Abstract:
An intravascular filter assembly has an expanded state for capturing thrombi in a patient's blood vessel, a first a collapsed state for removal from the patient's blood vessel in a first direction and a second collapsed state for removal from the patient's blood vessel in a second direction. A plurality of first struts extends from a first axial side of a fixed hub, and a plurality of second struts extends from the opposite axial side of the fixed hub. An axially movable hub has a first position radially surrounding the tubular body, a second position axially spaced apart from the fixed hub along the first struts, and a third position axially spaced apart from the fixed hub along the second struts. The first struts are collapsed when the movable hub is in the second position, and the second struts are collapsed when the movable hub is in the third position.
