1. A method of removing an obstruction from a blood vessel, comprising the steps of:

  • providing an obstruction removing element having an expandable portion which is movable from a collapsed position to an expanded position, the obstruction removing element also having a proximal portion and means for stopping distal advancement of the proximal portion of the element to prevent expansion of the obstruction engaging element beyond the expanded position, the preventing means being coupled to the proximal portion of the element;

    advancing the obstruction removing element into the obstruction with the obstruction removing element in the collapsed position;

    permitting the obstruction removing element to move toward the expanded shape after the advancing step; and

    moving the obstruction removing element proximally to engage the obstruction, the preventing means preventing distal displacement of the proximal portion of the element relative to the insertion element when the obstruction removing element is moved proximally.
