1. A system for treating an aortic valve, comprising:
an arterial access sheath configured to be inserted into an access point in a common carotid artery through a penetration in a neck of a patient, the arterial access sheath having an internal lumen;
wherein the arterial access sheath has a first lumen configured to receive a valve delivery system, the valve delivery system configured to deliver a prosthetic valve into a heart or aorta through the arterial access sheath, the first lumen having a first opening at a proximal end of the arterial access sheath and a second opening at a distal most end of the arterial access sheath;
wherein the arterial access sheath further has a first Y-arm located at a proximal region of the arterial access sheath, the first Y-arm splitting into a flow shunt and into the first opening at the proximal end of the arterial access sheath such that the Y-arm communicates with the flow shunt that is configured to reintroduce blood flow into the carotid artery at a location upstream from the access point into the carotid artery, the flow shunt connected to the first Y-arm of the arterial access sheath at a first end of the shunt and such that the first Y-arm also communicates with the first opening at the proximal end of the arterial access sheath;
a second Y-arm connected to the flow shunt at a second end of the flow shunt wherein the second Y-arm fluidly connects the flow shunt to a second, parallel lumen of the arterial access sheath, the parallel lumen being positioned parallel with at least a portion of the internal lumen of the arterial access sheath such that the arterial access sheath contains two lumens that are simultaneously open, and wherein the second, parallel lumen forms a third opening of the arterial access sheath, the third opening being positioned along the arterial access sheath proximal of the second opening and wherein blood flows out of the third opening solely from the second, parallel lumen, and wherein the internal lumen of the arterial access sheath has a uniform diameter distal of the third opening, and wherein the parallel lumen and the first lumen concurrently provide fixed flow paths and are separated by a fixed wall;
a guidewire sized and shaped to be inserted through the arterial access sheath and across a native aortic valve;
a filter configured to be deployed in an artery via the penetration, the filter being sized and shaped to be deployed within the aortic arch so that all the head and neck vessels are protected by the filter from embolic debris during a valve implantation procedure, wherein the filter has a substantially conical shape when positioned in the aortic arch such that a widened portion of the filter traverses an entire diameter of an ascending portion of the aorta when deployed in the aorta, wherein the filter is positioned substantially on one side of the sheath when deployed; and
a prosthetic valve configured to be inserted through the arterial access sheath and percutaneously deployed at or near the position of the native aortic valve.
