A filter to be placed in a flow of blood through a vessel. The filter includes a hub disposed along a longitudinal axis and a plurality of anchor members extending from the hub. Each anchor member includes either a cranial extension or a caudal extension at a distal end thereof. At least one anchor member distal end is spaced from the hub at each of a first, second, and third distance along the longitudinal axis. The filter also includes a plurality of locator members extending from the hub, the locator members alternatingly interposed between the anchor members.
