  • Patent number: 8905943
    Abstract: A biopsy device comprises a probe body, a cannula extending distally from the probe body, a cutter moveable relative to the cannula to sever tissue, and a tissue sample holder coupled with the probe body. The tissue sample holder comprises a rotatable member having a plurality of recesses to receive tissue samples. The rotatable member can be operable to successively index each recess relative to a lumen defined by the cutter.

  • Publication number: 20140194914
    Abstract: A surgical instrument is provided that can comprise and end effector including two jaws and a cutting member configured to move between the jaws. In at least one embodiment, one or both of the jaws may be flexible, such that a jaw is configured to flex when gripping tissue. Further, at least one of the jaws may include a thin cross-sectional area such that the jaw flexes when gripping tissue. Additionally, in at least one embodiment, one or more compression elements may extend from the cutting member and may be configured to cause the jaws to close when the cutting member is advanced. The compression elements may comprise a roller and/or a low-friction material. Moreover, in at least one embodiment, one or both of the jaws may be precurved, away from the cutting member's longitudinal axis. Accordingly, in various embodiments, the overall force required to advance the cutting member and/or close the jaws may be reduced.

  • 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. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. 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.

  • Publication number: 20140031716
    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: 8251916
    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 has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.
