Abstract: The present invention includes an embolic protection device comprising a catheter having a self-expanding embolic filter that is disposed around the catheter proximal to a distal portion, wherein the embolic filter comprises a frame, and the frame defines an opening of the embolic filter that faces the distal end of the catheter; a deployment mechanism that is disposed around at least a portion of the catheter, wherein the deployment mechanism is longitudinally movable with respect to the catheter, the deployment mechanism is configured to contain the embolic filter in a collapsed configuration, and the embolic filter is configured to self-expand upon the longitudinal retraction of the deployment mechanism; and a wire coupled to the frame for expanding the size or diameter of the embolic filter opening.

Abstract: A folding knife is disclosed including a blade, a handle device, and a magnetic piece. The blade may be connected to the handle device so that the blade can pivot with respect to the handle device. The magnetic piece may be fixed to the handle device so that the magnetic piece attracts and pulls the blade into a closed position or into an open position by a magnetic attraction between the blade and the magnetic piece. The magnetic piece may be a post fixed between left and right side plates.
