    摘要: A removable filter (10) having a collapsed state and an expanded state for capturing thrombi in a blood vessel is disclosed. The filter comprises a plurality of primary struts (12) and a plurality of secondary struts. Each primary strut in the expanded state extends from a primary strut first end to an anchoring hook (26). Each primary strut extends arcuately along a longitudinal axis and linearly radially. The plurality of primary strut first ends are attached together along the longitudinal axis (x). Each secondary strut in the expanded state extends from a secondary strut first end to a free end. Each secondary strut extends arcuately along the longitudinal axis and linearly radially. The plurality of secondary struts are attached together along the longitudinal axis. The plurality of secondary struts centralize the filter in the expanded state in the blood vessel.

    摘要: An apparatus (10) for filtering blood in a blood vessel of a patient comprises a catheter (30) which is introduced into the blood vessel and advanced to a desired location within the blood vessel, a positioning means (12) having a filter (13) distally attached thereto to be guided through the catheter. In use, the filter is positioned at a location beyond the distal end of the catheter within the blood vessel with the positioning means. The positioning means is then locked to the catheter. The catheter is then anchored to an object located outside of the blood vessel. Thereafter, an amount of blood is filtered within the blood vessel with the filter. The filter can be readily repositioned by unlocking the positioning means from the catheter, repositioning the filter within the blood vessel with the positioning means and then relocking the positioning means to the cather.
