Veins are constantly changing in form and shape and therefore axial and longitudinal flexibility is needed
Due to stifness and straightening of current stents the healing process is hindered and blood flow is suboptimal
Deep Vein Thrombosis (DVT) affects close to 1 million people each year and occurs when a blood clot (thrombus) forms in the deep veins in the body. Between 25 to 60% of these DVT patients suffers from Post Thrombotic Syndrome (PTS) which includes painful swollen legs leading to immobility and other skin issues, decreasing their quality of life significantly.
Deep Vein Thrombosis (DVT) is a blood clot (thrombus) that obstructs one or more of the deep veins in the body, usually in the legs (2M/year)
25% of these DVT cases is an Iliofemoral DVT (neccesitating a thrombectomy), of which 50% needs to be stented (0,25M/year)
After a DVT, 25 % develops a Post Thrombotic Syndrom (PTS) due to a central venous obstruction (15M prevalence)
PTS is treated by anti-coagulation, compression and mobilisation. Stenting is a better alternative to this treatment.
Current first generation stents still have a failure rate of 15-25%, and patients are often forced to use anti-coagulants life long.

Venous Stent B.V. develops the world’s first in length adjustable multi-segmented venous stent: The WStent. This design is based on the fact that in venous stenting it is not necessary to cover the complete endothelial wall as in arteries, but it is just there to prevent the vein from collapsing. The novel segmented design allows for high radial force per segment and high flexibility. This, combined with the adjustable intersegmental distances, leads to less stent material against the vein wall nurturing faster endothelial healing and higher porosity, and therefore reducing the necessity to anticoagulants use in the long run.
WStent is a novel, dedicated and segmental venous stent with a design that allows for major clinical improvement
More flexibility - High radial force - Higher porosity - Better positioning
Better patency rate - Better clinical improvement - Better healing - Better endothelisation - Less anti-coagulation
