The catheters are each inserted into an artery (brachial) and a vein (brachial, ulnar or radial) in the arm through a small puncture or incision. Using fluoroscopy, the catheters are both advanced to the appropriate location for endovascular AV fistula creation (ulnar artery-ulnar vein or radial artery-radial vein). The magnets in the catheters allow them to be precisely aligned while pulling the two adjacent vessels closer together. The venous catheter, which contains the electrode, delivers a burst of RF energy to create a connection between the artery and the vein.
