Patent abstract
A compact retrievable blood clot filter and a method of retrieving the filter. The retrievable filter has a primary hub, a set of filter struts having a conical configuration and extending from the primary hub, and a set of alignment struts connected to the filter struts to provide centering of the filter. A set of control struts connected to the alignment struts has a secondary hub which is axially movable relative to the primary hub. Movement of the secondary hub causes the control struts to pull the alignment struts radially inward into a retractable state for retrieval of the filter.
