Systems and methods for protecting the cerebral vasculature

An embolic protection system for isolating the cerebral vasculature, the system comprising:

• an elongate outer sheath, having a proximal end and a distal end;
• an inner member extending through a lumen of the outer sheath;
• a distal anchoring mechanism coupled to a distal end region of the inner member;
• a proximal filter membrane carried between the inner member and the outer sheath, the proximal filter membrane configured to extend from the left subclavian artery to the brachiocephalic artery;
• a proximal bond tube coupled to a proximal filter bag termination of the proximal filter membrane;
• an aortic support hoop coupled to the proximal filter membrane and configured to seal the proximal filter membrane against the wall of the aorta;
• a handle including a first actuation mechanism coupled to a proximal end of the inner member and a second actuation mechanism coupled to the proximal end of the outer sheath;
• and
• an aortic support hoop connector extending from a proximal end of the aortic support hoop to the proximal bond tube.

• an inner member extending through a lumen of the outer sheath;
• a distal filter assembly coupled to a distal end region of the inner member, the distal filter assembly including a self-expanding frame and a distal filter membrane coupled to the self-expanding frame;
• a proximal filter membrane carried between the inner member and the outer sheath, the proximal filter membrane configured to extend from the left subclavian artery to the brachiocephalic artery;
• an aortic support hoop coupled to the proximal filter membrane and configured to seal the proximal filter membrane against the wall of the aorta;
• a proximal bond tube coupled to a proximal filter bag termination of the proximal filter membrane;
• an aortic support hoop connector coupled to and extending between a proximal end of the aortic support hoop and the proximal bond tube;
• a delivery wire coupled to and extending proximally from the proximal bond tube;
• and
• a handle including a first actuation mechanism coupled to a proximal end of the inner member, a second actuation mechanism coupled to the proximal end of the outer sheath, and a third actuation mechanism coupled to a proximal end of the delivery wire.
