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.
