1-31. (canceled)
An obstruction removing device, comprising:
- an obstruction removing element which is movable from a collapsed position to an expanded position, the obstruction removing element having a wire which has a distal end coupled to an insertion element, the wire also having a proximal end which is slidable on the insertion element.
A method of removing an obstruction from a blood vessel, comprising the steps of:
- providing an obstruction removing element which is movable from a collapsed position to an expanded position;
- positioning the obstruction removing element in a catheter with the obstruction removing element in the collapsed position;
- advancing the catheter through the obstruction;
- moving a distal end of the obstruction engaging element out of the catheter after the advancing step so that the obstruction removing element expands distal to the obstruction, wherein at least part of the obstruction engaging element proximal to the distal end expands within the obstruction;
- and
- removing the obstruction by moving the obstruction engaging element after the advancing step.
