Abstract
A biopsy probe mechanism and method includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. The elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis. A first echogenic feature and a third echogenic feature are established on the elongate sample receiving member and a second echogenic feature and a fourth echogenic feature are established on the cutting cannula. The elongate sample receiving member and the cutting cannula have a first position in which the first echogenic feature is in longitudinal alignment with the second echogenic feature, and in which the third echogenic feature is in longitudinal alignment with the fourth echogenic feature.
