Abstract
An implantable medical device such as a filter has a generally conical shape formed by a set of filter legs extending from a free distal end to an apex of the assembly and specifically to a coupling device. A retrieval element such as a hook extends from the hub of. A spacer member is disposed at the hub and is formed of a plurality of curved wire elements. The spacer member has a radius or width smaller than the greatest radius of the filter device, defined by the free ends of the filter legs. The spacer member allows the filter assembly to tilt within a vessel but limits the tilt to a maximum desired or permitted tilt, ensuring that the retrieval device remains spaced from the vessel wall and therefore not subject to tissue ingrowth.
