed to characterize mechanical strength and resorption of PDO monofilament in SorbaFlex™ Memory Technology. Studies were originally conducted for predicate Ventrio™ Hernia Patch (K081777) and adopted for ONFLEX™ Mesh (which contains the same PDO monofilament). |
| VI. Clinical Study | No clinical study was required. |
2. Sample sized used for the test set and the data provenance:
- Test Set Size: Not specified in terms of fixed sample sizes for a 'test set' as would be done for an AI/ML evaluation. The mechanical testing was performed on the ONFLEX™ Mesh and predicate devices. Biocompatibility and animal studies were leveraged from the predicate devices.
- Data Provenance: Not explicitly stated as retrospective or prospective for the mechanical tests, but implied to be conducted for the submission. Biocompatibility and animal studies were previously conducted for the predicate devices. The country of origin of data is not specified but implicitly US for regulatory purposes.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. This is not an AI/ML device relying on expert-established ground truth. The "ground truth" for substantial equivalence is based on established scientific principles for material properties, biocompatibility, and mechanical performance, often standardized through guidance documents and international standards.
4. Adjudication method for the test set:
- Not applicable. No adjudication method is described for this type of 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. This is not an AI-powered diagnostic/interpretative device.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a surgical mesh; it does not have an algorithm.
7. The type of ground truth used:
- For Biocompatibility: Compliance with FDA Blue Book Memorandum #G95-1 / ISO 10993-1 standards (biological evaluation through established tests for cytotoxicity, sensitization, etc.).
- For Mechanical Testing: Comparison of physical and performance characteristics against predicate devices, based on "FDA Guidance for the Preparation of a Premarket Notification Application for a Surgical Mesh, issued March 2. 1999." The "ground truth" is established engineering and material science principles and the performance of existing, cleared predicate devices.
- For Animal Study (Resorption): In vivo and in vitro studies establishing the mechanical strength and resorption profile of the PDO monofilament, referenced from the predicate device submission.
8. The sample size for the training set:
- Not applicable. There is no training set for this device in the context of AI/ML.
9. How the ground truth for the training set was established:
- Not applicable.

The PERMASORB™ Disposable Fixation Device is indicated for the approximation of soft tissue and fixation of surgical mesh to tissues during open or laparoscopic surgical procedures, such as hernia repair.
PermaSorb™ is endoscopic or open surgical stapler composed of a disposable sterile single use delivery instrument and resorbable fixation devices.
The provided text is a 510(k) summary for the PERMASORB™ Disposable Fixation Device. It describes the device, its indications for use, and a comparison to predicate devices, but it explicitly states that "No clinical studies were performed."
Therefore, based on the provided text, there is no information available to construct a table of acceptance criteria or describe a study that proves the device meets those criteria. The submission relies solely on non-clinical testing summary (which states "No changes to product design specifications were made") and substantial equivalence to predicate devices (K060494 and K111153) to demonstrate safety and effectiveness.
Key takeaway from the document: The device approval is based on substantial equivalence, not a new study demonstrating performance against specific acceptance criteria.

The Phasix™ Plug and Patch is indicated for reinforcement of soft tissue, where weakness exists, in procedures involving soft tissue repair, such as groin hernia defects.
The proposed Phasix™ Plug and Patch utilizes a fully resorbable poly-4-hydroxybutrate (P4HB) polymer material pre-formed into a three-dimensional (cone shape) configuration constructed of a fluted outer layer and multiple inner layers (petals) of mesh attached at the tip. The inner petals and cones are sewn together at the tip with a single P4HB monofilament thread. The inner petals allow the device to conform readily to defects of various sizes while the structure of the small inter-fiber pores of the P4HB mesh allows for a prompt fibroblastic response and allows tissue in-growth. The cone shape configuration of the device allows it to expand and reduce in conformation with the immediate anatomy so that the repair is tension-free. The petals can be removed to customize the Phasix Plug to each individual patient. The Phasix Plug is available in several sizes. A flat mesh onlay patch is packaged with each Phasix Plug. The onlay is also fully resorbable and is made from the same P4HB monofilament as the Phasix Plug. Unlike the plug, the onlay patch is available in only one size but is customizable.
The provided text describes the Phasix™ Plug and Patch device and its predicate devices, focusing on demonstrating substantial equivalence. However, it does not contain the specific type of information requested about acceptance criteria and a study proving a device meets those criteria, particularly in the context of an AI/algorithm-driven device.
The document is a 510(k) summary for a surgical mesh, which is a physical medical device, not an AI or algorithm-based diagnostic tool. Therefore, many of the requested points (e.g., sample size for test/training sets, number of experts for ground truth, MRMC study, standalone algorithm performance) are not applicable or not present in this type of submission for a physical surgical implant.
Here's a breakdown based on the information available in the provided text, and where it falls short of your request:
1. Table of Acceptance Criteria and Reported Device Performance
This information is not explicitly provided in the format requested for a quantifiable acceptance criteria and performance metrics. The document broadly states that "performance testing demonstrates that these differences do not adversely affect the safety and effectiveness of the proposed device."
Instead of a table with specific acceptance criteria, the document describes the types of tests performed:
- Bench Testing:
- Physical characteristics: mesh weave, mesh pore size, device density, device thickness, device stiffness.
- Performance evaluations: burst strength, tear resistance, suture pullout strength.
- Preclinical Studies:
- Porcine model (simulated ventral hernia repair): mechanical analysis, histological analysis, molecular weight properties post-implantation.
- In-vivo rat study: percentage area mesh contracture and host inflammatory/fibrotic response post-implantation.
- Biocompatibility Testing: Conducted according to ISO 10993-1 standards.
The document concludes that "All test results provided in this submission support the safety and effectiveness of the proposed Phasix Plug and Patch device for its intended use and demonstrate that the proposed Phasix Plug and Patch device is substantially equivalent to its predicate devices, PerFix Light Plug and TephaFlex Mesh." This is the general acceptance criterion for a 510(k) submission – demonstrating substantial equivalence to a legally marketed predicate device.
2. Sample Size for the Test Set and Data Provenance
- Sample Size: Not specified for any of the individual tests. The text mentions a "comprehensive study... in a porcine model" and "An in-vivo study... in rats," but doesn't give numbers of animals used.
- Data Provenance: Not specified for individual tests. The studies are described as "preclinical" and "in-vivo," indicating animal model testing rather than human clinical data. The country of origin of the data is not mentioned.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
N/A. This document describes a physical medical device, not a diagnostic algorithm that would require expert-established ground truth from images or other data. The "ground truth" here would be the physical measurements, biological responses in animal models, and integrity of the device itself.
4. Adjudication Method for the Test Set
N/A. As above, this is not applicable for the type of device and studies described.
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
N/A. This is a physical surgical mesh, not an AI or imaging diagnostic device. No human readers or AI assistance are involved in its performance or evaluation in this context.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
N/A. This is not an algorithm.
7. The type of ground truth used
The "ground truth" for this device's evaluation would be:
- Pre-defined physical specifications (e.g., mesh weave, pore size, density, thickness, stiffness).
- Quantifiable mechanical properties (e.g., burst strength, tear resistance, suture pullout strength).
- Biological outcomes in animal models (e.g., mechanical analysis, histological analysis, molecular weight properties post-implantation, percentage area mesh contracture, host inflammatory/fibrotic response).
- Biocompatibility as defined by ISO 10993-1 standards.
8. The sample size for the training set
N/A. This is not an AI/ML device that requires a "training set."
9. How the ground truth for the training set was established
N/A. Not an AI/ML device.
In summary: The provided document is a 510(k) summary for a surgical mesh, which evaluates the physical and biological properties of the device to demonstrate substantial equivalence to predicate devices. It does not contain the information points typically associated with the development and validation of an AI/algorithm-driven device like acceptance criteria based on diagnostic performance, expert-established ground truth, or multi-reader studies.

The Bard LabSystem™ EP Laboratory is a computer and software driven data acquisition and analysis tool designed to facilitate the gathering, display, analysis by a physician, pace mapping and storage of cardiac electrophysiologic data.
When integrated with the Biosense Webster® CARTO™ 3 system, the Bard® LabSystem™ PRO EP Recording System is designed to: a) send patient demographics to Biosense Webster® CARTO™ 3, and b) acquire (from Biosense Webster® CARTO™ 3), store and display: i) synchronized 3D mapping events, ii) stimulation pacing data, and iii) images of completed 3D electro-anatomical maps of the human heart. The 3D mapping events and images are created by the Biosense Webster® CARTO™ 3 device and stored on the Bard® LabSystem™ PRO EP Recording System for review and insertion into the final clinical report. Integration also supports bidirectional communication of stimulation pacing channel selection and information sharing between the two systems.
The V2.6 software for the LabSystem™ PRO EP Recording System is a bidirectional software interface that links the Bard LabSystem PRO EP Recording System with the Biosense-Webster CARTO 3 mapping/navigation system. The V2.6 software also incorporates the core recording system functionality of the released V2.4b software for the LabSystem PRO EP Recording System. The joint integrated solution provides a single repository for the resulting CARTO 3D electro-anatomical map and procedure information collected by LabSystem PRO EP Recording System. This interface will enhance the usability of the two systems when used in tandem. This will result in a workflow improvement, more streamlined data management, and simpler review of case details. The information will be shared via a network link using a BWI communication protocol.
The V2.6 software is intended for use with the LabSystem PRO EP Recording System (K031000). The LabSystem™ PRO EP Recording System is a microprocessor based data acquisition system that is used during electrophysiology procedures to acquire ECG, intracardiac, pressure and digital data from other devices like fluoroscopic systems and RF generators. The ECG, intracardiac and pressure data are acquired by an amplifier that is connected to the patient via ECG leadwires and catheters. It does not transmit alarms nor does it have arrhythmia detection capabilities.
This document is a 510(k) summary for the V2.6 software for the Bard LabSystem PRO EP Recording System, which is a programmable diagnostic computer used in electrophysiology procedures. The submission focuses on demonstrating substantial equivalence to predicate devices and does not contain details about specific acceptance criteria or a clinical study in the format requested.

-
A table of acceptance criteria and the reported device performance
- Acceptance Criteria: The document states that "Software qualification is performed in-house on the System with results that meet acceptance criteria, thus confirming the safety and effectiveness of each functional aspect of the LabSystem™ PRO EP Recording System." However, the specific acceptance criteria (e.g., performance metrics, thresholds) are not detailed in this summary.
- Reported Device Performance: No specific performance metrics or quantitative results are provided in this summary. The document focuses on demonstrating functional equivalence and adherence to standards.
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- This information is not available in the provided 510(k) summary. It describes "Software qualification" being performed "in-house," but does not specify sample sizes for testing or data provenance.
-
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 available. The document does not describe the establishment of ground truth by experts for a test set.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set
- This information is not available. No adjudication method is mentioned.
-
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 is not applicable/not available. The device (LabSystem™ PRO EP Recording System software) is not an AI-assisted diagnostic tool that would typically undergo an MRMC study comparing human readers with and without AI. It's a data acquisition, display, and integration system.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not explicitly applicable in the context of an "algorithm-only" performance as one might see for an AI diagnostic tool. The "software qualification" mentioned is an in-house verification and validation process for the software's functionality and integration capabilities. The device itself is a system for acquiring and displaying data for physician analysis.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- This information is not available. The concept of "ground truth" as used in clinical performance studies is not detailed for this type of software verification. The testing would likely focus on functional accuracy (e.g., data transfer integrity, correct display of information, proper integration).
-
The sample size for the training set
- This information is not available. This device's software (V2.6) for data acquisition and integration does not appear to involve a "training set" in the sense of machine learning algorithms. Its development and testing would involve traditional software engineering verification and validation.
-
How the ground truth for the training set was established
- This information is not available, as no training set (in the machine learning sense) is mentioned or implies.
Summary of what is available regarding "acceptance criteria" and "study":
- Acceptance Criteria Mentioned: The document states that "Software qualification is performed in-house on the System with results that meet acceptance criteria, thus confirming the safety and effectiveness of each functional aspect of the LabSystem™ PRO EP Recording System."
- Study Described: The core study mentioned is "Software qualification performed in-house." This is not a clinical study but rather a non-clinical verification and validation process.
- Standards Referenced for Software Development/Testing:
- IEEE Standard 730-1995 Software Quality Assurance Plans
- IEEE Standard 829-1983 Software Test Documentation
- IEEE Standard 1012-1986 Software Verification and Validation Plans
- IEEE Standard 830-1993 Software Requirement Specifications
- IEEE Standard 1008-1987 Software Unit Testing
- EN 60601-1-2:2007 EMC, Radiated emissions and Conducted emissions requirements
- EN 60601-1:2005 Patient Leakage current (Section 19, Table IV, Type CF, 50uA)
- Conclusion of Study: The non-clinical testing confirmed the safety and effectiveness of each functional aspect of the system, supporting the claim of substantial equivalence to predicate devices based on "same Indications for Use, principles of operation, and the technological characteristics."
This 510(k) submission is for a software update to an existing electrophysiology recording system, primarily focusing on integration capabilities. The "study" referenced is standard software verification and validation, not a clinical performance study with "ground truth" and "readers" in the context of diagnostic AI.
