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.

A method of retrieving a retrievable blood clot filter having an axis, a primary hub, a set of filter struts, and a set of alignment struts having first and second ends and being connected to the filter struts, a secondary hub, and a plurality of connector elements, each of said connector elements extending from said secondary hub to form a juncture with one of said alignment struts, the method comprising:
- capturing the secondary hub of the filter in a deployed state;
- axially moving the captured secondary hub relative to the primary hub to move said alignment struts radially inward;
- and
- moving a sheath over the filter struts to enclose the plurality of filter struts.
