    摘要： A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.

    摘要： A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted and to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

    摘要： Some embodiments include methods in which spaced-apart first features are formed from a first material having a reflow temperature. Second material is formed along sidewalls of the first features, and third material is formed over the second material and the first features. The third material may be formed at a temperature above the reflow temperature of the first material, and the second material may support the first features so that the first features do not collapse even though they are exposed to such temperature. In some embodiments the third material has an undulating topography. Fourth material may be formed within the valleys of the undulating topography, and subsequently the first features may be removed together with at least some of the third material to leave a pattern comprising second features formed from the second material and pedestals formed from the fourth material.
