Transjugular Intrahepatic Portosystemic Shunt Pressure Measurement Systems and Methods

A medical device comprising:

• an elongate member comprising an inner wall and an outer wall;
• a first opening defined by the outer wall;
• a second opening defined by the outer wall, spaced apart longitudinally from the first opening;
• a lumen, defined between the inner wall and the outer wall, the lumen extending between the first opening and the second opening;
• and
• a pressure differential mechanism located within the lumen for measuring a pressure differential between a first pressure at the first opening and a second pressure at the second opening.

A method of measuring pressure during an intrahepatic portosystemic shunt procedure, the method comprising:

• measuring a first pressure at a first location associated with the intrahepatic portosystemic shunt procedure within a patient's body using a first pressure measurement mechanism;
• and
• measuring a second pressure at a second location associated with the intrahepatic portosystemic shunt procedure within the patient's body using a second pressure measurement mechanism;
• wherein the first pressure and the second pressure are measured while substantially maintaining a position of the first pressure measurement mechanism at the first location and maintaining a position of the second pressure measurement mechanism at the second location.
