Claim 6:
7. An obstruction removal device, comprising:
a continuous wire mesh structure coupled to a delivery tool, wherein respective portions of the continuous wire mesh structure form:
a removal tool disposed at a distal end of the delivery tool and configured to at least partially separate an obstruction from an inner surface of a vasculature, wherein the removal tool comprises a conical or umbrella-shaped section configured to at least partially surround the obstruction;
an expandable member coupled to the delivery tool, the expandable member including a proximal end that is slidably coupled to the delivery tool, wherein 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tool so that the obstruction is captured between the expandable member and the removal tool when the delivery tool is withdrawn from the vasculature to remove the removal tool and the obstruction from the vasculature; and
an obstruction landing area between the removal tool and the expandable member, wherein the removal tool, the expandable member, and the obstruction landing area are separated by marker bands that are coupled to the delivery tool.
