The Advocate PTA Catheter is intended for balloon dilation of the illac, femoral, popliteal, renal arteries and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.

The Advocate PTA Catheter consists of two lumens, a compatible guidewire lumen (0.014", 0.018" or 0.035") extending from guide wire port in the manifold to the catheter distal tip, and an inflation lumen extending from the proximal inflation port in the manifold to the balloon interior. There are various size balloons in the product matrix, ranging from 2.0-12.0mm in diameter and 15-300mm in length. The catheter has two radiopaque marker bands that facilitate visibility and location during the placement and inflation of the balloon. The catheter is inserted through a 4Fr, 5Fr, 6Fr or 7Fr haemostatic or non haemostatic introducer, depending on the model selected.

The Merit S-MAK XL™ is intended for percutaneous placement of up to a 0.038" (.097mm) guide wire or catheter into the vascular system.

The S-MAK XL TM utilizes a small diameter coaxial introducer/dilator pair and guide wire for placement of larger diameter guide wires into the vasculature system when a small needle stick is preferred. The S-MAK XL TM consists of the following components: One (1) 4F Coaxial Introducer/Dilator Pair (30 cm length) One (1) 21 gauge Introducer Needle One (1) 0.018" (0.46mm) 80cm Nitinol/Palladium Guide Wire

The provided text describes the 510(k) summary for the S-MAK XL™ device. Based on the information available, a study was conducted to demonstrate the device's substantial equivalence to predicate devices, focusing on performance and biocompatibility.

Here's an analysis of the acceptance criteria and the study that proves the device meets them:

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

The document does not explicitly state "acceptance criteria" in a quantified table format for each test. Instead, it lists the types of performance and biocompatibility tests conducted and states that "Passing results were demonstrated on all tests above." We can infer the acceptance criterion for each test was a "passing result" according to the specified international standards and guidance documents.

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

The document does not explicitly state the sample sizes used for each performance and biocompatibility test set. The provenance of the data is implied to be from laboratory testing conducted according to the listed international standards (e.g., ISO, ASTM, USP). There is no information about the country of origin of the data or whether it was retrospective or prospective.

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

This information is not applicable to the type of testing performed for the S-MAK XL™. The tests are primarily physical, chemical, and biological evaluations, not requiring expert human interpretation to establish a ground truth in the way medical imaging or diagnostic studies might. The "ground truth" is inherently defined by the technical specifications and standards (e.g., a device either passes a tensile strength test or it doesn't).

4. Adjudication method for the test set

Not applicable. The tests are objective and based on established international standards, not requiring adjudication by multiple experts.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. The S-MAK XL™ is a medical device (vessel dilator/introducer sheath), not an AI-powered diagnostic tool. Therefore, an MRMC comparative effectiveness study involving human readers or AI assistance would not be relevant.

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

Not applicable. The S-MAK XL™ is a physical medical device, not an algorithm or software. Therefore, standalone algorithm performance testing is not relevant.

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

The ground truth for the performance tests and biocompatibility tests is based on adherence to the specified international standards and guidance documents (e.g., ISO, ASTM, USP). For instance, for cytotoxicity, the ground truth is whether the device extract causes a cytotoxic effect within defined parameters. For physical performance, the ground truth is whether the device meets its design specifications (e.g., correct length, ability to insert guide wire).

8. The sample size for the training set

Not applicable. As a physical medical device, the S-MAK XL™ does not involve machine learning algorithms that require a "training set."

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

Not applicable, as there is no training set for this type of device.

The Advocate PTA Catheter is intended for balloon dilation of the iliac, femoral, popliteal, and renal arteries.

The Advocate PTA Catheter consists of two lumens, a compatible guidewire lumen (0.014", 0.018" or 0.035") extending from guide wire port in the manifold to the catheter distal tip, and an inflation lumen extending from the proximal inflation port in the manifold to the balloon interior. There are various size balloons in the product matrix, ranging from 2.0-12.0mm in diameter and 20-300mm in length. The catheter has two radiopaque marker bands that facilitate visibility and location during the placement and inflation of the balloon. The catheter is inserted through a 4Fr, 5Fr, 6Fr or 7Fr haemostatic or non haemostatic introducer, depending on the model selected.

The provided document is a 510(k) premarket notification decision letter from the FDA to Merit Medical Systems, Inc. regarding the Advocate PTA Catheter. It outlines the regulatory classification, intended use, and substantial equivalence to predicate devices.

Crucially, this document is for a physical medical device (a catheter for angioplasty), not a software or AI-based medical device. Therefore, the specific questions related to AI/software performance, such as acceptance criteria, sample sizes for test/training sets, expert ground truth establishment, MRMC studies, and standalone algorithm performance, are not applicable to the information contained within this document.

The document explicitly states: "No Safety or Performance testing is required to establish the safety and efficacy of the subject device." This is because the device is being marketed as substantially equivalent to existing predicate devices (Pirouette 014, 018, and 035) with "no technological differences" and manufactured by the "same Manufacturer who makes the identical device under the Pirouette name." The only difference noted is the naming and labeling of the product.

Therefore, I cannot provide the requested information based on this document. The questions you posed are relevant for AI/software medical devices, which typically require extensive validation studies to demonstrate performance.

Merit Medical guide wires are used to facilitate the placement of devices during diagnostic and interventional procedures.

Merit InQwire® Amplatz Super Stiff Guide Wires are intended to facilitate the placement of devices during diagnostic and interventional procedures. The guide wires consist of a Blue PTFE (Polytetrafluoroethylene) coated flat wire coil, with an inside core wire. The core wire enhances the "Super Stiff" characteristic of the guide wire. The core wire extends the full length of the coil and is welded to the coil at three (3) points; a) the distal end, b) the proximal end and c) a spot weld approx. 22cm from the distal end. These welds are designed to provide integrity and ensure that the guide wire components remain together The outside coil is PTFE coated and this Blue PTFE coating extends from the distal tip of the wire to within 7cm of the proximal tip, which remains uncoated. The Merit InQwire® Amplatz Super Stiff Guide Wires are offered in 0.035-inch and 0.038-inch outer diameter with a 1cm, 3cm, 3.5cm ,4cm, 6cm and 7cm straight and J tip configuration and are available in lengths from 75cm to 260cm. The wires will be provided in a spiral hoop dispenser sized appropriately for the wires diameter and length. The dispenser has a standard flush port luer adapter that accepts any standard luer lock or slip tip syringe to facilitate flushing of the guide wire prior to use. A J-straightener is provided on the dispenser to facilitate the advancement of the wire tip into other devices.

The provided text describes testing conducted for the InQwire Amplatz Super Stiff Guide Wire (K170700) to demonstrate its substantial equivalence to predicate devices, not specifically for a software algorithm.
