Abstract
A retrieval device for retrieving and capturing a foreign body specimen, such as a tissue specimen or a foreign material specimen, according to one exemplary embodiment includes an outer cannula member having an inner lumen and an inner member received within the inner lumen such that the inner member can rotate relative to the outer cannula. The inner member has a distal end that extends beyond a distal end of the outer cannula. The device also includes a first snare coil having a first end and an opposing second end. The first end of the snare coil is attached to an outer surface of the outer cannula and the second end of the snare coil is attached to the inner member to allow the snare coil to be actuated by rotating the inner member relative to the outer cannula so as to either open or close the snare coil for collecting the specimen.
