Embodiment Construction

[0043] First refer to figure 1 , describing a multi-needle TIPS device and a method of using the multi-needle TIPS device according to the present invention. The devices and methods described herein are ideal for quickly locating the correct portal vein to establish a shunt 103 connecting the right hepatic portal vein 101 to the right portal vein 102 through the human liver 100 .

[0044] now refer to figure 2 , 3, 4, 5, 6 and 7, the device 200 and its basic components are described separately and in contracted and extended states. figure 2 Device 200 is shown in a retracted state, which is the default state of disengagement. The outer sheath 201 is the basic external component of the device 200 . The outer sheath together with the inner dilator allows a guidewire to be passed into the right hepatic portal vein. The outer sheath 201 is a ten (10) French (for reference, 1 French = 3mm) sheath made of a semi-rigid material. exist Figure 4 In, an outer sheath 201 has a s...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of co-pending U.S. Patent Application Ser. is a continuation-in-part of U.S. Patent No. 8,287,481) which claims priority to expired U.S. Provisional Patent Application No. 61 / 140,693, filed December 24, 2008. technical field [0003] The present application relates to a device and method for rapidly locating the hepatic portal vein to establish a shunt through the human liver between the portal vein and the hepatic portal vein, and in particular to a transjugular intrahepatic portosystemic shunt ("TIPS") device and Methods for establishing TIPS using this device. Background technique [0004] The human liver performs a variety of functions essential to life, including breaking down fat, metabolizing / storing glucose, producing urea, synthesizing amino acids, filtering toxins, storing vitamins and minerals, and metabolizing cholesterol. Typically, a healthy liver receives appr...
