Abstract
Medical devices with radiopaque three dimensional filtration matrices provide for improved visualization of the device within a vessel. In some embodiments, the three dimensional filtration matrix comprises fibers, such as surface capillary fibers. Visualization of the three dimensional filtration matrix provides for an evaluation of the proper deployment of the three dimensional filtration matrix. Radiopaque surface capillary fibers can be advantageously incorporated into other medical devices. Radiopaque surface capillary fibers can be formed by extrusion of a radiopaque polymer or polymer composite.
