Abstract: A biopsy device includes a body, a needle, a cutter, an analysis area, a valve, and a tissue sample holder. The cutter is movable relative to the needle and in communication with the needle for transporting tissue samples. The analysis area is disposed proximally of the cutter and in communication with the needle to receive a tissue sample cut by the cutter for analysis by a user. The valve is disposed proximally of the analysis area and configured to alternate between an open configuration and a closed configuration. The tissue sample holder is disposed proximally of the valve and fixedly attached to the body. The valve is configured to permit analysis of the sample disposed in the analysis area when the valve is in the closed configuration and to permit the tissue sample to be passed into the tissue sample holder when the valve is in the open configuration.

Abstract: An apparatus includes a needle, a cutter, a medication fluid path, and a filter assembly. The needle defines a tissue receiving feature. The cutter is movable relative to the needle to sever tissue protruding into the tissue receiving feature. The medication fluid path includes a first portion and a second portion. The first portion is configured to couple with a source of medication fluid. The tissue receiving feature is in fluid communication with the medication fluid path such that the first portion is upstream of the tissue receiving feature. The filter assembly is located in the second portion of the medication fluid path. The filter assembly is configured to permit air to pass through the filter assembly. The filter assembly is further configured to prevent medication fluid from passing through the filter assembly.

Abstract: A marker delivery device, “adaptor”, for a MRI breast biopsy system is described and claimed. The marker adaptor for the MRI breast biopsy device provides the operator with the ability to easily mark after an MRI biopsy procedure through the biopsy sleeve. The flexible shaft marker snaps into the marking adaptor which creates the oval shape that mates with the inner surface of the sleeve. This locks the orientation of the sleeve and marker, with adaptor, together. The marker adaptor also contains a hard-stop which allows the user to place the biopsy marker in the correct location.

Abstract: A biopsy system, including a biopsy device, a localization assembly, and a control module. The localization assembly is configured to orient the biopsy device relative to a patient. The control module is communication with the biopsy device. The control module is configured to operate a plurality of functional features of the biopsy device. The control module includes a cable and a cable management assembly. The cable management assembly includes a pair of cable management plates, and a weight. Each of the pair cable management plates are disposed substantially parallel to each other and define a space therebetween. The weight is configured to move within the space defined by the pair of cable management plates. The weight is attachable to the cable of the control module and is further configured to slide axially along the cable.

Abstract: A targeting set for use with positioning a biopsy needle relative to a patient. The targeting set includes an obturator, a side notch, and a neck. The obturator includes an elongate shaft extending between a distal tip and a hub. The side notch is defined by the elongate shaft and is configured to receive tissue for visualization under MRI. The neck is defined by the elongate shaft and disposed proximate of the side notch. The neck has a tapered portion tapering radially inwardly towards the distal tip.

Abstract: A biopsy device comprises a probe body, a needle portion, a hollow cutter, and a tissue sample holder. The needle portion extends distally from the probe body and comprises a transverse tissue receiving aperture. The hollow cutter is translatable relative to the needle portion to sever a tissue sample from tissue protruding though the aperture. The hollow cutter defines a cutter lumen. The tissue sample holder comprises a body and a tissue sample tray. The tissue sample tray is removably engaged with the body and comprises a downwardly extending lumen. The downwardly extending lumen includes a pair of lower openings which are in communication with a chamber defined by the tissue sample tray.

Abstract: An apparatus for use with a biopsy device to position a needle of the biopsy device within breast tissue is described and claimed. The apparatus includes a cannula, an obturator; and an obturator actuation assembly, which is described as an “overshoot obturator”. The overshoot obturator is designed to give the physician the ability to set the z-lock to the targeted depth, then move the obturator forward, relative to the sleeve to cut additional tissue. This reduces the tissue force which can push the obturator out of the desired biopsy location.
