Abstract
A system is configured for treating an artery. The system includes an outer delivery sheath configured to be delivered to a vascular location in communication with an aortic arch, and an inner catheter defining an inner lumen. An outer lumen is formed between an outer wall of the inner catheter and an inner wall of the outer delivery sheath and a filter is positioned at a distal end of the inner catheter. An extracorporeal shunt is configured to receive blood flow from the inner lumen and a filter is coupled to the shunt.

- a filter positioned at a distal end of the inner catheter, the filter configured to guide debris from a blood vessel into the inner lumen of the inner catheter via blood flow into the filter;
- an extracorporeal shunt configured to receive blood flow from the inner lumen;
- and
- a filter coupled to the shunt.
