A system, apparatus, and method of using the same are disclosed for carrying out a transvascular procedure such as a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure using energy to create a tract between the hepatic vein and the portal vein. The present invention provides a method using a flexible radiofrequency (RF) catheter having a lumen therethrough. The method involves the steps of advancing the flexible RF catheter into a first vessel; advancing a guiding sheath overtop of the flexible RF catheter; steering the guiding sheath to direct a distal tip of the RF catheter towards a second vessel; and, delivering RF energy via the flexible RF catheter, forming a tract from the first vessel and entering the second vessel.
