    摘要: The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts and a plurality of secondary struts. The plurality of primary struts has first ends attached together along a longitudinal axis. Each primary strut has an arcuate segment extending from the first end to an anchoring hook. The primary struts are configured to move between an expanded state for engaging the anchoring hooks with the blood vessel and a collapsed state for filter retrieval or delivery. Each primary strut is configured to cross another primary strut along the longitudinal axis in the collapsed state such that each anchoring hook faces the longitudinal axis away from the blood vessel for filter retrieval or delivery. The plurality of secondary struts has connected ends attached together along the longitudinal axis. The secondary struts extend therefrom to free ends to centralize the filter in the expanded in the blood vessel.
