Nitinella Plus / Nitinella Plus – B
Personal references
Basic description
The Nitinella Plus is a self-expandable nitinol biliary stent that can be implanted endoscopically or transhepatically and is available as uncovered (Nitinella Plus – B) or partially or fully covered with silicone. Due to the significant radiopaque markers, the product is perfectly visible during implantation and during subsequent X-ray examinations.
Indication
The Nitinella Plus and Nitinella Plus – B are indicated for the palliative treatment of biliary strictures caused by malignant neoplasms.
Features / Benefits
Significant radiopaque markers made of thick-walled Pt / Ir tubes at both ends and in the middle of the stent allow easy visibility of the stent during insertion.
The high flexibility of the stent keeps the lumen open even if placed in anatomical curves. The atraumatic stent ends do not irritate the bile duct wall.
Reinforced braiding at the stent ends – designed to reduce the risk of migration.
The durable silicone covering covers the outer and inner surfaces of the stent and prevents tissue ingrowth.
The delivery system with braided sheath is kink-resistant. Its design allows the stent to be retracted back up to 50% of the stent length.
MRI compatibility – “MR Conditional”, compatible with 1.5 Tesla and 3 Tesla static magnetic field.
Patent protected
Implantation
The stent is delivered sterile compressed in a delivery system. We recommend using a 0.035 ”(0.89 mm) stiff guidewire for the implantation.
