Abstract: A biopsy device includes a probe, a holster, and a probe lock. The probe includes a probe body and a needle extending distally from the probe body. The probe is releasably couplable to the holster. The probe lock includes a lock member configured to move laterally relative to a longitudinal axis defined by the needle to selectively lock the probe to the holster.

Abstract: A biopsy site marker includes a carrier and a marker element. The marker element is disposed within the carrier. The carrier including a first marker material and a second marker material. The first marker material and the second marker material are each configured to expand in the presence of moisture. The first marker material is configured to expand at a rapid rate relative to the second marker material in the presence of moisture.

Abstract: A unitary control module provides features of an ultrasound system and a biopsy system. A lower module positioned near the bottom of the cart may include power supplies, vacuum components, and biopsy controller components, while an upper module positioned near the top of the cart may include a display, user input devices, and an ultrasound controller. The components of the upper module and lower module may be connected via cabling, hoses, or other connections that run within or along a height adjustable channel member that supports the upper module. The ultrasound controller may be configured to serve as a primary processor for rendering a user interface via the display, and handling user inputs. The ultrasound controller is in communication with the biopsy controller, and handles interpreting and converting inputs and outputs from the biopsy controller in order to provide biopsy status and control features via the user interface.
