The Sapphire II PRO coronary dilatation catheter is indicated for:
• balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion
• balloon dilatation of a coronary artery occlusion for the treatment of acute myocardial infarction
The Sapphire II PRO coronary dilatation catheter is a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter with a working length of 140cm. The proximal shaft is a PTFE coated stainless steel hypotube. Hydrophilic lubricious coatings are applied to the distal section. The semi-compliant balloons, available in diameters from 1.5-4.0mm and lengths from 10-30mm, can be inflated by injecting dilute contrast media solution through the trailing hub of the catheter. Two radiopaque platinum marker bands are located within the balloon segment (there is only one centrally located marker band for the Ø1.5mm configurations). The catheter is compatible with 5F or larger guiding catheters. The internal lumen of the catheter accepts a standard 0.014 inch PTCA guidewire. The proximal part of the guidewire enters the catheter tip and advances coaxially out the catheter proximal port, thereby allowing both coaxial guidance and rapid exchange of catheters with a single standard length guidewire. Two marked sections are located on the hypotube shaft to indicate catheter position relative to the tip of either a brachial or femoral guiding catheter. The design of this dilatation catheter does not incorporate a lumen for distal dye injections or distal pressure measurements.
The provided text is related to the FDA 510(k) premarket notification for the "Sapphire II PRO Coronary Dilatation Catheter." This document describes the device, its intended use, and indicates that performance tests were conducted. However, it does not contain specific acceptance criteria values or detailed results of a study in the format requested for AI/medical device performance.
The text details the following about the device's testing:
- Performance Data: "Both in vitro performance tests, such as dimensional verification, balloon preparation, deployment, and retraction, balloon rated burst pressure, balloon fatigue, balloon compliance, balloon inflation and deflation time, catheter bond strength, tip pull strength, flexibility and kinking, torque strength, radiopacity, coating integrity, and particulate evaluation, and also biocompatibility tests, such as cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemocompatibility (hemolysis, partial thromboplastin time, platelet and leukocyte counts, complement activation, and in vivo thromboresistance), pyrogenicity, and genotoxicity (bacterial mutagenicity and in vitro mouse lymphoma) were conducted on the Sapphire II PRO coronary dilatation catheter."
- Result: "The test results met all acceptance criteria, were similar to predicate devices, and ensure that the Sapphire II PRO coronary dilatation catheter design and construction are suitable for its intended use as recommended by the Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters (FDA; September 8, 2010)."
Based on the provided text, I cannot complete the table or provide specific answers to most of the numbered questions because the document lacks the detailed information about acceptance criteria values, specific reported device performance values, sample sizes, ground truth establishment, or any mention of AI or MRMC studies.
The questions posed (e.g., sample sizes for training/test sets, expert qualifications, adjudication methods, MRMC studies, standalone performance for AI) are typically relevant for AI/Machine Learning-based medical devices, which is not what the "Sapphire II PRO Coronary Dilatation Catheter" is. This is a physical medical device (a balloon catheter). Therefore, the requested information structure does not directly apply to this type of device and the information is not present in the document.
However, I can extract what is explicitly stated:
- Study Type: The studies conducted were in vitro performance tests and biocompatibility tests. These are standard for physical medical devices and not related to AI.
- Acceptance Criteria Mention: The document states that "The test results met all acceptance criteria," but it does not specify what those criteria are in quantitative terms.
- Ground Truth: For a physical device like a catheter, "ground truth" typically refers to established engineering specifications, material properties, and biological safety standards, rather than expert consensus on diagnostic interpretations or pathology as would be the case for AI. The document implies these were based on "the Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters (FDA; September 8, 2010)."
Therefore, many parts of your request are not applicable or cannot be answered from the given text.
Here's a response based on the absence of the requested AI-specific information and what is available:
The provided document describes the FDA 510(k) premarket notification for the "Sapphire II PRO Coronary Dilatation Catheter," a physical medical device, not an AI or software-as-a-medical-device.

The design of this dilatation catheter does not incorporate a lumen for distal dye injections or distal pressure measurements.
The provided text describes the regulatory submission for the Sapphire Coronary Dilatation Catheter, focusing on demonstrating substantial equivalence to predicate devices rather than proving a specific AI algorithm's performance against acceptance criteria. Therefore, much of the requested information regarding AI-specific criteria, studies, and data provenance is not applicable.
However, I can extract information related to the device's acceptance criteria and the studies performed to demonstrate equivalence.
Here's a breakdown of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance

Pyrogenicity | Met all acceptance criteria |
Acute systemic toxicity | Met all acceptance criteria |
Intracutaneous reactivity | Met all acceptance criteria |
Genotoxicity (bacterial mutagenicity) | Met all acceptance criteria |
Genotoxicity (in vitro mouse lymphoma) | Met all acceptance criteria |
The document also states that the tests "ensure that the Sapphire coronary dilatation catheter design and construction are suitable for its intended use as recommended by the Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters (FDA; September 8, 2010)." This guidance document would contain the specific acceptance criteria.
2. Sample Size Used for the Test Set and Data Provenance
The document describes product performance and biocompatibility tests, which are laboratory or in vitro studies, not typically involving "test sets" in the context of AI algorithms or clinical trials. Therefore:
- Sample size for the test set: Not applicable in the context of clinical or AI performance. The number of physical units or samples tested for each in vitro or biocompatibility assessment is not specified in this summary.
- Data provenance: Not explicitly stated as country of origin, retrospective, or prospective, as these are not clinical studies. These are laboratory-based validation tests performed internally by the manufacturer (OrbusNeich Medical, Inc.).
