Abstract
A biopsy device comprises a probe assembly and an obturator. The probe assembly comprises a cannula having a closed distal end configured to penetrate tissue, an open proximal end, a first lumen in fluid communication with the open proximal end, and a side aperture located proximal to the closed distal end. The side aperture is in fluid communication with the first lumen. The obturator is removably insertable in the first lumen through the open proximal end. The obturator is configured to substantially block the side aperture when the obturator is inserted in the first lumen. The probe assembly may be inserted in a patient's tissue (e.g., breast) with the obturator disposed in the cannula to block the side aperture. The obturator may then be removed, and a cutter may be advanced through the cannula to sever tissue protruding through the side aperture.
