A biocompatible filtration catheter configured for placement in the brachiocephalic artery from an approach from an insertion point in a patient's right arm comprising: a shaft having a balloon lumen, proximal end and a distal end with a distal opening, wherein the shaft has a length suitable for reaching the brachiocephalic artery from the insertion point; a proximal port in fluid communication with the balloon lumen and connected to the proximal end of the shaft; an integrated filter element formed from a woven bundle of fibers, such as polymer fibers, or a combination of metal fibers and polymer fibers, formed into a tubular section that replaces a section of a wall of the catheter near the distal end of the shaft, wherein the integrated filter element provides for fluid flow out from the catheter interior; a distal section extending in a distal orientation from the integrated filter element, and having the distal opening, wherein the balloon lumen extends past the integrated filter element from the shaft to the distal section; an occlusive element wherein the occlusive element is a balloon having an extended configuration with a diameter suitable to occlude a human brachiocephalic artery and having an interior in fluid communication with the balloon lumen, the occlusive element being associated with the exterior of the distal section at or near the distal end of the distal section of the catheter, the balloon being able to extend radially outward from the exterior of and around the circumference of the shaft and being positioned between the distal opening and the integrated filter element; and a conduit extending within the shaft from the distal opening through at least the distal section to the integrated filter element to provide fluid communication between the distal opening and the integrated filter element, wherein the filter element is a fully integrated structure having a similar diameter to a first adjacent shaft section at a distal side of the filter element and a second adjacent shaft section at a proximal side of the filter element and wherein the catheter is suitable for guiding into the brachiocephalic artery from the insertion point. a shaft having a balloon lumen, proximal end and a distal end with a distal opening, wherein the shaft has a length suitable for reaching the brachiocephalic artery from the insertion point; a proximal port in fluid communication with the balloon lumen and connected to the proximal end of the shaft; an integrated filter element formed from a woven bundle of fibers, such as polymer fibers, or a combination of metal fibers and polymer fibers, formed into a tubular section that replaces a section of a wall of the catheter near the distal end of the shaft, wherein the integrated filter element provides for fluid flow out from the catheter interior; a distal section extending in a distal orientation from the integrated filter element, and having the distal opening, wherein the balloon lumen extends past the integrated filter element from the shaft to the distal section; an occlusive element wherein the occlusive element is a balloon having an extended configuration with a diameter suitable to occlude a human brachiocephalic artery and having an interior in fluid communication with the balloon lumen, the occlusive element being associated with the exterior of the distal section at or near the distal end of the distal section of the catheter, the balloon being able to extend radially outward from the exterior of and around the circumference of the shaft and being positioned between the distal opening and the integrated filter element; and a conduit extending within the shaft from the distal opening through at least the distal section to the integrated filter element to provide fluid communication between the distal opening and the integrated filter element, wherein the filter element is a fully integrated structure having a similar diameter to a first adjacent shaft section at a distal side of the filter element and a second adjacent shaft section at a proximal side of the filter element and wherein the catheter is suitable for guiding into the brachiocephalic artery from the insertion point.
