Colonic Metal Stents

Since 1991 Hanarostent has been developing the market for non-vascular metallic stents while keeping its position as one of the most innovative ranges of stents available in the UK.

In a fast paced and maturing market, Hanarostent has managed to continue to innovate and add unique and clinically superior features to its already premium range. These features add real value to clinical outcome and patient management requirements giving the Hanarostent range a place in every GI and Radiology department.

Features and benefits of Hanarostent

Nitinol Wire
Hanarostent is hand weaved using nitinol (titanium nickel alloy). The nitinol mesh provides flexibility and 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 6-8mm, depending on indication.

Silicone Covering
Hanarostent is available fully covered, partially covered or uncovered depending on the indication.

Lassos
Nylon lassos are attached to each or one end of the covered stents enabling user to accurately reposition or remove with ease.

Gold Markings
A total of twelve gold radiopaque markers are located at distal, proximal and central points of the stent to ensure excellent visualisation and precise positioning when using X-ray.

Delivery Device
The Dolphin Delivery Device enables efficient, accurate and easy stenting. Soft and atraumatic radiopaque olive tips can easily pass through the stenosis.   The flexibility of the 6mm catheter can travel through tortuous anatomy. The ergonomic handle is designed for controlled and accurate stent deployment and positioning.
