Abstract

A method of removing an implanted vessel filter by a femoral approach comprising the steps of providing a catheter with a curved tip, inserting a straightening device into the catheter to move the catheter tip from a curved position to a more straightened position, advancing the catheter tip through the femoral vein and past a cranial end of the filter, withdrawing the straightening device to enable the catheter tip to return to the curved condition, and inserting a filter grasping device though the catheter and a curved catheter tip to exit a distal portion to grasp the filter.
