  • Patent number: 8454531
    Abstract: A vacuum control module for use in a biopsy system includes a user interface that presents buttons and icons to control operation of a biopsy device. The icons may indicate, e.g., the position of a cutter relative to a transverse opening, whether the system is in a view sample mode, that an adjacent button is operable to reset the position of a rotatable tissue sample holder, whether the system is in a maintenance vacuum pulse mode, the level of vacuum provided by a vacuum source, the volume level of a speaker, that an adjacent button is operable to place the system in a standby mode, and that an adjacent button is operable to shut down the system. The icons may each have an associated button. The icons may be allocated among separate pages (e.g., a probe page and a system page). Another button may be used to switch between pages.

  • Publication number: 20060258956
    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.
