1. A biopsy device, comprising:
a vacuum source; an elongate member having a proximal end, a distal end, a lumen in fluid communication with the vacuum source, a longitudinal axis extending between the proximal end and the distal end, and a sample receiving notch, the sample receiving notch having a proximal hole, a distal end wall, and a floor, the distal end wall being located between the distal end and the proximal hole, the proximal hole being separated from the distal end wall along the longitudinal axis, the proximal hole being in fluid communication with the lumen; and a tissue anchor having a cantilever portion with a free end, the cantilever portion configured to extend in a direction from the distal end wall toward the proximal hole, the free end having a tip portion configured to extend toward the floor of the sample receiving notch, the tissue anchor and the proximal hole collectively configured to place tissue received in the sample receiving notch in a state of tension between the tip portion and the proximal hole when a vacuum is applied by the vacuum source to the proximal hole via the lumen. |
