Intricate technical design of the Sniper Balloon Occlusion Microcatheter allows for easy navigation through small complex vascular structures providing enhanced reach to distal target sites.

What is Pressure-Directed Embolization?

The Sniper’s balloon occludes the vessel to alter blood flow-dynamics using pressure-directed embolization. This increases therapeutic agent delivery into target areas while protecting surrounding healthy tissue. 1,2
