An implantable lumen filter (100) is described. The implantable lumen filter includes a proximal portion (103a) having a generally-tapered outer surface defined by a plurality of outer struts (106). The implantable lumen filter may also include a distal portion (103b) having a generally-tapered outer surface defined by a plurality of outer struts (106b) coupled together at the distal end (102b) of the distal portion. The implantable lumen filter may also include an apex (105) comprising the connection between the proximal and distal portions. The apex may define an outer dimension of the implantable lumen filter. The outer surface of the proximal portion is dimensioned to direct particulates towards the outer dimension.
