Abstract
A filter may have an apical hub and a plurality of divergent legs. A first attachment member may be separate from, but attached to the second end of at least one of the plurality of divergent legs. A second attachment member may be separate from, but attached to a stent. The first and second attachment members may be separate from, but attachable to one another to releasably attach the filter to the stent. One of the first attachment member and the second attachment member may include an attachment wire that is positioned in a lumen of a tubular member or one of the first attachment member and the second attachment member may comprise a cannula. In some implementations, an upward motion applied to the retrieval connection member may disengage at least one attachment wire of the first attachment member from the second attachment member.
