摘要
The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of struts having first ends attached together along a longitudinal axis of the filter. Each strut has a body member extending from the first end along the longitudinal axis to an anchoring hook defining a strut axis. Each strut is configured to move along a strut path relative to the longitudinal axis between an expanded state for engaging with the blood vessel and a collapsed state for filter delivery or retrieval. Each anchoring hook has an angle of up to about 90 degrees relative to the strut axis.
