The Mcdtronic Interceptor® PLUS Coronary Filter System is intended for use in saphenous vein bypass grafts, with a reference vessel diameter between 2.5 mm and 5.25mm, in conjunction with percutaneous transluminal coronary intervention (PTCI) for embolic particulate capture. The Interceptor® PLUS Coronary Filter System is intended for temporary use in conjunction with other therapeutic devices and is intended to be removed at the completion of the interventional procedure.
The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid, or peripheral vasculature
The Interceptor® PLUS Coronary Filter System (the Device) consists of six components; an 180cm extendable Steerable Vascular Filter, an Actuator Handle, a Torque Handle, a Guidewire Introducer, Peel Away Introducer and a RX Facilitator Catheter . The Steerable Vascular Filter is comprised of a radiopaque nitinol filter mounted near the distal tip of a steerable 0.014 inch nitinol hypotube guidewire. The guidewire extends 3.5cm beyond the distal end of the filter in the collapsed state to facilitate distal tracking and steering through tortuous vessels and tight lesions. The proximal end of the steerable vascular filter contains four large openings (Approximately 1400 microns for the 3.5mm filter, >1500 microns for the 4.5mm filter size and >1800 microns for the 5.5mm filter size) that allow embolic particulate to enter the filter.
In addition to the Interceptor® PLUS Coronary Filter System, there is an optional Angled RX Facilitator Catheter when an alternative tip configuration is desired for filter withdrawal.
The Medtronic Interceptor® PLUS Coronary Filter System's acceptance criteria and the study proving its performance are detailed below:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Non-Inferiority Margin) | Reported Device Performance (MACE Rate Difference) | Result |
---|---|---|
Delta of 4.5% (non-inferiority margin for MACE) | Upper 95% CI of the difference: 4.0% | Met |
2. Sample Size and Data Provenance
- Test Set Sample Size:
- Original Analysis: 800 saphenous vein graft patients total (501 in Treatment arm, 247 in Control arm).
- Adjusted Analysis (due to missing CK-MB data):
- Interceptor PLUS (Treatment arm): 139 patients
- Control arm: 82 patients
- Additional data for estimating non-Q wave MI: 158 patients from SAFER study (GuardWire arm) and 178 patients from Amethyst study (Control arm) with non-missing CK-MB.
- Data Provenance: The study was a randomized clinical trial, implying prospective data collection. The document does not specify the country of origin, but given the FDA submission, it's likely a multi-center trial with sites possibly in the US.
3. Number of Experts and Qualifications for Ground Truth
The document does not provide information about the number of experts or their qualifications used to establish the ground truth for the test set. The ground truth (MACE) appears to be derived from clinical outcomes and laboratory results (CK-MB levels) which are typically assessed by physicians and laboratory personnel, rather than explicitly stated "experts" creating a ground truth set for an AI model.
4. Adjudication Method for the Test Set
The document does not explicitly describe an adjudication method for the test set in the context of expert review. The primary endpoint, Major Adverse Cardiac Events (MACE), is a composite clinical outcome determined by predefined criteria (death, Q-wave or non-Q wave MI, emergent CABG, target vessel revascularization). The assessment of these components would follow standard clinical practice and laboratory interpretations, rather than a specific adjudication process for a test set in the way one would for an imaging AI study.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. This study is a clinical trial assessing the effectiveness of a medical device (filter system) in human patients, not a study evaluating human readers' performance with or without AI assistance. Therefore, an MRMC comparative effectiveness study was not conducted, and no effect size for human readers' improvement with AI is reported.
6. Standalone (Algorithm Only) Performance Study
Not applicable. The Interceptor® PLUS Coronary Filter System is a physical medical device (embolic protection filter), not an algorithm or AI model. Therefore, a standalone (algorithm only) performance study was not conducted. The study evaluated the device's performance in preventing adverse cardiac events in patients.
7. Type of Ground Truth Used
The ground truth used was clinical outcomes data, specifically Major Adverse Cardiac Events (MACE), which is a composite endpoint defined by:
- Death
- Q-wave or non-Q wave MI (Myocardial Infarction), assessed via CK-MB results
- Emergent Coronary Artery Bypass Surgery (CABG)
- Target Vessel Revascularization (TVR) within 30 days.
8. Sample Size for the Training Set
Not applicable. This is a study of a physical medical device in a clinical trial, not an AI model. Therefore, there is no "training set" in the context of machine learning.
9. How Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for an AI model.

The Proxis System is indicated for use as a proximal embolic protection system to prevent distal release of and to aspirate embolic material (thrombus/debris) in saphenous vein coronary bypass graft(s) (3.0 mm - 5.0 mm) during percutaneous transluminal coronary angioplasty and/or stenting procedures.
The Proxis System is also indicated to control the flow of fluids and aid in the removal of fresh, soft emboli and thrombi in the coronary and peripheral vasculature.
The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction. The device is not intended to be used as a thrombectomy system.
The Proxis System (Proxis Embolic Protection System) is a proximal embolic protection system used in conjunction with other interventional devices. The Proxis System protects the patient from distal embolization by preventing antegrade flow of emboli release during an interventional procedure and then removing it from the vessel. The Proxis System consists of an Evacuation Sheath Catheter (Proxis Catheter), Inflation device, Aspiration syringe, Lip Seal and Strainer basket.
In addition, an optional accessory called the Proxis Infusion Catheter (packaged separately) may be used with Proxis System.
In the stagnant flow, the guide wire is advanced across the lesion site and the interventional device is tracked over the guide wire. Upon completion of the interventional device procedure, fluid and particles from the procedure may be aspirated using the aspiration syringe. If there is insufficient venous or collateral flow, the Proxis Infusion Catheter (optional accessory) may be used to deliver saline distal to the treatment site while simultaneously applying vacuum to aspirate fluid and particles from the treatment site.

The TriActiv FX® Embolic Protection System is indicated for use in conjunction with percutaneous coronary intervention (PCI), using a 7F guide catheter (without side holes), of diseased saphenous vein coronary bypass grafts ranging from 3.0mm to 5.0m in diameter. The TriActiv FX® Embolic Protection System is intended to protect the distal coronary vasculature by trapping and extracting thrombotic and atheromatous debris liberated during PCI.
The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid, or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction.
The TriActiv FX® Embolic Protection System is a temporary balloon occlusion embolic protection device used during percutaneous coronary intervention of diseased saphenous vein grafts ranging from 3.0mm to 5.0mm in diameter. The device is comprised of four principal components: ShieldWire™ Balloon Guidewire ("balloon guidewire), ShieldWire™ Inflator ("inflator"), FX™ Catheter ("flush catheter"), and AutoStream™ Flow Control ("flow control"). There are also four subcomponents or accessories included in the TriActiv FX® Embolic Protection the Split Tube Introducer, Shieldwire™ Guidewire Plug and Installer, System: TriActiv® Flow Control Power Supply and TriActiv® Tuohy. All TriActiv FX® Embolic Protection System components are supplied sterile and for single use only with exception of the TriActiv® Flow Control Power Supply which is non-sterile and reusable.
The balloon guidewire is advanced through the hospital-supplied 7F guide catheter (without sideholes) prior to percutaneous coronary intervention of a saphenous vein araft (SVG) and positioned just past the target lesion. The balloon is inflated with a medical grade carbon dioxide gas blend, creating a protected space between the quide catheter and the balloon. Once the balloon is inflated and vessel occlusion is confirmed, PTCA and/or stenting can be performed over the balloon guidewire. Immediately after intervention, the flush catheter is loaded on the balloon guidewire and advanced into the graft. With the flush catheter positioned just proximal to the balloon, the flow control delivers saline through the flush catheter to gently wash the vessel and remove any debris generated during the intervention through the guide catheter into a collection bag. The TriActiv FX® Embolic Protection System has been designed to extract at a greater rate than it infuses to prevent aortic embolization. Once the physician is satisfied with the amount of debris removed from the vessel, the protection balloon is deflated and the device is removed.
Here's a breakdown of the acceptance criteria and the study details for the TriActiv FX® Embolic Protection System, based on the provided 510(k) summary:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria for the TriActiv FX® Embolic Protection System were primarily established through a non-inferiority comparison to existing predicate devices (Medtronic Guardwire® or Boston Scientific Filterwire EX™).

The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction.
The Proxis System is a proximal embolic protection system used in conjunction with other interventional devices. The Proxis System protects the patient from distal embolization by preventing antegrade flow of emboli release during an interventional procedure and then removing it from the vessel. The Proxis System consists of an Evacuation Sheath Catheter compatible with 7F or larger guide catheters, Inflation device, Aspiration syringe, Lip Seal and Strainer basket. In addition, an optional accessory called the Proxis Infusion Catheter (packaged separately, K023548) may be used with Proxis System.
The Proxis catheter is loaded onto the guide wire and tracked down to the distal portion of the guide catheter and proximal to the lesion site. To minimize the occlusion time, the interventional devices are advanced through the Proxis catheter and positioned near the distal tip. When the sealing balloon is inflated, antegrade flow of the fluid in the target vessel is prevented. To minimize the release of embolic material, stagnation of flow is accomplished before any devices touch or cross- the lesion(s).
In the stagnant flow, the guide wire is advanced across the lesion site and the interventional device is tracked over the guide wire. After the treatment, fluid and particles from the procedure are evacuated using the aspiration syringe.

The Proxis System is also indicated to control the flow of fluids and aid in the removal of fresh, soft emboli and thrombi in the coronary and peripheral vasculature.
The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction.
The Proxis Embolic Protection System is used in conjunction with other percutaneous transluminal coronary angioplasty devices (PTCA). It is compatible with 8F guide catheters. The Proxis System protects the patient from distal embolization by preventing antegrade flow of emboli released during a PTCA and then removing it from the vessel. The Proxis System consists of an Evacuation Sheath Catheter, Accessory Pack (contains an inflation system, evacuation syringe and double y-adaptor) and an optional additional accessory called the Proxis Infusion Catheter (packaged separately).
The Evacuation Sheath Catheter is loaded into the hemostasis valve and tracked down to the distal portion of the guide catheter. The Evacuation Sheath lines the inner lumen of the distal end of the guide catheter. When the sealing balloons are inflated, the proximal balloon seals against the guide catheter wall and the distal balloon seals against the blood vessel wall and the antegrade flow of the fluid in the target vessel is stopped. The stagnation of flow is accomplished before any devices touch or cross the lesion(s). This minimizes the distal release of embolic material.
Interventional devices are passed through the evacuation sheath to the treatment site and the procedure is performed in stagnant fluid. After the procedure, fluid and particles from the procedure are evacuated using the Evacuation Syringe. The Proxis Infusion Catheter may be used to augment the retrograde flow during the evacuation by infusing saline distal to the treatment site while simultaneously applying vacuum to evacuate fluid and particles from the treatment site.
This document describes the Proxis System, an embolic protection device, and the study supporting its expanded indications. Here's an analysis of the acceptance criteria and the study details:
1. Table of Acceptance Criteria and Reported Device Performance:
The document describes the "Proximal Trial" which assessed the safety and effectiveness of the Proxis System for embolic protection. The primary acceptance criterion appears to be non-inferiority in the 30-day Major Adverse Cardiac Event (MACE) rate compared to existing distal protection devices.

The 510(k) summary focuses on demonstrating substantial equivalence to a predicate device (SpideRX Embolic Protection Device K053195) based on the device description and intended use, particularly the modification to reflect compatibility with drug-eluting stents.
Therefore, I cannot provide the requested table and study details as they are not present in the input text.
To directly answer your numbered points based on the provided text's limitations:
- A table of acceptance criteria and the reported device performance: Not provided in the text.
- Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not provided in the text.
- 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): Not provided in the text.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not provided in the text.
- 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 relevant to this device, as it is a physical medical device (embolic protection system), not an AI-assisted diagnostic tool. No such study information is provided.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not relevant, as this is not an algorithm or AI device. No such study information is provided.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not provided in the text. The 510(k) process for this type of device typically relies on bench testing, animal studies, and clinical data showing safety and effectiveness comparable to a predicate, but specifics are not in this summary.
- The sample size for the training set: Not applicable/not provided. This is a physical device, not a machine learning model.
- How the ground truth for the training set was established: Not applicable/not provided. This is a physical device, not a machine learning model.

The TriActiv FX® Embolic Protection System is indicated for use in conjunction with percutaneous coronary intervention (PCI), using a 7F guide catheter (without side holes), of diseased saphenous vein coronary bypass grafts ranging from 3.0mm to 5.0m in diameter. The TriActiv FX® Embolic Protection System is intended to protect the distal coronary vasculature by trapping and extracting thrombotic and atheromatous debris liberated during PCI.
The safety and effectiveness of this device as an embolic protection system has not been established in the cerebral, carotid, or peripheral vasculature; native coronary arteries; or for treatment of patients with acute myocardial infarction.
The TriActiv FX® Embolic Protection System is a temporary balloon occlusion embolic protection device used during percutaneous coronary intervention of diseased saphenous vein grafts ranging from 3.0mm to 5.0mm in diameter. The device is comprised of four principal components: ShieldWire™ Balloon Guidewire ("balloon guidewire), ShieldWire™ Inflator ("inflator"), FX™ Catheter ("flush catheter"), and AutoStream™ Flow Control ("flow control"). There are also four subcomponents or accessories included in the TriActiv FX® Embolic Protection System: the Split Tube Introducer, Shieldwire™ Guidewire Plug and Installer, TriActiv® Flow Control Power Supply and TriActiv® Tuohy. All TriActiv FX® Embolic Protection System components are supplied sterile and for single use only with exception of the TriActiv® Flow Control Power Supply which is non-sterile and reusable.
The provided text describes the TriActiv FX® Embolic Protection System and its clinical evaluation, but it does not include a table of acceptance criteria or explicitly state acceptance criteria for device performance. It focuses on demonstrating non-inferiority to a predicate device based on clinical outcomes.
However, based on the clinical study results presented, we can infer what the implicit performance goals or "acceptance criteria" likely were, particularly in relation to the predicate device.
Here's an attempt to structure the information based on your request, inferring where explicit details are missing:
1. Table of Acceptance Criteria and Reported Device Performance
Since explicit acceptance criteria are not presented in a table in the submission, the table below infers the performance goals based on the non-inferiority study results compared to the predicate. The "Acceptance Criteria" here are derived from the need to demonstrate non-inferiority to the Active Control Arm of the PRIDE Trial (using Guardwire® Plus System or FilterWire® EX System).
Performance Metric | Acceptance Criteria (Implied for Non-Inferiority) | Reported Device Performance (ASPIRE Enrollment Phase) | Did the Device Meet Criteria? |
---|---|---|---|
Major Adverse Cardiac Events (MACE) to 30 days | Non-inferior to predicate (Active Control Arm MACE rate: 10.1%) | 3.2% (3/93) | Yes (p |
