ABSTRACT:
An embodiment of the invention includes a device for collecting body tissue. The device includes an inner end effector comprising a hollow portion, a distal edge that defines an opening of the hollow portion at least a portion of which is sufficiently sharpened to cut body tissue, and a proximal end configured to receive an inner tubular member. The device also includes an outer end effector comprising a flexible extension on a distal end with an edge at least a portion of which is sufficiently sharpened to cut body tissue and biased inwardly toward the hollow portion of the inner end effector to cover the opening, and a proximal end configured to receive an outer tubular member. The inner end effector is slidably disposed within the outer end effector.
