Claim 18:
19. An excisional device, comprising:
an outer sheath defining an inner and outer diameter, a longitudinal axis, a proximal portion and a distal open portion; and
a tubular inner assembly configured to be received within and, during operation of the excisional device, move parallel to the longitudinal axis of the outer sheath, the inner assembly defining a proximal portion, a distal portion and a body portion between the proximal and distal portions, the distal portion being extendable beyond the outer sheath to be positioned adjacent tissue to be sampled, with the distal portion comprising a pair of articulable curved blades whose actuation is independent of longitudinal movement of the inner assembly within the outer sheath, the articulable curved blades being configured to selectively open apart and close together to provide a cored specimen by coring through and cutting parting-off the cored tissue, respectively;
wherein the articulable curved blades, when in the closed position within the outer sheath, are oriented adjacent to and follow the inner diameter of the outer sheath and have a sharp outwardly facing blade edge.
