Plato 17 Microcatheter
The Plato 17 Microcatheter is intended for the introduction of therapeutic devices, infusion of diagnostic agents, such as contrast media, and delivery of embolization materials to the peripheral and neuro vasculature systems. The Plato 17 Microcatheter is not intended for use in the coronary vasculature.
Scientia Vascular's Plato® 17 Microcatheter is a single lumen, open-ended catheter designed to be flexible and axially stable, to aid the physician in the accessing of the distal neuro and peripheral vasculature. The Plato® 17 Microcatheter is supplied sterile and is for single use only. The Plato® 17 Microcatheter is supplied in various tip configurations, including straight and pre-shaped (45° and 90°). The microcatheter shaft design includes nitinol, polymers of varying durometer, and an internal liner providing lubricity for therapeutic device, diagnostic agent, and embolization material delivery. The distal exterior section of the catheter shaft is hydrophilic coated to reduce friction during manipulation in vessels. The microcatheter includes two radiopaque tip markers to facilitate fluoroscopic visualization and a clear hub with luer lock and a strain relief.
The microcatheter is provided with a steam shaping mandrel, peel-away introducer, and a ruler. The shaping mandrel, peel-away introducer, and ruler are accessories included to facilitate use of the microcatheter and are not intended to contact the patient's body.

Plato 17 Microcatheter
The Plato 17 Microcatheter is intended for the introduction of embolic coils and infusion of diagnostic agents, such as contrast media, to the peripheral and neuro vasculature systems. The Plato 17 Microcatheter is not intended for use in the coronary vasculature.
Scientia Vascular's Plato® 17 Microcatheter is a single lumen, open-ended catheter designed to be flexible and axially stable, to aid the physician in the accessing of distal vasculature. The Plato 17 Microcatheter is supplied sterile and is for single use only. The Plato 17 Microcatheter is packaged with various tip configurations, including straight and pre-shaped (45° and 90°). The microcatheter shaft design includes nitinol, polymers of varying durometer and an internal liner providing lubricity for intraluminal delivered embolic coils and contrast media: the distal exterior section of the catheter shaft is hydrophilic coated to reduce friction during manipulation in vessels. The working length of the catheter is 160 cm. The microcatheter includes two radiopague tip markers to facilitate fluoroscopic visualization and a clear hub with luer lock and a strain relief. The Plato 17 Microcatheter is compatible with 0.014 inch guidewires or embolic coils.
The microcatheter is provided with a steam shaping mandrel, peel-away introducer and a ruler. The shaping mandrel, peel-away introducer and ruler are accessories included to facilitate use of the microcatheter and are not intended to contact the patient's body.
The Scientia Vascular, LLC's Plato® 17 Microcatheter was evaluated through non-clinical performance tests, including biocompatibility and functional testing, to demonstrate substantial equivalence to the predicate device, the Excelsior™ SL-10 Pre-Shaped Microcatheter (K042568) and reference device Excelsior XT-17 Microcatheter (K142565).

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the specific sample sizes for each functional test performed. However, it mentions "study animals" for some biocompatibility tests (e.g., sensitization, intracutaneous reactivity, acute systemic toxicity, material-mediated pyrogenicity) and "catheter samples" for corrosion resistance. For the Catheter Usability Study, it mentions a "cadaver study." The provenance of the data (country of origin, retrospective/prospective) is not specified.
3. 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)
For the "Catheter Usability Study," it states "Physician evaluation of the microcatheter in a cadaver study." The number of physicians and their specific qualifications are not provided. For other functional and biocompatibility tests, "ground truth" is established by adherence to recognized standards and objective measurements, not necessarily expert consensus in the clinical sense.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The document does not describe any specific adjudication method for establishing ground truth, as most tests are bench-top or animal studies with objective pass/fail criteria or comparisons to predicate devices/standards. For the "Catheter Usability Study" involving physician evaluation, the method of aggregation or adjudication of physician opinions is not detailed.
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 comparative effectiveness study was done as this device is a microcatheter, not an AI-assisted diagnostic tool. Therefore, the concept of human readers improving with AI assistance is not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This refers to a physical medical device (microcatheter), not an algorithm or AI system. Therefore, standalone algorithm performance is not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For biocompatibility tests, the ground truth is based on the biological responses observed in study animals or in vitro tests, evaluated against established scientific principles and standards (ISO 10993-1:2018). For functional tests, the ground truth is based on physical measurements, mechanical performance, and adherence to engineering standards (ISO 80369-7, ISO 80369-20, ISO 10555-1), as well as comparison to the predicate device where applicable. For the usability study, "acceptable use" by physicians in a cadaver study serves as a form of expert assessment.
8. The sample size for the training set
This device is a physical microcatheter, not a machine learning or AI model. Therefore, the concept of a "training set" is not applicable.
9. How the ground truth for the training set was established
As described in point 8, the concept of a "training set" and its associated ground truth is not applicable to this device submission.
