The WIRION™ is indicated for use as an embolic protection system to contain and remove embolic material (thrombus/ debris) while performing angioplasty and stenting procedures in carotid arteries.
The diameter of the vessel at the site of filter basket placement should be between 3.5 mm to 6.0 mm. WIRION™ may be used with commercially available 0.014" guide wires.
WIRION™ is a embolic protection System comprised of an independent Filter Unit that can be delivered, locked and deployed on commercially marketed guide wires, according to physician preference, anywhere on the wire. The WIRION™ is a rapid exchange system for single use by a single operator.
Here's a breakdown of the acceptance criteria and the study details for the WIRION™ Embolic Protection System, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document explicitly states that "All tests met their predetermined acceptance criteria," but it does not provide a specific table of these criteria. Instead, it details the observed performance of the primary and secondary endpoints in the clinical study.
| Endpoint Category | Acceptance Criteria (Implied/Performance Goal) | Reported Device Performance |
|---|---|---|
| Primary Endpoint | MACCE rate < 0.0015 (P value vs. historic control) | MACCE rate: 3.3% (P value = 0.0008) |
| Secondary Endpoints (Performance) | High success rate (>95%) for all functions | Device success: 99.2% |
| Clinical success: 97.5% | ||
| Angiographic success: 99.2% | ||
| Procedural success: 98.3% | ||
| Secondary Endpoints (Complications) | Low incidence of complications | Access site complications: 1.7% |
| Neurological events: 4.1% |
Study Details:
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: 120 patients
- Data Provenance: Clinical studies. The text does not explicitly state the country of origin but implies a multicenter study, and it mentions "historic control" which suggests a comparison to existing data from potentially various sources. The study was prospective, open label, and single arm.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document does not provide details on the number or specific qualifications of experts used to establish ground truth for the clinical study. MACCE (Major Adverse Cardiac and Cerebrovascular Events) rates and other clinical endpoints are typically determined by clinical outcomes and adjudicated by study investigators or independent clinical events committees, but the specific structure is not described here.
4. Adjudication Method for the Test Set
The document does not explicitly state the adjudication method (e.g., 2+1, 3+1). Clinical trials typically use independent adjudication committees for primary endpoints like MACCE, but this detail is not provided.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size
No, an MRMC comparative effectiveness study involving human readers with and without AI assistance was not conducted or mentioned. This device is an embolic protection system (a physical medical device), not an AI-powered diagnostic tool.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
No, a standalone algorithm performance study was not done. This is a physical medical device. The performance refers to its function within the human body during a medical procedure, not an algorithm's output.
7. The Type of Ground Truth Used
The ground truth for the clinical study was based on outcomes data (MACCE rates, device success, clinical success, angiographic success, procedural success, complications) observed in human patients during the study.
8. The Sample Size for the Training Set
The document does not mention a "training set" in the context of an algorithm or AI. This is a physical medical device, not a software algorithm that would require a training set. The clinical study described involved 120 patients.
9. How the Ground Truth for the Training Set Was Established
As there is no "training set" for an algorithm mentioned, this question is not applicable. For the clinical study, the ground truth was established by clinical observation and assessment of patient outcomes.

Indication for Use Statement:
The WIRION™ is indicated for use as an embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in carotid arteries.
The diameter of the vessel at the site of filter basket placement should be between 3.5 mm to 6.0 mm. WIRION™ may be used with commercially available 0.014" guide wires.
Technological characteristics and Substantial Equivalence:
A comparison between the WIRION™ Embolic Protection System and its predicates was performed in order to support substantial equivalence determination.
The substantial equivalency was concluded based on the device's intended use, system components, functional characteristics, principle of operation, technological characteristics, sterilization, materials and biocompatibility.
The conclusion of the comparison analysis is that the WIRION™ Embolic Protection System is Substantially Equivalent to the predicate devices.
Performance Testing:
Clinical and non-clinical tests were conducted. The appropriate tests performed in order to determine substantial equivalency were completed.
These include testing in accordance with FDA Guidance for coronary and carotid embolic protection devices - premarket notification submissions (February 15, 2008) and additional tests as determined during WIRION™s V&V activities. All tests met their predetermined acceptance criteria and the device was found substantially equivalent to the predicate devices for its intended use.
Non-clinical Data:
The following tests have been performed:
- a) Embolic Capture Efficiency and Retrieval Ability
- b) Stent Compatibility
- c) Simulated Use
- d) Resistance to filter rupture during removal of a fully loaded filter
- e) Flow Characteristics
- f) Radial Outward Force
- g) Tip Flexibility

The graphic element is composed of two overlapping shapes: a blue, semi-transparent shape on the left and a red shape on the right, both with a dotted pattern. Below the graphic, the word "GARDIA" is written in a bold, blue sans-serif font, and below that, the word "MEDICAL" is written in a smaller, lighter blue font.
- p) Shelf Life/Package Integrity Tests
- q) Biocompatibility according to ISO 10993-1:2009 and FDA Blue Book Memorandum, G95-1.
Animal Data:
Two animal studies were conducted using swine model.
Safety parameters such as vessel injury, thrombus formation, neurological effects, device integrity and hemolysis were evaluated.
Performance parameters including usability, navigation, delivery, placement and retrieval of the system and the ability to capture embolic particles were evaluated as well. The device performed comparably to the predicate device. The animal studies results support the substantial equivalence of the WIRION EPS.
Clinical Data
Clinical data from the WIRION™ was collected from clinical studies and commercial use.
Open label single arm feasibility study aimed at demonstrating the safety and performances of the device used during treatment of carotid artery lesions undergoing stenting was conducted.
The WISE study: Multicenter non-randomized prospective, open label, single arm study with comparison to historic control was conducted on 120 patients.
The primary endpoint was MACCE rate and the secondary endpoint evaluated the device performances.
The data demonstrated that the observed MACCE rate was 3.3% while the MACCE rate of the historic control was 6.3%. The obtained P value was 0.0008, less than the 0.0015 which is the performance goal of the study thus the WIRION system met the primary end point.
Secondary endpoint (performances) included device success, clinical success, access site complications, angiographic and procedural success rate. All functions had high success rate of more than 95%. The endpoints related to incidents and complications, were low resulting in 1.7% and 4.1% as summarized below: Device success: 99.2%; Clinical success: 97.5%; Angiographic success: 99.2%; Procedural success: 98.3%; Access site complications: 1.7%; Neurological events: 4.1%. The device performed well and met all specifications and intended use requirements therefore secondary endpoint was met as well.
Conclusions:
The evaluation of the WIRION™ Embolic Protection System performance tests and biocompatibility studies demonstrated that the device performs as intended and that it is as safe and as effective as the predicate devices.
In light of the above, we believe it is substantially equivalent to the FilterWire EZ™ Embolic Protection System (K063313) and to the AngioGuard RX Emboli Capture Guidewire System (K101651) and that it is appropriate for its intended use.
