The Netherlands
Devices for treatment


Embolic agents such as pushable and detachable coils are being used for a wide range of clinical applications within interventional radiology, such as arterial bleedings and treatment of peripheral aneurysms. Those procedures are relatively costly and time inefficient due to fact that, depending on the case, a large number of coils is needed to successfully achieve an occlusion and stop the bleeding or to fill the aneurysm. Consequently, despite its broad clinical indications in many fields, these coils remain unknown and underutilized in many countries around the world, particularly in low- and middle-income countries.


Therefore, there is a need for an embolic agent that is easy to use and deploy, can be reliably positioned and placed, causes minimal (micro)catheter kickback and is also affordable for lower- and middle-income countries, because the current available coils in western countries are premium priced and these products are too expensive for low- and middle-income countries.


Occlufibre is developing a novel fibre based embolic agent. This one-size fits all solution will be detached on the spot after successful occlusion. This affordable solution leads to higher precision, lower intervention times and better availability of embolic agents in middle- and low-income countries.


The proof of principle for the Occlufibre concept was successfully demonstrated. A follow-up study will be performed in an in vitro model followed by the first in vivo studies.
