Claim 14:
15. An obstruction removal device comprising:
a pusher having a pusher lumen extending between a distal end of the pusher and a proximal end of the pusher;
a plurality of engaging members connected at the distal end of the pusher;
an elongated element positioned in the pusher lumen and extending from the distal end of the pusher, wherein the elongated element is connected the plurality of engaging members, wherein the elongated element extends beyond the proximal end of the pusher, and wherein the elongated element is longitudinally moveable relative to the pusher so as to cause the plurality of engaging members to adopt an expanded shape or a collapsed shape;
a locking mechanism selectively preventing the elongated element from moving relative to the pusher and thereby locking the plurality of engaging members in at least one of the expanded shape or the collapsed shape; and
a plurality of structures mounted over the elongated element and configured to contact at least one of the plurality of engaging members, wherein each of the plurality of engaging members has its own dedicated structure of the plurality of structures, and wherein each of the plurality of structures are located within each of the plurality of engaging members; and,
wherein longitudinal movement of the elongated element adjusts all of the plurality of engaging members between the expanded shape or the collapsed shape.
