Device and method for delivery of medical devices to a cardiac valve

A method for transvascularly delivering a medical device to a cardiac valve of a patient, comprising

• introducing a first lumen comprising a proximal end and a distal end;
• passing a guidewire along the first lumen from the proximal end of the first lumen to the distal end of the first lumen;
• introducing a second lumen that extends parallel to the first lumen from the proximal end of the first lumen to the distal end of the first lumen, wherein the second lumen comprises an orifice at a distal end of the second lumen, a delivery unit, and a connection point;
• positioning the orifice proximally with respect to the distal end of the first lumen;
• advancing an expandable embolic protection filter in an unexpanded delivery shape along the second lumen;
• extending the expandable embolic protection filter from the orifice at the distal end of the second lumen;
• fully expanding the expandable embolic protection filter, via the delivery unit and the connection point, to a non-tubular shape;
• arranging the expandable embolic protection filter so that a distal end of the expandable embolic protection filter is in a direction of an ascending aorta;
• covering at least one ostia of side branch vessels in an aortic arch when extending the expandable embolic protection filter from the orifice at the distal end of the second lumen;
• arranging the distal end of the first lumen distally of the distal end of the expandable embolic protection filter when the expandable embolic protection filter is fully expanded into the non-tubular shape;
• and
• delivering the medical device through the first lumen while the expandable embolic protection filter is fully expanded into the non-tubular shape, wherein the medical device is a cardiac valve repair or replacement device.
