1. A method of removing an implanted vessel filter by a femoral approach comprising the steps of:
- providing a catheter with a tip;
inserting a curved device into the catheter to a position proximal of the tip;
advancing the catheter tip through the femoral vein and past a cranial end of the implanted filter;
inserting the curved device into the catheter tip to move the catheter tip from a first more straightened position to a second more curved position; and
inserting a filter grasping device through the curved device, catheter and curved catheter tip to exit a distal portion of the catheter to grasp the filter, wherein the tip of the catheter terminates in an opening and the step of inserting the curved device moves the opening to face a proximal portion of the catheter and the cranial end of the filter.
