Abstract

In various embodiments, the present specification discloses an aspiration catheter that has a slim profile, can effectively anchor or self-center in a location, within a patient's vessel lumen, to better provide directed suction or vacuum/negative pressure, and/or can effectively funnel or direct suction or vacuum/negative pressure toward an occlusion or obstruction within the patient's vessel lumen.
