Embodiment Construction

[0032] The present invention provides a transjugular catheter with intravascular imaging for use in a transjugular intrahepatic portosystemic shunt (TIPS) procedure and a method for performing a TIPS procedure using such a catheter. The methods and devices of the present invention may be used to treat patients with cirrhosis, portal hypertension, bleeding from esophageal varices, and other related conditions. The device of the present invention provides a transcatheter with a wire extension, wherein the wire can be used to pierce out of a first blood vessel and into a second blood vessel to create a new connection between the two blood vessels in the liver. Figure 1-3 Included to illustrate the general arrangement of the patient's organs and relevant parts of the portal system.

[0033] figure 1 Vital organs of the human body 101 are shown. The patient's trachea 105 extends down to the lungs 109 , above the liver 117 . The heart 113 is between the lungs, while the large inte...

Abstract

The invention provides methods and devices for treating liver cirrhosis or portal hypertension by creating an intrahepatic shunt, or new passage, from a portal vein of a patient to a hepatic vein using a device with intravascular imaging capabilities and pressure sensing capabilities or positioning mechanisms. The integration of intravascular imaging aids in the precise placement of the shunt and pressure measurement may verify successful shunt creation. An apparatus may include a catheter with an extended body for insertion into a hepatic vein of a patient, an intravascular imaging device and a needle exit port on the distal portion of the extended body, and a needle disposed within a lumen in the catheter and configured to be pushed out of the exit port and extend away from a side of the extended body, in which the needle includes a pressure sensor.

Description

technical field [0001] The present invention relates to devices and methods for creating an intrahepatic shunt. Background technique [0002] People with cirrhosis can have bloody vomit or stool. Left untreated, cirrhosis can cause shock and death. Cirrhosis, which can result from alcohol abuse, hepatitis, disease, or an unknown cause, is characterized by scar tissue and nodules in the liver that lead to loss of liver function. Cirrhosis presents resistance to blood flow through the portal system, causing inappropriate pressure or portal hypertension. The effects of portal hypertension include collateral blood flow that dilates the blood vessels surrounding the esophagus. Swollen blood vessels in the esophagus, or varicose veins, are called burst, causing the varicose veins to bleed. After an esophageal varice has already bled once, there is a high risk of rebleeding. Bleeding varices can manifest as bloody stools and vomiting, and bleeding from varices can lead to shoc...
