The Sentinel Cerebral Protection System (CPS) is a dual filter cerebral embolic protection device indicated for use during transcatheter aortic valve replacement (TAVR). The device contains 2 independent filters within a single delivery catheter that is delivered via the right radial artery or brachial artery. The larger proximal filter is deployed in the brachiocephalic trunk, and the smaller distal filter is deployed in the left common carotid artery before TAVR. The Sentinel CPS filters and collects debris released during the TAVR procedure.
