Abstract
A retrieval device for collecting a specimen 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 device also includes first and second snarecoil elements that are formed as part of the inner member. Each snarecoil element has an arcuate shape and is attached to an inner surface of the outer cannula. The snarecoil elements being deformable such that rotation of the inner member relative to the outer catheter results in the snarecoil elements collapsing toward a center of the outer cannula member resulting in either the tissue specimen being captured between the two snarecoil elements in one embodiment or being sheared by the two snarecoil elements in another embodiment.
