摘要
A blood filter delivery system for delivering a filter into a vein from either a femoral or jugular access. The preferred system includes an introducer and a push-rod with a spline member disposed along the push-rod and a pusher member disposed on a distal end. The spline member has a main body, first and second boss portions spaced apart along the longitudinal axis to provide a gap for retaining anchor members of the filter during delivery via the introducer. In an alternative embodiment, a preferred filter includes first and second filter structures diverging in opposite directions. A link is connected to portions of each of the first and second filter structures so that each filter structure can be independently collapsed into a generally cylindrical shape.
