The Plato MICROCATH 27B Microcatheter is intended for the introduction of interventional devices and infusion of diagnostic or therapeutic agents to the peripheral system. The cather is not intended for use in cither the coronary or neuro vasculature.
The Plato MICROCATH® 27B Microcatheter is a single lumen microcatheter constructed with a flexible polymer shaft of varying stiffness to aide in accessing vasculature. The catheter is designed to be used with a guide catheter and a steerable guidewire for accessing the vasculature. The proximal end of the catheter has a diameter of 3.4F, tapering to a distal OD of 3.2F, which can be inserted into a 5F guide catheter. The inner diameter is constant throughout the shaft length and accommodates up to a 0.025" guidewire. The catheter is 150 cm in length with a straight tip configuration which can be steam-shaped to the doctor's preferred shape. A steam shaping mandrel is included in the packaging. The microcatheter has hydrophilic coating on the outer distal shaft to reduce friction during manipulation in vessels and has one radiopaque tip marker to facilitate fluoroscopic visualization.
The provided document describes the FDA 510(k) summary for the Plato MICROCATH® 27B Microcatheter, focusing on demonstrating substantial equivalence to predicate devices, not on proving effectiveness for a new diagnostic or interventional AI device. Therefore, the traditional acceptance criteria, study design parameters, and concepts like 'human readers improve with AI' are not applicable to this submission.
Instead, the document details performance data collected from non-clinical testing to show that the new microcatheter is as safe and effective as existing, legally marketed predicate devices. The acceptance criteria essentially derive from established standards for medical devices and comparisons to the predicate devices.
Here's an adaptation of your requested table and information, tailored to the context of this medical device submission:

2. Sample Size Used for the Test Set and Data Provenance
This document primarily reports on non-clinical bench and lab testing, and some limited biological/simulated use testing. The "test set" here refers to the number of devices or samples tested for each specific non-clinical performance attribute.
- Sample Sizes: Not explicitly stated for each test, but implied by the nature of bench testing where multiple samples are typically used to ensure reliability. For example, "all catheters" met specifications implies multiple catheters were tested. For animal studies (thrombogenicity) and cadaver studies, the sample size would be small (e.g., number of dogs, cadavers). For Radiopacity and Simulated Use, "physicians," plural, suggests more than one device per observer.
- Data Provenance: The data is primarily from bench-top laboratory testing and in vitro studies, in accordance with ISO and ASTM standards. Some tests involve animal models (e.g., thrombogenicity in dogs) and human cadavers. The context implies these studies were conducted by the manufacturer or their contracted labs. No specific country of origin for the data is mentioned, but the submission is to the U.S. FDA, and the company is US-based. This is all prospective testing, specifically designed to demonstrate compliance for the 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- Experts: The document mentions "physicians" evaluated radiopacity and participated in cadaver testing. For simulated use, "physicians" also provided Likert scores.
- Number: Not explicitly stated how many physicians were involved in these evaluations. The plural "physicians" indicates more than one.
- Qualifications: Not explicitly stated in terms of years of experience or specific subspecialty (e.g., interventional radiologist), but given the context of medical device evaluation, it is implied that these are qualified medical professionals with expertise relevant to microcatheters and their use.
4. Adjudication Method for the Test Set
- Adjudication Method: Not explicitly detailed. For tests involving "physicians" (Radiopacity, Simulated Use, Cadaver Testing), it is stated that comparisons were made or scores obtained. The document does not specify if there was a formal adjudication process (e.g., 2+1, 3+1), rather it presents the aggregate findings or an overall determination of "comparable" or "acceptable."
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
- No, an MRMC comparative effectiveness study was not done. This type of study (often used for diagnostic imaging AI) is not applicable to a premarket notification for a physical medical device like a microcatheter. The comparison is primarily against established performance standards and a predicate device's existing characteristics. The "simulated use" and "cadaver testing" involve human readers/users (physicians) providing feedback, but this is to assess usability and performance in a simulated environment, not an MRMC study comparing AI with and without human assistance.
- Effect Size of Human readers with/without AI: Not applicable, as this is not an AI device.
6. If a Standalone Study (Algorithm Only Without Human-in-the-Loop Performance) Was Done
- Not applicable. This submission is for a physical medical device (microcatheter), not an algorithm or AI product. The performance evaluations are intrinsic to the device itself and its interaction with biological and simulated environments.
7. The Type of Ground Truth Used
The concept of "ground truth" as it applies to diagnostic or AI studies is not directly applicable here. Instead, the basis for comparison and acceptance is:
- Established Industry Standards: ISO 10993 (biocompatibility), ISO 10555 (intravascular catheters), ASTM standards.
- FDA Guidance: FDA guidance for Short-Term and Long-Term Intravascular Catheters, FDA Special Controls Document for PTCA Catheters.
- Predicate Device Performance: Direct comparison to the ev3 Marksman™ Catheter (K111490, K091559) and the Scientia Vascular, LLC Plato MICROCATH 27 (K121734). The goal is to demonstrate that the new device is "substantially equivalent" in safety and effectiveness.
- Expert Observational Consensus: For aspects like radiopacity and simulated use feedback from physicians.
8. The Sample Size for the Training Set
- Not applicable. This is not a machine learning or AI device, so there is no "training set." The device design and materials are based on engineering principles and prior device knowledge.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. As there is no training set for an AI model, this question does not apply. The "ground truth" for the device's design and expected performance comes from established engineering principles, regulatory standards, and the performance characteristics of predicate devices.

- The Plato MICROCATH® 27B Microcatheter is a single lumen Device Description: microcatheter constructed with a flexible polymer shaft of varying stiffness to aide in accessing vasculature. The catheter is designed to be used with a guide catheter and a steerable guidewire for accessing the vasculature. The proximal end of the catheter has a diameter of 3.4F, tapering to a distal OD of 3.2F, which can be inserted into a 5F guide catheter. The inner diameter is constant throughout the shaft length and accommodates up to a 0.025" guidewire. The catheter is 150 cm in length with a straight tip configuration which can be steam-shaped to the doctor's preferred shape. A steam shaping mandrel is included in the packaging. The microcatheter has hydrophilic coating on the outer distal shaft to
{5}------------------------------------------------
reduce friction during manipulation in vessels and has one radiopaque tip marker to facilitate fluoroscopic visualization.
Indications for Use: The Plato MICROCATH 27B Microcatheter is intended for the introduction of interventional devices and infusion of diagnostic or therapeutic agents to the peripheral system. The catheter is not intended for use in either the coronary or neuro vasculature.
The indications for use are identical to those of the ev3 Marksman Catheter, with the exception that the Marksman Catheter is also indicated for neurovascular and coronary use. The MICROCATH 27B has not been evaluated for these indications. This difference does not affect the safety and effectiveness of the device for its intended application in the peripheral vasculature.
Technological Characteristics:
The Plato MICROCATH 27B Microcatheter is a single lumen, variable stiffness microcatheter designed to provide increased flexibility for accessing the vasculature. The proximal end of the catheter incorporates a polycarbonate Luer adapter to facilitate the attachment of accessories. The distal end has a polymeric skeletal support for improved distal navigation. The device is compatible with 5 F or larger guiding catheters and can be advanced over guidewires up to 0.025" in diameter. The distal shaft has a hydrophilic coating for lubricity and is shapeable.
The technological characteristics are comparable to the predicate device, the ev3 Marksman Catheter. The Marksman Catheter is a single lumen, variable stiffness catheter designed to be introduced over a steerable guidewire into the vasculature. The proximal end of the catheter incorporates a standard Luer adapter to facilitate the attachment of accessories. The distal end has a coiled support structure and the device is compatible with 4 F or larger guiding catheters and can accommodate guidewires up to 0.021" in diameter. The Marksman catheter has an embedded braid to impart strength and stiffness to the proximal end and a coiled structure in the distal end. The Plato MICROCATH 27B Microcatheter uses and embedded stainless steel braid on the proximal end and uses a polymeric skeletal support in the distal end to support the lumen and prevent collapse in tortuous vessels. The outer surface of the distal end of the catheter is coated to increase lubricity, and the catheter is shapeable. The technological differences between the Plato MICROCATH 27B Microcatheter and the ev3 Marksman Catheter do not raise new questions of safety or efficacy.

{6}------------------------------------------------
The technological differences between the Plato MICROCATH 27B and the marketed Plato MICROCATH 27 models include 1) the rigid hypotube at the proximal end has been replace with a braided coil to increase flexibility, 2) the outer diameter has been reduced to allow the microcatheter to be advanced into small vasculature, 3) the distal end of the catheter has been modified with a replacement thermoplastic elastomer, a polymer microstructure and alternate lubricious coating to improved usability, 4) a polycarbonate hub replaces the polymethylpentene hub based on physician preferences and, 5) a platinum marker replaces the platinum marker coil. These technological differences do not raise new questions of safety or efficacy.
