The needle comprises a first lumen configured to receive the cutter, a transverse tissue receiving aperture in fluid communication with the first lumen, and a second lumen, wherein the second lumen is in fluid communication with the first lumen. The needle extends from the body, and the cutter is rotatable and translatable within the first lumen of the needle, wherein the cutter has a length. The valving mechanism is configured to selectively change a state of fluid communication to the second lumen, wherein the valving mechanism is located within the body. The valving mechanism comprises a manifold and a valving member within the manifold, wherein the manifold defines a hollow interior and comprises at least one port extending from the hollow interior of the manifold and in fluid communication with the hollow interior. The valving member is disposed about the cutter and is operable to translate within the hollow interior of the manifold along a portion of the length of the cutter. The valving member is configured to selectively seal or couple a first port of the at least one port relative to the second lumen of the needle based on the longitudinal position of the valving member within the hollow interior of the manifold.
