Abstract: A method and a system using a helicoidal structure wound out of a plurality of metallic wires into a universal connector for reversibly coupling a distal end portion of an extension wire to a proximal end portion of a guide wire. The universal connector is configured for receiving the proximal end portion of the guide wire into the connector lumen and is made as a single-piece unit built to sustain increased separation forces tending to disconnect the extension wire from the guide wire. The universal connector accommodates coupling to different configurations of commercially available guide wire proximal terminations.

Abstract: A blood occlusion auger having an in vivo distal auger tool coupled in operative association with an ex vivo auger control for opening and traversing occlusions in a blood vessel The auger control allows the selection of predetermined threshold forces and step-lengths values and operates in successive repetition of identical sequential stages, to traverse occlusions. Once disposed adjacent an occlusion, the auger tool, commanded by the auger control, operates in two states, first to radially dilate the vessel and second to penetrate distally into a furrow.

Abstract: An occlusion auger including a core wire configured for asymmetric deflection when operated to deflect into a deflection state. The deflected core wire has an extrados, a tool nose, and an intrados. When disposed adjacent an occlusion in a vessel, the tool nose and the extrados embed into a respectively, nose depression (ND) and extrados depression (ED) opposite to each other, whereby the vessel is dilated asymmetrically and radially outward for opening a furrow in the occlusion. When released from the deflection state to a released state, the tool nose exits the nose depression and translates distally into the furrow before release of the extrados out of the extrados depression, whereby the tool nose translates distally away from the extrados depression, by one distally step length for each sequence of operation from the deflected state to the released state.
