A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.

A biopsy system includes a biopsy device operable for taking one or more biopsy samples from a patient and a marker delivery device. The biopsy device includes a body portion having an alignment feature and a hollow biopsy needle extending distally from the body portion. The marker delivery device includes a marker deployer tube and an alignment feature associated with the marker deployer tube. The alignment feature on the marker delivery device is configured to matingly engage with the alignment feature on the biopsy device. A marker delivery device includes a resilient marker guide ramp.
