Abstract

An apparatus for use with a minimally invasive medical procedure into human breast tissue includes a cannula and an obturator. The cannula includes an open distal end, a lateral opening proximate to the open distal end, and a longitudinal lumen communicating with the lateral opening and the open distal end. The lumen has a non-circular cross-section. The obturator is sized for insertion into the cannula. The obturator has a distal end extending from the open distal end of the cannula when the obturator is inserted fully into the cannula. The obturator has a recess proximate of the distal end of the obturator. The recess is positioned along a portion of the length of the obturator to align with the lateral opening of the cannula when the obturator is inserted fully into the cannula.
