For use in those patients with cardiovascular defects wherein accurate measurement . I of the defect is important to select the appropriately sized occluder device.

The NuMED, Inc. PTS X™ Sizing Balloon catheter is a coaxial catheter for use in those patients with cardiovascular defects wherein accurate measurement of the defect is important to select the appropriately sized occluder device. The outer body is made of polymeric tubing, and the inner tubing is comprised of a multi layer extrusion of polyamide (Vestamid PA12) that surrounds a braid of 304 LV Stainless Steel. The catheter features a proximal end bifurcate with two distinct luminal passages. The inflation lumen terminates into a distally mounted balloon. This balloon is of the non-compliant variety and will have a typical single wall thickness of 0.0004". This balloon is designed to insert through the smallest possible introduction sleeve. The through lumen terminates at the tip of the catheter and will accept the passage of the appropriate guidewire. This lumen has radiopaque platinum marker bands under the balloon shoulders for placement using fluoroscopy. Additionally, there are two radiopaque platinum marker bands spaced at 10mm (as measured from leading edge to leading edge). These bands are located at the balloon center and are used as a distance reference. The catheter is white in color and the balloon material is clear. The catheter balloon diameter is stamped onto the Y sleeve and the balloon extension is labeled with balloon diameter x balloon length x introducer size x shaft size x usable length x guidewire size and the catheter lot number. The catheter is packaged in a polyethylene loop and is double packed in two heat sealed Tyvek pouches.

The provided text is a clearance letter from the FDA for the NuMED PTS X Sizing Balloon Catheter, not a study report. Therefore, it does not contain information about acceptance criteria, device performance, sample sizes, ground truth establishment, or multi-reader multi-case studies.

The document primarily states that the device is substantially equivalent to a legally marketed predicate device (NuMED PTS Catheter) based on its intended use and material similarity. It outlines the regulatory classification and general requirements for the device.

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

• No clinical study or performance data: The letter focuses on the regulatory clearance process and substantial equivalence, not on a detailed study proving performance against specific acceptance criteria.
• No mention of acceptance criteria: Specific metrics for device performance (e.g., accuracy of measurement, safety rates) that would constitute "acceptance criteria" are not listed.
• No device performance metrics: The document describes the device and its intended use but does not provide quantitative or qualitative data on how well it performs its function.
• No sample size for test set: No clinical or laboratory test results are detailed with sample sizes.
• No data provenance: Information on the origin of data (if any), such as geographical location or retrospective/prospective nature, is absent.
• No expert involvement: There is no mention of experts establishing ground truth or their qualifications.
• No adjudication method: This would be relevant to evaluating expert consensus, which isn't discussed.
• No MRMC study: The document does not describe any study involving human readers or AI assistance.
• No standalone algorithm performance: This device is a physical catheter, not an algorithm, so standalone algorithm performance is not applicable.
• No type of ground truth used: Since no performance study is described, there's no mention of ground truth.
• No sample size for training set/ground truth for training set: These concepts are typically relevant to AI/machine learning models, which this device is not. The "training" for this device would be its design and manufacturing processes, not data training.

In summary, the provided document is a regulatory clearance letter, not a study report. It does not contain the information required to populate the table or answer the specific questions about acceptance criteria, study details, and device performance.

This catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac, and renal arteries. These catheters are not designed to be used in the coronary arteries.

The Mullins X™ catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac and renal arteries. The catheter is a coaxial over the wire catheter with a balloon near the distal tip. One lumen permits guidewire insertion to facilitate advancement of the catheter, while the other lumen is for balloon inflation and deflation.

The balloons of the MULLINS X™ PTA Catheter are made of a non-compliant polymeric material. The two laminate balloon system is designed to inflate to a specific diameter at a given pressure. The change in diameter is minimal over the range of inflation pressures. The balloons are heat bonded to the shaft.

The outer body is made of polymeric tubing, and the inner tubing is comprised of a multi layer extrusion of polyamide (Vestamid PA12) that surrounds a braid of 304 LV Stainless Steel. The area under the balloon is enhanced with five radiopaque platinum image bands. Two that are 5mm on each side of the balloon center and two more under the balloon shoulders. An additional image band is imbedded into the tip of the catheter as an additional safety measure.

The catheter is white in color and the balloon material is clear. The catheter balloon diameter and name is stamped onto the Y sleeve and the balloon extension is labeled with balloon diameter x balloon length x introducer size x shaft size x usable length x guidewire size and the catheter lot number. The catheter is packaged in a polyethylene sheath and is double packed in two heat sealed Tyvek pouches.

The provided document is a 510(k) premarket notification for a medical device (NuMED Mullins X PTA Catheter), which primarily focuses on demonstrating substantial equivalence to a predicate device based on manufacturing specifications, materials, and intended use. It does not contain information about clinical studies, device performance in terms of efficacy or diagnostic accuracy, or specific acceptance criteria and their achievement through studies in the way a diagnostic AI device submission would.

Therefore, I cannot extract the requested information regarding acceptance criteria, study details, sample sizes, expert ground truth adjudication, MRMC studies, standalone performance, or training set details. This document describes a medical device for a physical intervention (PTA catheter), not a diagnostic algorithm or AI system.

I reiterate that the provided text does not contain any information about acceptance criteria or studies proving device performance related to diagnostic accuracy, AI, or human reader improvement.

The document does mention:

• Biocompatibility Testing: Materials used are the same as previously approved devices (K931009, K991977) which were tested for biocompatibility in compliance with the Tripartite Biocompatibility Guidance for Medical Devices. Test results are on file at NuMED, Inc.
• Laboratory (Bench) Testing: All bench testing was performed in accordance with GMP's and results are kept on file at NuMED, Inc.

However, these are general statements about compliance and are not the type of detailed performance studies asked for in the user's prompt (which implies a diagnostic or AI-driven device context).

The Z-MED II catheter is available in standard diameters from 4 mm to 30 mm in standard lengths of 2 cm to 10 cm. Guidewire sizes will vary from 0.025" to 0.035" and shaft sizes will vary from 5F to 9F.

The provided document describes a 510(k) premarket notification for the NuMED Tyshak II and Z-Med II PTV Catheters, which modifies previously approved devices by introducing new lengths. Since this is a 510(k) submission, the primary goal is to demonstrate substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria through a clinical trial or extensive standalone algorithm testing.

Therefore, many of the typical sections you'd expect for AI/algorithm performance studies (like sample size for test sets, number of experts, adjudication methods, MRMC studies, standalone performance with metrics like sensitivity/specificity, or training set details) are not applicable or explicitly mentioned in this type of submission. The focus is on demonstrating that the new device (with extended lengths) is as safe and effective as the predicate device already on the market.

Here's an analysis based on the provided text, addressing your points where possible:

1. Table of Acceptance Criteria and Reported Device Performance

For a 510(k) submission focused on modifications to an existing device, "acceptance criteria" are typically related to maintaining the same performance characteristics as the predicate device. The document states that the new models are "very similar in construction" to the predicate devices, with specific differences (thinner balloon for Tyshak II, thicker balloon material for Z-MED II) and new lengths.

The primary "performance" demonstrated here is the meeting of biocompatibility and bench testing standards, implying that the modified devices perform equivalently to the predicate devices in these aspects. There are no explicit performance metrics (e.g., success rates in procedures) measured against numerical acceptance criteria presented in this specific document.

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

Not applicable for this type of submission. There is no mention of a "test set" in the context of clinical data for AI/algorithm performance. The biocompatibility and bench testing are presumably performed on a sample of the manufactured devices, but specific sample sizes for these tests are not provided and are internal to NuMED, Inc. The document states "Test results indicate that all materials demonstrate the biocompatibility... and are on file at NuMED, Inc." and "All bench testing was performed in accordance with GMP's and the results are kept on file at NuMED, Inc." This indicates the provenance is internal data from NuMED's labs from their testing.

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

Not applicable. This device is a catheter, not an AI or diagnostic algorithm requiring expert-established ground truth from medical images or clinical outcomes in a test set.

4. Adjudication Method for the Test Set

Not applicable, as there is no "test set" in the context of clinical data requiring expert adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is a medical catheter, not an AI-assisted diagnostic tool.

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

Not applicable. This is a physical medical device.

7. The Type of Ground Truth Used

For biocompatibility, the "ground truth" is compliance with established biological safety standards for medical device materials. For bench testing, the "ground truth" is adherence to engineering specifications and performance parameters demonstrated as safe and effective for the predicate device. These are established through standardized testing protocols (e.g., ISO, ASTM).

8. The Sample Size for the Training Set

Not applicable. There is no AI algorithm involved, thus no "training set."

9. How the Ground Truth for the Training Set was Established

Not applicable.

Ask a specific question about this device

This catheter is recommended for Percutaneous Transluminal Valvuloplasty (PTV) of the pulmonary valve.

• A patient with isolated pulmonary stenosis
• A patient with valvular pulmonary stenosis with other minor congenital heart disease that does not require surgical intervention.

The COEfficient PTV Catheter is a coaxial over-the-wire catheter with a balloon near the distal tip. One lumen permits guidewire insertion to facilitate advancement of the catheter into the pulmonary valve while the other lumen is for balloon inflation and deflation. The balloon of the COEfficient model is made of a non-compliant polyethylene. The balloons are designed to inflate to a specific diameter at a given pressure. The change in diameter is minimal over the range of inflation pressures. The catheter body ends proximally in a bifurcated 'Y' connector with a guidewire port and a balloon extension. The balloon extension is marked with the product lot number and the balloon size. The outer body and inner body tubing is made of pebax. The area under the balloon is enhanced with either one or two radiopaque platinum image bands depending on the model. If marked with one image band, it is centered under the midpoint of the balloon. If it is marked with two image bands, they are located under the shoulders of the balloon. This catheter is of the same design and construction as the NuMED PTV catheters for which the 510(K) has been approved. The differences are lower profile, smaller shaft, and higher rated burst pressure.

Here's an analysis of the provided text regarding the NuMED COEfficient PTV Catheter, focusing on acceptance criteria and study information:

Based on the provided Summary of Safety and Effectiveness Data for the NuMED COEfficient PTV Catheter (K014124), the device's acceptance criteria and studies primarily revolve around demonstrating substantial equivalence to a predicate device and meeting biocompatibility and bench testing standards.

It's important to note that this document is a 510(k) summary, which typically focuses on demonstrating equivalence rather than an independent clinical study proving efficacy against specific quantitative clinical outcomes.

1. Table of Acceptance Criteria and Reported Device Performance

Given that this is a 510(k) submission based on substantial equivalence, the "acceptance criteria" are implicitly defined by the characteristics of the predicate device, the NuMED Z-MED PTV Catheter. The device performance is reported as meeting or being comparable to these characteristics, with specific improvements highlighted.

• Introducer: 4 Fr - 7 Fr (Lower Profile)
• Shaft Size: 3.5 Fr (Smaller Shaft)
• Guidewire Size: 0.018"
• Usable Length: 75 cm
• Balloon Diameter: 4 mm - 12 mm
• Balloon Length: 2 cm - 4 cm |
  | Rated Burst Pressure | Implicitly, a safe and effective burst pressure for intended use. | Improved: Higher rated burst pressure (stated qualitatively compared to predicate). |

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

The document does not describe a clinical "test set" in the traditional sense of a patient cohort. The support for the device largely comes from:

• Materials Biocompatibility Testing: The "test set" here would refer to the materials themselves. The document states the materials were tested, but does not specify the sample size of material samples or the specific tests performed (though it references the Tripartite Biocompatibility Guidance).
• Laboratory (Bench) Testing: The "test set" here refers to the device units subjected to various bench tests (e.g., burst pressure, dimensional accuracy). The document states "All bench testing was performed," but does not specify the sample size of devices tested for each parameter.
• Comparison to Predicate: The "test set" is effectively the design and performance specifications of the NuMED COEfficient PTV Catheter compared to the NuMED Z-MED PTV Catheter.

Data Provenance: The data provenance is internal to NuMED, Inc. (Hopkinton, NY, USA), with testing described as being performed in accordance with GMPs (Good Manufacturing Practices). This constitutes retrospective evaluation against established standards and comparison to a previously approved device. There is no indication of prospective patient data collection for this 510(k) submission.

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

This type of information is not applicable to this submission. The ground truth for biocompatibility is established by standardized testing protocols (e.g., ISO standards referenced by the Tripartite Guidance). The ground truth for bench testing (e.g., burst pressure, dimensions) is established by engineering specifications and direct measurement, not expert consensus. For substantial equivalence, the "ground truth" is the established safety and effectiveness of the predicate device, which would have been determined at its time of approval.

4. Adjudication Method for the Test Set

Not applicable. There is no clinical test set requiring expert adjudication for this 510(k) submission.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This device is a physical medical device (catheter), not an AI/imaging diagnostic tool, and the submission is for substantial equivalence rather than a comparative clinical effectiveness trial. Therefore, an effect size of human readers improving with/without AI assistance is not relevant or provided.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

No, a standalone algorithm study was not done. This is a physical medical device, not a software algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this 510(k) submission is established by:

• Predicate Device Equivalence: The primary ground truth is the established safety and effectiveness of the NuMED Z-MED PTV Catheter, to which the COEfficient PTV Catheter is demonstrated to be substantially equivalent.
• Standardized Bench Test Results: Objective measurements against engineering specifications (e.g., burst pressure, dimensions, inflation characteristics).
• Biocompatibility Standards: Compliance with recognized international and national guidelines for biocompatibility (Tripartite Biocompatibility Guidance).

There is no mention of expert consensus, pathology, or outcomes data from a clinical trial for establishing the ground truth for this specific submission, as it relies on equivalence to a predicate.

8. The Sample Size for the Training Set

Not applicable. This is a physical medical device, not an AI or machine learning model that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. As above, there is no training set for this device.

Ask a specific question about this device

This catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac, and renal arteries. These catheters are not designed to be used in the coronary arteries.

The NuMED, Inc. MULLINS™ PTA Catheter is a co-axial over-the-wire catheter with a balloon near the distal tip. It is available in sizes of 12-20mm diameter and 3-4cm in length. One lumen permits guidewire insertion to facilitate advancement of the catheter, while the other lumen is for balloon inflation and deflation. The balloons of the NuMED, Inc. MULLINS™ PTA Catheter is made of a noncompliant polymeric material and are the same balloons that are used on the approved Z-MED Catheter (K931009, K991977, and K011557). The two laminate balloon system is designed to inflate to a specific diameter at a given pressure. The change in diameter is minimal over the range of inflation pressures. The balloons are heat bonded to the shaft. The outer body and inner body tubing are made of polymeric tubing. The area under the balloon is enhanced with five radiopaque platinum image bands. Two that are 5mm on each side of the balloon center and two more under the balloon shoulders. An additional image band is imbedded into the tip of the catheter as an additional safety measure.

This document is a 510(k) premarket notification for the NuMED Mullins PTA Catheter. It claims substantial equivalence to the NuMED Z-MED PTA Catheter. The information provided is primarily focused on the device description, biocompatibility, and bench testing, rather than explicit acceptance criteria and a detailed study report with performance metrics.

Here's an analysis based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Based on the document, direct, quantifiable acceptance criteria with corresponding performance results are not explicitly stated in a table format. The submission relies on demonstrating substantial equivalence to a predicate device by comparing design, materials, and intended use. The "acceptance criteria" can be inferred as meeting the standards and performance of the predicate device and relevant biocompatibility/bench testing.

Missing specific quantifiable acceptance criteria and performance data. The document states that test results are "on file at NuMED, Inc.", indicating that the detailed data was submitted to the FDA but is not included in this summary.

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

• Sample Size: Not specified. The document only mentions "Biocompatibility Testing" and "Laboratory (Bench) Testing" without indicating the number of devices or components tested.
• Data Provenance: The tests were conducted internally by NuMED, Inc. ("on file at NuMED, Inc."). The document does not specify the country of origin of the data beyond "NuMED, Inc.", which is based in Hopkinton, NY, USA. The testing appears to be retrospective in the sense that the results were submitted for a premarket notification for a device that has undergone testing.

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

This type of information is not applicable to this submission. The device is a medical catheter, and its evaluation relies on physical and material properties, mechanical testing, and biocompatibility, not on expert interpretation of medical images or clinical data to establish a ground truth for a diagnostic output.

4. Adjudication Method for the Test Set

This is not applicable for the reasons stated above. There's no "ground truth" established by experts or adjudication involved in the type of testing described (biocompatibility, bench testing).

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

This is not applicable. The device is a medical catheter, not an AI-powered diagnostic tool requiring human readability or interpretation. Therefore, there's no comparison of human readers with and without AI assistance.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

This is not applicable. The device is a physical medical instrument, not an algorithm or AI system.

7. Type of Ground Truth Used

The "ground truth" for this device's safety and effectiveness relies on:

• Biocompatibility Standards: Compliance with the "Tripartite Biocompatibility Guidance for Medical Devices."
• Engineering Standards: Meeting the device's design specifications for dimensions, material integrity, and functionality (e.g., balloon inflation properties).
• Good Manufacturing Practices (GMPs): Adherence to quality system requirements during testing.

There is no "ground truth" derived from expert consensus, pathology, or outcomes data in the context of diagnostic interpretation, as this is an interventional device.

8. Sample Size for the Training Set

This is not applicable. The device is a physical medical instrument, not an AI algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

This is not applicable for the same reason as point 8.
