1. A medical device for removing an obstruction from a blood vessel, the medical device comprising:
a first capturing portion having a first distal end, a first proximal end, and a first capturing surface extending between the first distal end and the first proximal end, wherein the first distal end defines a first opening, and wherein the first distal end includes a plurality of first flanges spaced around the first opening, each first flange including one or more wires extending continuously along a peripheral edge of the respective first flange;
a second capturing portion having a second distal end, a second proximal end, and a second capturing surface extending between the second distal end and the second proximal end, wherein the second proximal end defines a second opening, and wherein the second proximal end includes a plurality of second flanges, each second flange including one or more wires extending continuously along a peripheral edge of the respective second flange; and
a connecting portion formed from a plurality of wires that extend at least partially through the first and second capturing portions, wherein at least some of the plurality of wires of the connecting portion diverge from each other within the second capturing portion and return to converge together with the connecting portion, wherein the connecting portion is configured to be coupled to an elongate delivery member.
