Impact factor: 130

Like the Niti-S enteral stents these are of a "knitted" construction resulting in excellent conformability without straightening forces. This reduces pressure on the bowel wall and improves coaxial alignment.
In contrast to laser-cut biliary stents these align happily around a tortuous bile duct without risk of impacting in the bile duct wall and making reintervention difficult.
Delivery system for percutaneous biliary stents is really short and easy to handle, but measures 8Fr.
Duodenal and colonic stents come on short 10Fr. systems for non-endoscopic placement. They are nitinol enforced and track easily.
Visibiliy is moderate, expansion force gentle but sustained.

An oesophageal version has just become available.
