Abstract
A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.
