Abstract

An implantable lumen filter (200) is described. The implantable lumen filter includes a body (202) having a proximal end (202a), a distal end (202b), and a generally tapered outer surface (204). The outer surface is formed by a plurality of struts (206a, 206b). The plurality of struts forms a plurality of apertures (210). The apertures are dimensioned to inhibit and/or to lyse particulates of a selected size from passing through the apertures. The body (202) is transitionable from a collapsed state toward a deployed state. The implantable lumen filter includes an engaging portion (220) having a proximal end (220a) and a distal end (220b). The proximal end of the engaging portion is connected to a distal end of the body. The engaging portion has a generally annular shape and is configured to engage an inner surface of a body lumen.
