1. A method for transvascularly delivering a medical device to a cardiac valve of a patient, said method comprising:

  • introducing a catheter in a relaxed state into said vascular system, said catheter comprising an elongate sheath having a first lumen a second lumen that extends coaxially with said first lumen along a portion of said elongate sheath between a proximal end of said elongate sheath and a distal end of said elongate sheath;

    navigating said distal end of said elongate sheath through said vascular system to a site of said cardiac valve;

    covering ostia of the side branch vessels in the aortic arch by expanding an embolic protection unit from said second lumen and thereby stabilizing the distal portion of said catheter at the site of said cardiac valve;

    said embolic protection unit comprising an embolic filter that expands to a substantially planar shape; and

    delivering a medical device through the first lumen of said elongate sheath to said site of said heart valve while said embolic protection unit covers said ostia, captures or deflects embolic material, and allows blood to flow from the aortic arch into the side branch vessels.
