  • Biopsy device with variable speed cutter advance
    Patent number: 7645240
    Abstract: A biopsy device having a translating and rotating cutter is disclosed. The translational speed of the cutter is varied using a variable pitch member. The variable pitch member can include a shaft having a relatively coarse threaded portion for rapid cutter advance and a relatively finer threaded portion for cutter advance during tissue severing.
    Type: Grant
    Filed: February 13, 2006
    Date of Patent: January 12, 2010
    Assignee: Ethicon Endo-Surgery, Inc
    Inventors: Bennie Thompson, Larry DaPrato
  • Method of operating a biopsy device
    Patent number: 7252641
    Abstract: A biopsy device and method for operating the biopsy device are disclosed. The method of operating the biopsy device can include varying the translational speed of a cutter independently of the speed of a motor driving translation of the cutter. The method can also include providing close loop control of a fluid system, such as a vacuum system, associated with the biopsy device. The method can also include control of a cutter motor including comparing an actual motor current with a predetermined motor current.
