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

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.

2. The transvascular catheter system according to claim 1 , wherein said expandable embolic protection filter is arranged to stabilize said distal end of said first lumen when said expandable embolic protection filter is fully expanded out of said second lumen and is in apposition against the surrounding vessel wall.

3. The transvascular catheter system according to claim 1 , further comprising a plurality of radially expandable units arranged for temporarily positioning said first lumen at a desired position in relation to said distal end of said first lumen when said plurality of radially expandable units are in an expanded state.

4. The transvascular catheter system according to claim 3 , configured to deliver the medical device delivery system through the transvascular catheter at a time when the plurality of radially expandable units are in the expanded state.

5. The transvascular catheter system according to claim 1 , wherein said expandable embolic protection filter is an anchor to said first lumen when fully expanded.

6. The transvascular catheter according to claim 1 , wherein said delivery unit is configured to provide an anchoring function for said first lumen.

7. The transvascular catheter according to claim 1 , wherein said connection point is arranged off-center at the expandable embolic protection filter such that said delivery unit is connectable off center to said expandable embolic protection filter.

8. The transvascular catheter according to claim 1 , wherein said non-tubular shape is substantially planar.

9. The transvascular catheter according to claim 1 , wherein the expandable embolic protection filter is configured to cover all ostia of side branch vessels in an aortic arch when fully expanded from said orifice of the second lumen.

10. The transvascular catheter according to claim 1 , wherein a distal end of said expandable embolic protection filter is configured to be in apposition against an inner wall of an ascending aortic arch portion of said aortic arch.
