摘要:
A removable filter 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 and a plurality of secondary struts. Each primary strut in the expanded state extends from a primary strut first end to an anchoring hook. 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. 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.
