Abstract
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.
Claims (28)
1. A method of performing a TIPS procedure, comprising the steps of:
advancing a flexible radiofrequency catheter into a first vessel, the flexible radiofrequency catheter having a lumen therethrough;
advancing a guiding sheath overtop of the flexible radiofrequency catheter, wherein the guiding sheath includes at least one directional marker visible as a first shape in a side view and as a second shape in a top view, and alignment bands located on an angled tip of the guiding sheath, the alignment bands configured for alignment in a gun-barrel view;
visualizing the guiding sheath and radiofrequency catheter under imaging;
steering the guiding sheath, using the at least one directional marker and the alignment bands, to direct a distal tip of the flexible radiofrequency catheter towards a second vessel; and,
delivering radiofrequency energy using the flexible radiofrequency catheter to form a tract from the first vessel and entering the second vessel.
2. The method of claim 1 , wherein the flexible radiofrequency catheter further comprises at least one electrode positioned at a distal end of the flexible radiofrequency catheter and wherein the at least one electrode is configured to deliver radiofrequency energy.
3. The method of claim 1 , further comprising a step of gaining access to the first vessel using a guidewire and advancing the flexible radiofrequency catheter overtop of the guidewire into the first vessel.
4. The method of claim 1 , further comprising a step of confirming access of the second vessel.
5. The method of claim 4 , wherein the step of confirming access involves aspirating fluid through the lumen of the flexible radiofrequency catheter.
6. The method of claim 4 , wherein the step of confirming access involves injecting a contrast fluid into the second vessel through the lumen of the flexible radiofrequency catheter.
7. The method of claim 4 , wherein the step of confirming access comprises inserting a target into the second vessel and assessing proximity to the target from the flexible radiofrequency catheter.
8. The method of claim 7 , wherein the target comprises a metal device and wherein the step of confirming access involves using a metal contact error produced by a radiofrequency generator as feedback of confirmation.
9. The method of claim 1 , further comprising a step of advancing a guidewire, through the lumen of the flexible radiofrequency catheter, into the second vessel.
10. The method of claim 1 , wherein imaging comprises:
performing CO2 angiography at a hepatic vein to visualize a portal vein under the side view or the top view; and
rotating to the gun-barrel view;
wherein a reference image of the portal vein is provided under the two views using CO2 digital subtraction angiography to provide 3D information of anatomy of the portal vein.
11. The method of claim 1 , wherein the guiding sheath directs the flexible radiofrequency catheter to a select location on the second vessel.
12. The method of claim 1 , further comprising a step of advancing the flexible radiofrequency catheter into the second vessel.
13. The method of claim 12 , further comprising a step of advancing a guidewire through the lumen of the flexible radiofrequency catheter into the second vessel.
14. The method of claim 12 , wherein the step of advancing the flexible radiofrequency catheter into the second vessel involves using at least one depth marker positioned on a proximal portion of the flexible radiofrequency catheter.
15. The method of claim 1 , further comprising a step of placing a stent within the tract formed by the flexible radiofrequency catheter.
16. The method of claim 1 , wherein the first vessel is a hepatic vein and the second vessel is a portal vein.
17. The method of claim 1 , further comprising a step of straightening the radiofrequency catheter with an advancement member while forming the tract.
18. The method of claim 1 , wherein the radiofrequency catheter includes at least one side port.
19. The method of claim 1 , wherein the radiofrequency catheter includes a distal hypotube having an outer diameter configured to fit within an inner diameter of a proximal hypotube.
20. The method of claim 19 , wherein the distal hypotube includes a dome forming an electrode.
