Abstract
The present invention is a luminal filter having wall contacts. The filter is formed to include: a plurality of filter elements interconnected so as to form a filter body shaped in a free recovery form and having a plurality of apertures disposed between and defined by the interconnected filter elements. The apertures are dimensioned so as to inhibit a thrombus of a selected size from passing through the apertures and being dimensioned so as to allow blood components smaller than the selected size to pass through the apertures. The polymeric wall contact is coupled to the filter and disposed on an external surface thereof. Optionally, a fastener can be used to secure the wall contact to the filter.
