Abstract
A biopsy device includes a vacuum source, and an elongate member having a lumen and a sample receiving notch. The sample receiving notch has a proximal hole, a distal end wall, and a floor. The proximal hole is separated from the distal end wall along the longitudinal axis. The proximal hole is in fluid communication with the lumen. A tissue anchor has a cantilever portion with a free end. The cantilever portion is configured to extend in a direction from the distal end wall toward the proximal hole. The free end has a tip portion configured to extend toward the floor. The tissue anchor and the proximal hole are 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.
