An assembly of devices intended to provide cerebrovascular embolic protection during carotid artery angioplasty and stenting procedures. It is available in various configurations and typically includes a sheath/catheter(s), intravascular balloon(s), guidewire, and extracorporeal valves/filters. The assembly is introduced into an artery percutaneously and used to produce blockage of blood through balloon inflation, typically at the carotid bifurcation and internal carotid artery to prevent distal embolization by particulate debris/thrombus and allow removal of debris/thrombus by blood filtration or aspiration. This is a single-use device.
