摘要： Tissue markers, systems for marking tissue, and methods of using tissue markers. A tissue marker may have a body with a first surface and a second surface, a plurality of coupling sites, and a plurality of elongate members. The tissue marker may include a remotely visible material. The tissue marker may have a delivery configuration that is different from a deployed configuration.

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.
