Apparatuses for removing obstructive material from body lumens

An apparatus, the apparatus comprising:

• an elongated shaft having a proximal end portion, a distal end portion, and a lumen extending therebetween, wherein the distal end portion of the elongated shaft is configured to expand from a collapsed delivery state to a funnel-shaped expanded state for engaging and capturing an obstructive material, and wherein, at least in the expanded state, an average cross-sectional dimension of the distal end portion of the shaft is greater than the average cross-sectional dimension of the rest of the shaft,
• wherein the distal end portion is configured to be steered by bending at distal portion proximal to the distal end portion;
• and
• a disrupter configured to extend through the elongate shaft so that a distal end of the disrupter is positioned and rotatable off-axis within the expanded funnel-shaped distal end portion of the elongate shaft, wherein the distal end of the disrupter comprises an elongate longitudinal member having a bend or hook that is configured to be prevented from extending distally beyond the distal end portion of the shaft wherein the disrupter comprises a strut comprising the bend or hook at the distal end configured to strip lodged clot off of an inner diameter of the apparatus.
