Abstract
Shaped liver biopsy sheaths and methods for transfemoral transcaval liver access are disclosed. The present invention provides methods of obtaining a tissue sample from the liver of a patient, the methods comprising inserting a hollow sheath, such as a stiffened sheath with an angled tip, through a femoral vein into a portion of the inferior vena cava (IVC) adjacent to the liver, wherein the sheath's tip is in the intrahepatic IVC and wherein the sheath has a shape that brings the tip of the sheath adjacent to the wall of the IVC at an angle that is optimal to allow penetration of the wall of the IVC by a biopsy needle, and inserting a biopsy needle through the sheath and through the wall of the NC into the liver to obtain a tissue sample from the liver.
