A shunt includes a tubular body having first and second legs at a proximal end and a third leg at a distal end. A fluid distensible balloon and cooperating insufflation conduit are carried on the tubular body. The first leg of the tubular body includes a longitudinal slit for receiving the second leg whereby the first and second legs may be positioned substantially coaxial so as to allow easier introduction of the shunt into the blood vessel of a patient. Similarly, the second leg having a longitudinally slit for receiving a portion of the cooperating insufflation conduit and also holding it in a coaxial position. A leader tube with a blunt atraumatic tip is received over the proximal end of the tubular body to further aid in the introduction of the shunt.
