In Balloon Based EVAR (BB-EVAR), 2 patented “dogbone” shaped balloons are advanced from both legs, and merged via a special “skirt” to form a single ballon in the form of a temporary aortic vessel, bridging the aorta-iliac tract and at the same time temporarily occluding bllod flow from the aorta and iliac arteries into the sac, similar to clamping in an open surgical procedure.

​

Filling the sac with AneuFix polymer in the same way as described under 'AneuFix - Prophylactic Sac Filling’, results in a perfect cast around the balloons in a short time. Curing of the polymer takes place in 3 min. After deflating and removing the balloons a new aorta-iliac channel is created in a minimal invasive procedure.

 

This BB-EVAR concept can also be used for treating aneurysms higher up in the aorta, where other vessel sidebranches need to be kept open.
