Patent ID: 8529465

Claim:
A biopsy system comprising: (a) a biopsy device operable for taking one or more biopsy samples from a patient, the biopsy device comprising: (i) a body portion having an alignment chamber disposed at a proximal end of the body portion, wherein the alignment chamber is defined by an outer perimeter having a non-circular cross-section, (ii) a tissue sample holder comprising at least a part configured to selectively cover and uncover the alignment chamber, and (iii) a hollow biopsy needle extending distally from the body portion, the biopsy needle having a proximal end, a closed distal end, an interior lumen, and a lateral aperture configured to receive tissue; and (b) a marker delivery device comprising: (i) a marker deployer tube having a proximal end, a distal end, and a side opening formed in a sidewall of the marker deployer tube, and (ii) an alignment member associated with the marker deployer tube and configured to matingly engage with and be received by the alignment chamber on the biopsy device when the at least a part of the tissue sample holder uncovers the alignment chamber, wherein upon and during said receipt, the alignment member is non-rotatable with respect to the alignment chamber, wherein the alignment member has a non-circular cross-section that is complementary to the non-circular cross-section of the outer perimeter of the alignment chamber; wherein the marker deployer tube is insertable into the interior lumen of the biopsy needle such that, when the alignment chamber on the biopsy device and the alignment member on the marker delivery device matingly engage, the side opening of the marker deployer tube will be located within the biopsy needle in substantial alignment with the lateral aperture of the biopsy needle, wherein the marker deployer tube is configured to be received by the alignment chamber.
