Figure 1 The Proxis Embolic Protection System
Proxis is tracked through the guide catheter and into the target vessel, proximal to the treatment area. The guidewire and interventional device are inserted through Proxis and may be staged proximal to the treatment area before balloon inflation. Balloon inflation suspends blood flow, ensuring stagnation of blood and liberated embolic material during treatment of the lesion. During protection, a static column of contrast verifies adequate sealing and highlights the treatment area to facilitate interventional device placement.
