Abstract

The device comprises a plurality of elongated filamentary loops extending outwardly from a central column in one or more tiers, the filaments having hooks backed by offset barriers at their free ends. The column is preferably hollow. The device is inserted into a passageway such as a vein with the loops held back toward the column and biased to open when released, and hook into the vein wall to form a network or web to engage and hold blood clots in the vein. The device anchors itself in place without injury to the wall of the passageway. It is self-centering and self-cleaning. Preferably the device is inserted over a wire guide threaded through the column and introduced into the vein through a hollow needle puncture.
