Abstract

A filter device has a single hub and a plurality of filter struts extending in a first longitudinal direction. A plurality of wire loops extend in a second longitudinal direction opposite the filter struts. The filter struts and wire loops each engage the vessel wall of a body lumen when deployed. The wire loops limit the filter device from becoming tilted and embedded in the vessel wall. A retrieval device includes a sheath and a snaring mechanism. The snaring mechanism engages a hook member of the filter and the sheath envelopes the wire loops and filter struts. The sheath will cause the wire loops to bend and fold over the filter struts during retrieval such that the wire loops and filter struts extend in the same longitudinal direction after being enveloped by the sheath.
