    摘要： A filter device positionable within a blood vessel for trapping emboli in the vessel, the filter device having a head and a plurality of divergent legs each secured at a first end to the head; each leg having one or more hooks at a second end. The hooks can include an expandable and contractible sleeve or hook that provides securing means for the legs and which also allows for easy removal of the filter device.

    摘要： Retrievable intravascular filters for insertion within a blood vessel are disclosed. A retrievable intravascular filter in accordance with an illustrative embodiment of the present invention includes an apical head operatively coupled to a number of elongated filter legs that can be used to collect blood clots contained within a blood vessel. A bendable anchoring member coupled to or formed integrally with one or more of the elongated filter legs can be used to temporarily or permanently secure the intravascular filter to the wall of the blood vessel.

    摘要： Blood clot filters having self-centering capabilities when placed in a blood vessel are disclosed. A blood clot device in accordance with an exemplary embodiment of the present invention may include a number filter legs formed at least in part of a shape-memory material configured to transform from a centering configuration to a filtering when deployed in the body. An attachment section on the distal section of each filter leg is configured to pierce and secure the filter to the vessel wall at a first location. A bend region may be heat set into the shape-memory material to provide a second contact location along the vessel wall to aid in centering the filter within the vessel. The bend region can be formed by heating the shape-memory material above its final austenite temperature (Af), and then shaping the filter leg to form a pad that abuts the vessel wall during deployment.
