CAPTURE WITH CONFIDENCE

Indicated for Carotids and Lower Extremities

The Emboshield NAV6™ Embolic Protection System, which includes BareWire™ Filter Delivery Wires, allows the guide wire to rotate and advance freely, independent of the Emboshield NAV6™ filter.*

The Emboshield NAV6™ EPS is indicated for use as a guide wire and embolic protection system to contain and remove embolic material (thrombus / debris) while performing angioplasty and stenting procedures in carotid arteries and while performing atherectomy, during standalone procedures or together with PTA and/or stenting, in lower extremity arteries. The diameter of the artery at the site of the Filtration Element placement should be between 2.5 and 7.0 mm.1

Embolic Protection Device for both Lower Extremity and Carotid Arteries

Captures Effectively to Minimise Downstream Complications1-3

  • Centered wire design prevents bias against the vessel wall for effective debris capture.*
  • Circumferential nitinol frame maintains optimal wall apposition, even on a bend.*
  • Platinum-tungsten frame coils provide optimal visibility.*
  • Two sizes allow for easy selection and minimal lab inventory.
     

Limits Filter Movement and Maintains Wire Access Through Innovative BareWire™ Design*

  • The unique BareWire™ technology allows the wire to rotate and advance freely, independently of the filter.
  • The filter is designed to stay in place during device delivery.*
  • Continued wire access, after filter is fully retracted, allows for easy delivery of additional therapy.*
     

Navigates Skillfully Through Carotid and Lower Extremity Vasculature*

  • Various types of BareWires™—distal access, workhorse, and support—are designed for various carotid anatomies.
  • They promote navigational success through torturous anatomy and challenging arches.
     

Is Compatible with Various Atherectomy Options4

  • Emboshield NAV6™ EPS and BareWire™ are compatible with a variety of atherectomy types.
  • BareWire™ is available in 190 cm and 315 cm lengths.
     

In carotid procedures, the Emboshield NAV6™ EPS is used during stenting with the Xact™ Carotid Stent System.

Unique Features: Filter and Barewire™ Delivery Wires

Filter

120-µm PORE SIZE

Effectively captures debris while also allowing blood flow

 

HIGH-STRENGTH NYLON FILTER MATERIAL

Is designed to enhance capture efficiency by maintaining wall apposition and protecting the vessel wall from direct contact with the nitinol frame

 

NON-THROMBOGENIC HYDROPHILIC COATING

designed to reduce platelet or protein adhesion

1. BAREWIRE™ TECHNOLOGY

Is a proprietary wire technology that enables guide wire-only access through the lesion and ensures stable filter position

 

2. PROXIMAL MARKER BAND

Includes proprietary radiopaque markers for smooth tracking through tortuous anatomy

 

3. NITINOL FRAME

Is designed for outstanding circumferential wall apposition—even on a bend—and collapses into a low-profile wrap down during filter retrieval

 

4. CENTERED WIRE DESIGN

Prevents filter bias against the vessel wall and allows effective capture in all vessel types

 

5. RADIOPAQUE MARKERS

To convey vessel apposition and deployment status

 

6. PORE-FREE ZONE AT DISTAL TIP

Prevents extrusion of embolic material during blood flow

 

7. DISTAL MARKER BAND

Includes proprietary radiopaque markers for smooth tracking through tortuous anatomy

 

8. BAREWIRE™ 0.019” STEP

Acts as a distal stop for the Filtration Element

DELIVERY WIRES FOR FLEXIBILITY AND SUPPORT

There are three types of BareWire™ delivery wires.

 

Distal Access

 

A soft BareWire™, it provides extra flexibility for successful access through torturous anatomy

 

 

Workhorse

 

Provides optimal flexibility and support for easy access through most anatomies

 

 

Support

 

Is designed to provide additional support for delivery of the filter in challenging arches

 

 

Filter Visibility

The deployment status and the vessel apposition can be visually confirmed because of the device’s radiopaque frame.

 

Fully Deployed

Fully Captured

System Utilisation: Preparation, Delivery and Retrieval

Straightforward Preparation

The streamlined Emboshield NAV6™ EPS prep procedure requires three steps. Refer to the Instructions for Use for additional information.

 

1. Flush in Two Places

At the exit port of the delivery catheter

In the filter, to remove air bubbles

 

2. Pull the Filter into the Delivery Catheter

Pull until the filter is completely inside the delivery catheter, at which point the gold marker is adjacent to the delivery catheter tip

 

3. Check the Gold Marker

Visually check to ensure that the filter is fully loaded into the delivery catheter.

Optimal Outcomes: Emboshield NAV6™ EPS Clinical Data

Embolic Protection Devices can add a layer of protection during endovascular procedures in the lower extremities or carotids. In the lower extremities, downstream complications can be minimised and in the carotids, the stroke rate can be reduced with the use of EPDs.1

Clinical Findings in Brief

Three trials evaluated carotid stenting with the Emboshield NAV6™ EPS and/or previous generation Abbott products.

  • ACT I: Asymptomatic Carotid Trial I
  • CHOICE: Carotid Stenting for High Surgical-Risk Patients; Evaluating Outcomes Through the CollectIon of Clinical Evidence
  • Protect: Protected Carotid Artery Stenting in Patients at High Risk for Carotid Endarterectomy (CEA)
Summary of Clinical Trial Data for EMBOSHIELD NAV6™ Embolic Protection System


 

DS = Death or stroke | DSMI = Death, stroke, or myocardial infarction | CEA = Carotid endarterectomy
