Abstract:
1. A filtering device for use in a blood vessel, comprising: a body member; a plurality of struts including a proximal end region, a distal end region, and a distal tip, the plurality of struts fixedly attached to the body member and extending therefrom; at least some distal tips of the plurality of struts being configured as an anchoring member directly coupled to the distal end region of that strut of which it is a distal tip by a weakened region, the anchoring member configured to securely attach to a wall of the blood vessel; and wherein the weakened region is configured to fail upon application of a force thereto, releasing the anchoring member from the distal end region of that strut of which it is a distal tip thereby separating the distal tip of the strut from the filtering device; wherein the force is lower than that required to detach the anchoring member from the wall of the blood vessel, such that after the weakened region fails, the anchoring member remains attached to the wall of the blood vessel.
