1. An extraction device, comprising:
a delivery shaft having a lumen and a distal end;
a first wire forming a first arc and being positionable distal to the distal end of the delivery shaft while ends of the first arc are at a distalmost end of the delivery shaft;
a second wire forming a second arc and being positionable distal to the distal end of the delivery shaft while ends of the second arc are at the distalmost end of the delivery shaft, wherein a distalmost extent of the first wire is distal to a distalmost extent of the second wire, wherein the first wire and the second wire are separately retractable relative to the delivery shaft;
a first guide and a second guide each moveable along the first wire toward the distalmost extent of the first wire from a first position to a second position more distal than the first position; and
a cover attached to the first guide and the second guide,
wherein, while in the second position, the first wire resides within a first plane and the second wire resides within a second plane that is perpendicular to the first plane, and wherein the cover encompasses an outer cross-sectional dimension of a capture region defined by each of the first wire and the second wire.
