ABSTRACT:
A biopsy instrument is provided which has a retractable cutting wire or filament looped external to the innermost surface of the distal end of the tissue cutting cylinder. Forceful retraction of the cutting wire will cause displacement and closure of a loop of wire over the distal margin of the cored tissue biopsy, thus freeing the biopsy specimen in its entirety from its original locus and allowing removal of the entire cored biopsy from the body substantially without stretching the specimen along its length.
