  • Patent number: 9095326
    Abstract: A biopsy system includes a biopsy device having a translating cutter for severing tissue samples and a vacuum control module. The vacuum control module is separate from the biopsy device. The vacuum control module includes a vacuum pump and vacuum canister, and is portable by a single hand. The vacuum canister and the vacuum control module have complimentary ports that are configured to couple upon insertion of the vacuum canister into the vacuum control module. The complimentary ports provide fluid communication between a vacuum pump in the vacuum control module and a reservoir in the vacuum canister. The biopsy device may be placed in fluid communication with the vacuum pump via the canister without the user having to separately connect any tubes with the canister or pump.

  • Patent number: 9039634
    Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each of the chambers with the cutter lumen. A sensing system is configured to sense the rotational position of the manifold. A controller in communication with both the sensing system and the rotation mechanism is operable to control the rotation mechanism based at least in part on the position of the manifold as sensed by the sensing system. The sensing system may include a sensor in a fixed position and a rotating encoder wheel on a shaft that is used to rotate the manifold.

  • Patent number: 9005136
    Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.

  • Patent number: 8979769
    Abstract: A biopsy device includes an elongate needle, a proximal portion, a cutter, and a vacuum conduit. The elongate needle defines an internal passage and includes a distal end and a first plurality of openings along an exterior surface of the elongate needle in communication with the internal passage. The first plurality of openings are sized to admit fluid and to resist the prolapse of tissue. The proximal portion is attached to the elongate needle and is positionable to insert the elongate needle into tissue. The cutter is reciprocally received by the elongate needle to sever a tissue sample received in the elongate needle. The cutter includes a cutter tube with a second plurality of openings in communication with the internal passage of the elongate needle. The vacuum conduit is attached to the proximal portion in communication with the internal passage and is coupled to a vacuum source.

  • Publication number: 20150065913
    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: 20140358027
    Abstract: A tissue sample holder for a biopsy device comprises an outer cup, a collection tray, and a flow restriction device. The outer cup defines a hollow interior. The collection tray separates the hollow interior into an upper chamber and a lower chamber while allowing fluid to pass between the two chambers through an opening in the collection tray. The flow restriction device selectively seals the opening thereby preventing fluid from passing from the lower chamber into the upper chamber. The flow restriction device may be operable to selectively seal the opening in response to a vacuum being induced within the upper chamber. The collection tray may have a shape (e.g., tapered, funnel-shaped, convex, etc.) selected to facilitate the flow of fluid toward the opening. The lower chamber may be coupled with an external fluid collection device. The lower chamber may define a larger volume than the upper chamber.

  • Publication number: 20140275999
    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: 20140100478
    Abstract: A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces.

Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.
