  • Patent number: 11564668
    Abstract: A biopsy device includes a body, a needle, a hollow cutter, and a tissue sample holder. The needle extends distally from the body and includes a lateral aperture. The cutter is movable relative to the needle to sever a tissue sample and defines a cutter lumen. The tissue sample holder includes a manifold and an outer cover. The manifold includes a plurality of passages and an indexing portion. Each passage of the plurality of passages is configured to selectively index relative to a proximal end of the hollow cutter. The outer cover includes a resilient member. The resilient member is configured to engage with the indexing portion of the manifold to selectively index a passage of the plurality of passages with the distal end of the hollow cutter.

  • Publication number: 20220354471
    Abstract: An exemplary ultrasound biopsy device includes a probe and a holster. The probe is insertable into the holster to form a completed assembly. To assemble the probe to the holster, the probe is initially slid laterally onto the holster and then slid forward to latch the probe into engagement with the holster. The holster is coupled to a vacuum control module by one or more conduits and a power cable. The conduits and/or power cable may be retracted into the vacuum control module. The probe of the biopsy device includes a blade assembly at the distal end. The blade assembly comprises a blade that snaps onto a nosecone via a pair of resilient notched ends. A frictional fitting needle cover can be inserted over the needle and blade assembly to protect the user from the sharp blade.

  • Patent number: 10258316
    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.

  • Patent number: 10206665
    Abstract: A biopsy device comprises a body, a needle, a cutter, and a valve assembly. The needle extends distally relative to the body. The needle defines a first lumen and a second lumen. The first and second lumens extend along a first and second longitudinal axis, respectively. The needle includes an opening fluidly coupling the first and second lumens. The cutter is translatable relative to the needle. The valve assembly comprises a vent opening and a spool body. The spool body is movable relative to the vent opening between a first and second position. The second lumen is coupled to the vent opening when the spool body is in the first position. The second lumen is sealed relative to the vent opening when the spool body is in the second position. The spool body is configured to transition between the first and second position by translation of the cutter.

  • Publication number: 20180344299
    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.

  • Publication number: 20180333144
    Abstract: A targeting set for use with positioning a biopsy device relative to a patient includes an obturator, a sleeve, and a latching assembly. The obturator includes a seal cap. The sleeve includes a hub and defines a lumen configured to receive the obturator through the hub. The latching assembly includes an actuator arm attached to the seal cap and a catch positioned in the sleeve hub. The actuator arm includes a proximal end and a distal end adapted to mate with the catch. The proximal end of the actuator arm is configured to move radially inwardly to produce a radially outward movement of the distal end of the actuator arm to unlock the sleeve from the obturator.

  • Patent number: RE47148
    Abstract: 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.
