Claim:
1. A method of implanting a vessel filter by a femoral approach comprising the steps of: providing a sheath with a substantially straight distal tip; providing a curved pusher with a wire fixedly attached therein, a distal portion of the wire extending distally beyond a distal portion of the curved pusher; inserting the curved pusher and attached wire together into the sheath, the step of inserting both moving the sheath to a curved position from a more straightened position and contacting and advancing the vessel filter in the sheath, the pusher having a distal portion extendable distal of the sheath; rotating about a longitudinal axis of the sheath, the sheath and curved pusher to move a distal opening of the sheath to a more centered position within the vessel; and exposing a filter contained within the sheath by advancing the curved pusher and attached wire together within the sheath, by retracting the sheath from the curved pusher and attached wire, or by relative movement between the sheath and the curved pusher and attached wire.
