A balloon-expandable shunt is disclosed for shunting a vessel which has a graft with two ends and is coupled with or to at least one expandable support element at or near at least one of its ends. The shunt is bifurcated at an aperture that leads to a side-channel and which has a closed configuration and an open configuration such that when the aperture is in the closed configuration it defines a clot-resistant inner graft surface and when the aperture is in the open configuration it is configured to provide access to the shunt for a balloon that actuates the expandable support element. A balloon configured for actuating the shunt is also disclosed. A kit is also disclosed, which has a bifurcated graft that has at least one expandable support element and a balloon for actuating the at least one expandable support element.
