Abstract
An apparatus method for establishing a Transjugular Intrahepatic Portosystemic Shunt (“TIPS”) between the portal vein from a hepatic vein. The apparatus comprises a multi-needle TIPS device designed to facilitate safer and more rapid catheterization of the portal vein. The method utilizes the multi-needle TIPS device to access the portal vein from the hepatic vein approach. The multi-needle TIPS device and method provides numerous benefits over previous TIPS devices and procedures and results in shorter and safer procedures. Use of multiple needles increases the probability of finding the portal vein more quickly.
