Abstract
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.

An implantable lumen filter, comprising:
- a body comprising:
- a proximal portion having a generally-tapered outer surface, the outer surface of the proximal portion being defined by a plurality of elongated outer struts coupled together at a proximal end of the proximal portion and tapering outward towards a distal end of the proximal portion generally in alignment with a longitudinal axis of the body, adjacent outer struts of the proximal portion defining v-shaped apertures in the outer surface of the proximal portion;
- a distal portion having a generally-tapered outer surface, the outer surface of the distal portion being defined by a plurality of elongated outer struts coupled together at a distal end of the distal portion and tapering outward towards a proximal end of the distal portion, the proximal end of the distal portion being coupled to the distal end of the proximal portion;
- and
- an apex extending around the body proximate the distal end of the proximal portion and defining an outer dimension of the body.
