SYSTEMS AND METHODS FOR CREATING ARTERIOVENOUS (AV) A device (110) for creating an arteriovenous (AV) fistula, comprising: a first member comprising a main body (112 having a primary lumen (114) and a secondary lumen (116); a second member comprising a piercing member (48) disposed in said secondary lumen (116), and configured to be moved distally out of said secondary lumen (116), and to cut through tissue while being distally moved; and a third member extending from a distal end of the piercing member (48) and being actuatable to move adjacent first and second blood vessels (118, 120) toward one another is energised to create an elongated communicating aperture (142) in opposing sides of each of the first vessel (118) and the second vessel (120).
