Abstract:
1. A method of filtering a subject's blood to prevent foreign material from traveling into the carotid circulation during an open chest procedure, comprising creating an opening in an aorta prior to cross-clamping the aorta and cardiopulmonary bypass to provide access to the aorta; introducing a first illumination wire through the opening and into the left common carotid artery; introducing a first filter in a collapsed configuration through the opening and over the illumination wire; expanding the first filter in the left common carotid artery to trap foreign material in the left common carotid artery; introducing a second filter in a collapsed configuration through the opening; expanding the second filter in a brachiocephalic trunk to prevent foreign material from traveling into the right common carotid artery; and performing a procedure on the heart of the subject without expanding a filter within the aortic arch.
