More Information
Summary:A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, and a distal end. A tissue penetrating tip includes a proximal base and a sharp distal point. The proximal base is secured to the distal end of the elongated probe. The sharp distal point is distal to the proximal base and is aligned with the central longitudinal axis. The tissue penetrating tip has a plurality of concave surfaces annularly arranged to form at least three adjacent pairs of concave surfaces. Each concave surface of the plurality of concave surfaces extends from the proximal base to the sharp distal point. Each adjacent pair of concave surfaces intersect to form a concave curved cutting edge. Cumulatively, the at least three adjacent pairs of concave surfaces form a plurality of concave curved cutting edges that distally terminate at the sharp distal point.
