Abstract
Exemplary embodiments of an apparatus can be provided for obtaining portions or samples of tissue from a target region of a biological tissue. One or more needles can be provided that have a small internal diameter, e.g., about 1 mm or less, and the needles can be configured to extract the tissue portions when the needles are inserted into and withdrawn from the tissue. Windows and/or markings can be provided on the wall of the needles to facilitate access to the sample. The needles can be provided in an enclosure, and an actuator can be provided to direct the needles into the tissue and/or withdraw them. A plurality of tissue portions having known relative locations in the target region can be obtained, and extraction of the tissue portions can be well-tolerated by the tissue as compared with conventional punch biopsies or the like.
