Problem

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.

ACUTE DVT

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)

IDEAL TREATMENT

25% of these DVT cases is an Iliofemoral DVT (neccesitating a thrombectomy), of which 50% needs to be stented (0,25M/year)

CHRONIC PTS

After a DVT, 25 % develops a Post Thrombotic Syndrom (PTS) due to a central venous obstruction (15M prevalence)

IDEAL TREATMENT

PTS is treated by anti-coagulation, compression and mobilisation. Stenting is a better alternative to this treatment.

PROBLEM

Current first generation stents still have a failure rate of 15-25%, and patients are often forced to use anti-coagulants life long.

There is a clear need for a new generation venous stent

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

Solution


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.
