Abstract: A device for percutaneously excising tissue. In an embodiment, the device comprises an elongate body including a first member having a distal cutting end and a second member that slidingly engages the first member. In addition, the second member includes a tissue capture chamber having an opening facing the first member. Further, the first member is moveable relative to the second member between an opened position and a closed position, wherein the first member is disposed across the tissue capture chamber of the second member when the first member is in the closed position.

Abstract: A device for retrieving an excised tissue segment. In an embodiment, the device comprises an elongate body having a central axis and an outer surface. In addition, the device comprises at least two prongs extending from the body in a direction substantially parallel to the central axis. Each prong includes a fixed-end coupled to the body, a free-end distal the body, an inner surface, and an outer surface substantially contiguous with the outer surface of the body. Further, the device comprises a space extending between the inner surfaces of the prongs that accommodates excised tissue.

Abstract: A device for excising tissue. In an embodiment, the device comprises an outer sleeve. In addition, the device comprises an inner tubular member slidingly received within the outer sleeve. Further the device comprises a cutting head connected to a distal end of the inner tubular, wherein the cutting head comprises at least three aims extending axially from the inner tubular. Still further, the device has an open position in which the cutting head extends from the outer sleeve, and a closed position in which the cutting head is at least partially disposed within the sleeve.
