    Abstract: A device for collecting a tissue sample includes an outer sheath extending from a proximal end to a distal end and including a lumen extending therethrough. The device also includes a needle movably housed within the outer sheath. The needle extends from a proximal end to a serrated distal end and including a channel extending therethrough. The needle is longitudinally movable relative to the outer sheath between an insertion configuration, in which the distal end of the needle is proximal of the distal end of the outer sheath, and a tissue collecting configuration, in which the distal end of the needle extends distally past the distal end of the outer sheath to penetrate tissue and collect a tissue sample in the channel. In addition, the device includes a drive mechanism rotating a distal portion of the needle about a longitudinal axis thereof as the needle is moved between the insertion and tissue collecting configurations.
