Abstract: In embodiments of an obstruction removal device, system, and/or method, a removal tool is disposed at a distal end of a delivery tool and configured to at least partially separate an obstruction from an inner surface of a vasculature. An expandable member is also coupled to the delivery tool. The expandable member includes a proximal end that is free or slidably coupled to the delivery tool. The proximal end of the expandable member is configured to invert or slide toward a distal end of the expandable member, thereby causing the expandable member to surround at least a portion of the obstruction and the removal tool so that the obstruction is captured between the expandable member and the removal tool, when the delivery tool is withdrawn from the vasculature to remove the removal tool and the obstruction from the vasculature.

Abstract: An obstruction removal device is configured to be inserted through a catheter and at least partially extended into a vasculature from a distal end of the catheter. The obstruction removal device includes: a base member configured to engage one or more guide stops at the distal end of the catheter; a tubular member coupled to the base member and configured to apply a suction force from the catheter to an obstruction to remove the obstruction from the vasculature; and an expandable member surrounding the tubular member. The expandable member is configured to transition from a contracted state to an expanded state after the expandable member is at least partially extended into the vasculature from the distal end of the catheter. The expandable member is further configured to at least partially surround the obstruction as the obstruction is being removed from the vasculature.
