Intended Use

The Emboshield NAV Embolic Protection System 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. The diameter of the artery at the site of the Filtration Element placement should be between 2.5 and 7.0 mm.

Device Story

The Emboshield NAV6 Embolic Protection System is a temporary percutaneous transluminal filtration system used during carotid artery angioplasty and stenting. The system comprises a BareWire Filter Delivery Wire (stainless steel with PTFE coating and radiopaque tip), an RX Delivery Catheter for deployment, a Filtration Element (nylon membrane with nitinol support), and an RX Retrieval Catheter. The device is operated by a physician in a clinical setting. The Filtration Element is deployed distal to the lesion to capture embolic debris released during the procedure. After the intervention, the Retrieval Catheter is used to collapse and remove the filter containing the captured material. This process prevents embolic material from traveling downstream, potentially reducing the risk of ischemic events during carotid interventions.

Clinical Evidence

Bench testing only. Testing included bioburden, wire movement, coating integrity, particulate testing, and comprehensive biocompatibility assessments (cytotoxicity, hemocompatibility, coagulation, systemic toxicity, irritation, sensitization, and material-mediated pyrogenicity).

Technological Characteristics

Materials: Stainless steel wire, PTFE coating, platinum/nickel radiopaque tips, nylon membrane, nitinol support structure. Dimensions: 0.014" wire, 135-139 cm catheter lengths, 5.0 mm or 7.2 mm filtration element sizes. Principle: Mechanical filtration via percutaneous catheter system. Sterilization: Not specified.

Indications for Use

Indicated for patients undergoing angioplasty and stenting procedures in carotid arteries with vessel diameters between 2.5 and 7.0 mm to contain and remove embolic material (thrombus/debris).

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

{1}------------------------------------------------

## Device Description:

The Emboshield NAV Embolic Protection System (EPS) is a temporary percutaneous transluminal filtration system designed to capture embolic material released during angioplasty and stent procedures within carotid arteries. The system consists of the following components:

#### BareWire Filter Delivery Wire: .

The BareWire Filter Delivery Wire is a 0.014" PTFE coated stainless steel guidewire with a 3 cm platinum/nickel radiopaque distal tip section. Three (3) Bare Wire designs are available as separately packaged items that offer different support levels and wire lengths, 315 cm and 190 cm. A 190cm BareWire Workhorse is supplied with the Emboshield NAV Embolic Protection System.

#### . RX Delivery Catheter:

The RX Delivery Catheter usable length is 135 cm. The crossing profile is either 0.0365" or 0.0415", depending on Filtration Element size. A pull handle is used to deploy the loaded Filtration Element from the pod. Two (2) pairs of indicator bands are provided along the catheter shaft; a proximal pair (90 cm and 100 cm from the catheter tip) to indicate the catheter tip position during advancement through the guide catheter; and a distal pair to indicate the proximity of the RX exit port during catheter retraction. A radiopaque marker band is positioned proximal to the pod.

### · Filtration Element:

The Filtration Element consists of a nylon membrane with an internal radiopaque nitinol support structure . There are two proximal triangular entry ports and multiple 120 micron distal perfusion pores. There is also a proximal and a distal marker band. The Filtration Element is available in two sizes; small (5.0 mm) to treat vessel diameters of 2.5 - 4.8 mm and large (7.2 mm) to treat vessel diameters of 4.0 to 7.0 mm.

#### RX Retrieval Catheter: .

The RX Retrieval Catheter has a usable length of 139 cm and a molded expansile distal tip with a maximum outer diameter of 0.067''. A handle is situated at the proximal end. Two pairs of marker bands indicate the position of the Retrieval Catheter RX guidewire exit port and catheter tip.

### Indication for Use:

The Emboshield NAV® Embolic Protection System 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. The diameter of the artery at the Filtration Element placement should be between 2.5 and 7.0 mm.
