Abstract
An extraction device can include 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, and 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. A distalmost extent of the first wire is distal to a distalmost extent of the second wire. The first wire and the second wire are separately retractable relative to the delivery shaft.
