A biopsy system for harvesting larger volumes of tissue as compared to standard core biopsy needles. The system has a needle with a lumen, an aperture disposed at the distal end of the needle and connected to the lumen, and a cutting mechanism adapted to cut tissue. When the needle is rotated after it is inserted to a target tissue, the cutting mechanism cuts from the tissue and directs the cut tissue into the cavity and lumen. The cut tissue has a generally coiled in shape. The biopsy system can further cauterize the contacting tissue.
