摘要：
A method of implanting a vessel filter by a femoral approach comprising the steps of providing a sheath with a pusher and the vessel filter positioned therein and providing a sheath centering structure movable within the sheath. The centering structure has a distal portion expandable from a collapsed position within the sheath to an expanded position outside the sheath. The steps further include inserting the sheath into the vessel, moving the centering structure with respect to the sheath to enable the centering structure to move from the collapsed position to the expanded position to move a distal tip of the sheath away from a vessel wall and to a more centered position, and subsequently exposing the vessel filter from the sheath to enable the filter to move from a collapsed position to an expanded position. An implantation system is also provided.
