MAKING A DIFFERENCE TO HEALTH

Making a difference to health2 Oesophageal Metal Stents

The Stent...

Features and Benefits:• Nitinol Wire: Hanarostent is hand weaved using ‘high grade’ nitinol (nickel titanium

alloy). The nitinol mesh provides flexibility and excellent radial force. The thermal

shape memory characteristics of nitinol cause the released stent to expand into its

predetermined dimensions at body temperature. The stent is compressed into a small

calibre introducer (10.5fr-24fr), depending on indication.

• Silicone Covering: Hanarostent is available fully covered, partially covered or

uncovered depending on the indication. Typically, fully covered is more suitable for

benign for ease of removal and these stents are CE marked for this indication.

• Lassos: Nylon lassos are attached to at least one end, usually proximal but in some

cases, both ends of the covered stents enabling user to accurately reposition or remove

with ease.

• Gold Markings: A minimum of twelve gold radio-opaque markers are located at

distal, proximal and central points of the stent to ensure excellent visualisation and

precise positioning when using X-ray.

The Delivery Device...

The Delivery Device....

Features and Benefits:• Stent Placement Accuracy: The Hanaro delivery system enables efficient,

accurate and easy stenting. Soft and atraumatic radiopaque olive tips can

easily pass through the stenosis. The flexibility of the delivery catheter can travel

through tortuous anatomy.

• Endoscopic Placement: The ergonomic handle and delivery system is

designed to assist controlled and accurate stent deployment and positioning

under direct vision.

• Fluoroscopic Visualisation: Clear radio-opaque markers on both stent and

delivery system ensures accurate placement under X-Ray conditions.

The outer sheath has to be pulled back against the handle to deliver the stent

without causing patient irritation

• Single silicone layer inside the stent enables it to stay in place longer than conventional

expandable stents

• Outer silicone skirt to enhance patency and resist tumour in-growth

• Larger 24mm shoulders help to reduce migration risk

• Proximal tulip shape shoulder to minimise tissue overgrowth and occlusion

• 12 gold radio-opaque markers provide high visibility under fluoroscopic visualisation -

proximal / central / distal

• Proximal and distal lasso to aid accurate repositioning and retrieval

ECN Asymmetric Fully Covered Upper OesophagusIndication: For application in palliative treatment of a benign stricture in the

oesophageal lumen and / or benign fistula in the oesophagus. Has a CE mark

for benign indications. Can be safely removed within 6 weeks of placement.
