  • Publication number: 20070016101
    Abstract: A biopsy device used to capture a tissue sample by placing the tissue under tension, thus allowing a greater sized sample with increased quality. The device uses a rotating cannula and stylet with a concave “sample notch.” The rotation of the stylet places the tissue under tension while the rotation of the cannula as it is fired severs the sample.
