Oesophageal 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. Centimetre graduation markings allow precise visual deployment of stent under direct vision.

Asymmetric Fully Covered – Upper Oesophagus

Indication – For application in palliative treatment of oesophageal stricture and/or management of perforations and post-surgical leaks and fistula by malignant and benign tumours. CE mark for benign indications – can be safely removed within 6 weeks of placement.

  • Proximal short shoulder (1cm) to improve patient comfort of stent placed in upper oesophagus
  • Upper lasso positioned inside stent to improve patient comfort
  • Outer silicone flange to enhance patency and resist tumour in-growth
  • Inner silicone covering for smooth passage of food and fluid
  • 12 gold radiopaque markers provide high visibility under fluoroscopic visualisation – proximal/central/distal
  • Proximal and distal lasso to aid accurate repositioning and retrieval

Double Fully Covered – Middle Oesophagus

Indication – Application in palliative treatment of a benign stricture in the oesophageal lumen and/or benign fistula in the oesophagus. CE mark for benign indications – can be safely removed within 8 weeks of placement

  • Triple external silicone covering on shoulders and usable section and one layer inside enables stent to stay in place longer than conventional expandable stents
  • Larger 28mm shoulders help to reduce migration
  • Proximal tulip shape shoulder to prevent tissue overgrowth
  • Inner silicone covering for smooth passage of food and fluid
  • Outer silicone covering blocks the direct contact between mucosa and nitinol wire for easy removal of stent.
  • 12 gold radiopaque markers provide high visibility under fluoroscopic visualisation – proximal/central/distal
  • Proximal and distal lasso to aid accurate repositioning and retrieval

Fully Covered – Middle Oesophagus

Indication – For application in palliative treatment of oesophagus stricture and/or management of perforations and post-surgical leaks and fistula by malignant and benign tumours. CE mark for benign indications – can be safely removed within 6 weeks of placement

  • Tulip shaped shoulders increase radial force and reduce migration
  • No silicone outer covering to help reduce migration; rough surface holds on tissue
  • Inner silicone covering for smooth passage of food and fluid and resist tissue in-growth
  • 12 gold radiopaque markers provide high visibility under fluoroscopic visualisation – proximal/central/distal locations
  • Proximal and distal lasso to aid accurate repositioning and retrieval

Partially Covered – Middle Oesophagus

Indications – For palliative treatment of oesophagus stricture and/or trachea-oesophageal fistula caused by malignant tumours

  • Both end-shoulders have a non-covered segment enabling tissue grab and minimising the risk of migration
  • Tulip shape proximal shoulder is less invasive and decreases granulation and overgrowth
  • Inner silicone covering for smooth passage of food and fluid
  • Outer silicone flange to enhance patency and resist tumour in-growth
  • 12 gold radiopaque markers provide high visibility under fluoroscopic visualisation – proximal/central/distal
  • Proximal and distal lasso to aid accurate repositioning.
