摘要：
An intravascular filter configured for upstream or downstream retrieval and a method for retrieving an intravascular filter from a patient's vena cava through the patient's femoral vein. The filter includes a downstream hub, an upstream hub, a plurality of primary struts extending from the downstream hub to the upstream hub, a plurality of secondary struts extending upstream from fixed ends housed in the downstream hub to free ends, secondary strut eyelets disposed at the free ends of the secondary struts, a loop member disposed through the secondary strut eyelets, an upstream coupling element disposed with the upstream hub, and a tether extending from the loop member to the upstream coupling element.
