Transjugular intrahepatic portosystemic shunt device

An apparatus method for establishing a Transjugular Intrahepatic Portosystemic Shunt between the portal vein from a hepatic vein. The apparatus comprises an elongated hollow outer guide; an outer handle having an inner lumen and a first luer lock, the outer handle attached at a proximal end of the outer guide, the outer guide in flow communication with the inner lumen and the first luer lock; an elongated hollow inner needle; and a hub having a second luer lock, the hub attached at a proximal end of the inner needle, the inner needle in flow communication with the second luer lock. The inner needle is slidingly received into the outer guide through the inner lumen. The inner needle rotates within the outer guide by manipulation of the hub; and a distal tip of the inner needle is deployed out of and beyond a distal tip of the outer guide. 种用于在从肝门静脉到门静脉之间建立静脉肝内门体分流的装置方法。所述装置包括，细长的中空外导向件；具有内导管和第鲁尔接头锁的外手柄，所述外手柄附连在外导向件的近端，所述外导向件与内导管和第鲁尔接头锁流体连通；细长的中空内针；以及具有第二鲁尔接头锁的毂套，所述毂套附连在所述内针的近端，所述内针与第二鲁尔接头锁流体连通。所述内针通过导管滑动地接收在外导
