Blood vessel occlusion auger

Abstract

Abstract An occlusion auger (1000) including a core wire (20) configured for asymmetric deflection when operated to deflect into a deflection state. The deflected core wire has an extrados (34), a tool nose (27), and an intrados (35). When disposed adjacent an occlusion (320) in a vessel (300), 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 (340) 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.
