1. A transvascular catheter system for delivery of a medical device to an aortic cardiac valve region of a patient, said system comprising:
a first lumen having a proximal end and a distal end, said first lumen being configured to include a guide wire,
a second lumen that extends parallel to the first lumen between said proximal end and said distal end of said first lumen, and having an orifice at a distal end of said second lumen, wherein
said orifice is positioned proximally with respect to said distal end of said first lumen; and
an expandable embolic protection filter having an unexpanded delivery shape and a non-tubular shape when fully expanded, and wherein said second lumen comprises a delivery unit connected to the expandable embolic protection filter at a connection point arranged at a proximal portion of said expandable embolic protection filter and at least a portion of said expandable embolic protection filter is arranged to extend from said orifice at said distal end of said second lumen so that a distal end of said expandable embolic protection filter is arranged in a direction of an ascending aorta;
the expandable embolic protection filter is configured to cover at least one ostia of side branch vessels in an aortic arch when extended from said orifice of the second lumen;
said distal end of said first lumen is arranged distally of said distal end of said expandable embolic protection filter when fully expanded into said non-tubular shape; and
a medical device delivery system configured to deliver said medical device through said first lumen while said expandable embolic protection filter is fully expanded from said second lumen, and wherein said medical device is a cardiac valve repair or replacement device.
