Benefits of technology
The patent describes a system for performing a transjugular intrahepatic portosystemic shunt procedure, which involves inserting a rail and / or anchor line into a patient. The anchor line can be a balloon catheter that is inflated to anchor it to surrounding tissue. The system can also include a stiff sheath or wire to guide the displacement of a needle or outer sheath. The technical effects of this system include improved guidance and stability during the procedure, as well as the ability to measure pressure and perform wedge venography.
Problems solved by technology
The most difficult portion of a TIPS procedure is accessing the portal vein from the hepatic vein.
A significant problem is that the 10 French sheath that is placed in to the hepatic vein often falls out of the hepatic vein and accessing the hepatic vein needs to be repeated.
Also, aiming at the portal vein is usually performed blindly and aiming at and entering the portal vein can be difficult.

A rail and / or anchor system and method for transjugular intrahepatic portosystemic shunt procedures. The system includes a rail and / or anchor line anchorable to surrounding tissue or used as a rail, and configured to guide the displacement of at least one of a needle and an outer sheath. The rail and / or anchor line may include a balloon catheter, and a balloon of the balloon catheter may be configured to selectively anchor the anchor line to surrounding tissue by the balloon being inflated, and unanchor the anchor line to surrounding tissue by the balloon being deflated. The balloon catheter can be stiff so that it can be used as a rail even when not anchored. The balloon catheter may be configured for executing wedge venography, and for measuring pressure at a tip of the balloon catheter while a balloon of the balloon catheter is inflated. The anchor line may include one or more hooks for anchoring the anchor line to surrounding tissue. The one or more hooks may be selectively advanceable and retractable.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of co-pending U.S. Provisional Patent Application Ser. No. 62 / 610,852 filed Dec. 27, 2017, which is incorporated herein in its entirety.FIELD OF THE INVENTION[0002]The present disclosure is generally directed to medical procedures, and more importantly to an improved Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure and system.BACKGROUND OF THE INVENTION[0003]A Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure includes connecting the portal vein (PV) to the hepatic vein (HV) in the liver. The purpose of the procedure is to divert blood from entering the liver, and may be executed on patients with cirrhosis and internal bleeding and / or ascites.[0004]The most difficult portion of a TIPS procedure is accessing the portal vein from the hepatic vein. The device that is currently available requires significant expertise, and typically requires a 10 French sheath to be placed into the ...
