1. An embolism protection device comprising a. at least about 50 biocompatible surface capillary polymer fibers, b. a wire, c. a hypotube having a distal end and a proximal end, and d. a distal coil, wherein the fibers are distally bound and proximally bound with relative movement of the wire and the hypotube changing the distance between the distally bound end and the proximally bound end of the fibers, wherein the wire extends through a lumen of the hypotube, wherein the distal coil covers the w/e at its distal end, wherein the fibers have a first configuration in which the fibers are confined within a narrow profile configuration and a second configuration in which ends of the fibers are constrained while the remaining portion of the fiber is unconstrained with respect to the narrow profile, wherein the first configuration has substantially aligned fibers and the second configuration has the center of the fibers projecting outward to form a filtration matrix that conforms to a geometry of a surrounding vessel, and wherein relative movement of the wire and the hypotube transitions the fibers from the narrow profile configuration to the second configuration.
