  • Publication number: 20180140286
    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.

  • Patent number: 9877706
    Abstract: A biopsy device includes a probe, a holster, and a tissue sample holder for collecting tissue samples. The probe includes a needle and a hollow cutter. The tissue sample holder includes a housing having a plurality of chambers that are configured to receive a plurality of strips connected by at least one flexible member. The flexible member is configured to permit the strips to pivot relative to each other such that the strips can shift between a flat configuration and a arcuate configuration. The tissue sample holder is rotatable to successively index each chamber to the cutter lumen such that tissue samples may be collected in the strips. The strips may be removed from the tissue sample holder and placed in a tissue sample holder container for imaging of tissue samples.

  • Publication number: 20160324509
    Abstract: A biopsy system comprises an introducer, a biopsy device having a needle, and a marker applier. The introducer may include a closed distal tip, a lateral aperture, a proximally facing interior wall, and a ramp that guides the closed distal end of a marker applier up and into abutment with the wall as the applier is fed into the introducer. The needle of the biopsy device includes a blunt distal end and features providing clearance for the ramp as the blunt distal end is brought into abutment with the wall when the needle is fed into the introducer. The introducer may alternatively include an open distal end having resiliently biased leaves that bear against an inserted biopsy device needle. In some other versions, a fin projects laterally from the closed distal end of a marker applier, spacing the distal end away from a sidewall region of the introducer cannula.
