Abstract:
1. A filter comprising, a proximal end member comprising a first cylindrical portion; a first notch extending inwardly from a wall of the first cylindrical portion; a distal end member comprising a second cylindrical portion; a second notch extending inwardly from a wall of the second cylindrical portion; a first plurality of expandable legs, wherein each leg of the first plurality of expandable legs extends from a proximal end coupled to the proximal end member to an apex of a first plurality of apices such that the first plurality of legs forms a first generally conical shape between the proximal end member and the first plurality of apices; a second plurality of expandable legs, wherein each leg of the second plurality of expandable legs extends from a distal end coupled to the distal end member to an apex of a second plurality of apices such that the second plurality of legs forms a second generally conical shape between the distal end and the second plurality of apices; a plurality of connectors, each connector coupled to, and extending between, an apex of the first plurality of apices and an apex of the second plurality of apices, wherein the apices of the first plurality of apices and the apices of the second plurality of apices all have substantially the same radial displacement from a longitudinal axis of the filter; a first barb extending from a first leg of the first plurality of legs from a position proximal to a first apex of the first plurality of apices; and a second barb extending from a second leg of the second plurality of legs from a position distal to a second apex of the second plurality of apices; wherein a connector of the plurality of connectors is coupled to the first leg and the second leg and wherein the first barb is disposed on an opposite lateral side of the connector from the second barb.
