  • Patent number: 9504453
    Abstract: A magnetic resonance imaging (MRI) compatible core biopsy system uses a biopsy device having intuitive graphical displays and a detachable remote keypad that advantageously allows convenient control even within the close confines afforded by a localization fixture installed within a breast coil that localizes a patient's breast and guides a probe of the biopsy device relative to the localized breast. A control module for interactive control and power generation are remotely positioned and communicate and transmit rotational mechanical energy via sheathed cable.

  • Publication number: 20090131821
    Abstract: A biopsy system includes a vacuum control module, a cannula with a transverse opening, a cutter within the cannula, and a rotatable tissue sample holder. The vacuum control module includes a speaker, a vacuum source, and a graphical user interface for controlling the biopsy system. The graphical user interface includes a display and capacitive switches that serve as buttons. The graphical user interface is operable to perform, e.g., the following functions: varying the position of the cutter relative to the transverse opening, activating a view sample mode, resetting the position of the rotatable tissue sample holder, activating a maintenance vacuum pulse mode, varying the level of vacuum provided by the source of vacuum, varying the level of volume of sounds emitted by the speaker, selectively placing the biopsy system in a standby mode, and selectively shutting the biopsy system down.
