This protection device is designed to protect the brain circulation from plaque debris during angioplasty performed before or after stent deployment.
It is characterized by two distinct balloons inflatable through two separate working channels: a distal compliant occlusion balloon, 7mm in diameter, is for flow occlusion while a proximal balloon is a standard angioplasty balloon available in two different sizes: 6 x 20mm and 5 x 15mm fit for dilating the stenotic portion of the stent.
After stent deployment, the guiding catheter is advanced into the stent, the guide-wire is removed and all the system is placed within the stent. Then the occlusion balloon is inflated, distally to the stent, to block the antegrade blood flow.
Once the carotid occlusion has been verified with contrast injection, the angioplasty balloon is inflated at the level of the lesion.
After PTA the working site is cleaned from debris aspirated through the catheter lumen.
Once all blood is removed, the occlusion balloon is deflated and the entire system removed.
