Abstract: A biopsy device comprises a probe and a holster. The probe has a distally extending needle including a transverse tissue receiving aperture. A cutter is translatable relative to the needle to sever tissue protruding through the aperture. A thumbwheel is manually operable to rotate the needle to reorient the angular position of the aperture about the longitudinal axis defined by the needle. The thumbwheel is positioned obliquely with the longitudinal axis. A cable driven mechanism in the holster drives the cutter. A rotatable tissue sample holder is coupled with the probe, and has chambers configured to receive tissue samples communicated proximally through a lumen defined by the cutter. A piezoelectric motor in the holster drives the tissue sample holder.

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.

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.

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 respectively configured to receive a tray. The housing is releasably engageable with the probe. Each tray is configured to receive a tissue sample communicated through the cutter lumen. Each tray is removable from the housing, such as along an axial direction. The tissue sample holder is rotatable to successively index each chamber to the cutter lumen. A tray retainer is operable to selectively secure the trays relative to the housing. The trays may be flexible, resilient, or rigid.

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.

Abstract: A biopsy device targeting set includes a vertical member, a carriage that is vertically movable along the vertical member, and a cradle coupled with the carriage. The cradle has a pair of substantially perpendicular mounting arms. Each mounting arm has a recess that may receive a rail of the carriage, such that the cradle may be mounted to the same rail in different orientations. Each mounting arm also has a biopsy device mounting feature, which may be a recess or a rail. The biopsy device mounting feature is configured to engage with a complementary feature of a biopsy device, such that a biopsy device may be mounted to either mounting arm. A z-stop feature is operable to selectively restrict longitudinal motion along either or both of the biopsy device mounting features. The targeting set may be used with a biopsy device in an MRI environment.
