A duet stent deployment system is used in a transjugular intrahepatic portosystemic shunt procedure. The device has a versatility of adjusting to a patient's anatomy in vivo. The system includes exactly two self expanding stents mounted on an inner catheter and covered by an outer sheath that is moved among a pre-deployment configuration, a first deployment configuration and a second deployment configuration to position the stents in an overlapping configuration from the portal vein, through a shunt and into the hepatic vein, and terminating at the junction with the vena cava.
