Abstract

A blood clot filter which is collapsible toward a central longitudinal axis into a collapsed configuration for insertion into a blood vessel and which is radially expandable outwardly from the longitudinal axis to an expanded configuration for contact with the inner wall of the blood vessel at two longitudinally spaced locations. A first plurality of spaced, elongate arms, in the expanded configuration of the filter, curve outwardly away from the longitudinal axis toward the trailing end of the filter to form a first filter basket. These arms prevent movement of the filter in a first longitudinal direction. A second plurality of spaced elongate legs angle outwardly away from the longitudinal axis toward the leading edge of the filter in the expanded configuration thereof. These second legs form a second filter basket opening toward the leading end and prevent longitudinal movement of the filter in a second direction opposite to the first direction.
