Abstract: A temporary vascular filter system comprising a catheter and an elongate filter slideably carried near the distal end of said catheter. The vascular filter system can be inserted into a vessel percutaneously with the filter in a narrow-diameter “closed position” and expanded into a large diameter “open position” at the desired intravascular site. After deployment, the proximal portion of the catheter can be secured to the patient at the insertion site. While deployed, the filter component is capable of sliding along a portion of the catheter throughout a range of motion. The filter may have two filter meshes, which may have different degrees of porosity. The temporary vascular filter system can be left in the patient for hours or days and then collapsed into a withdrawal tube for removal from the patient.
