  • Patent number: 6789545
    Abstract: A cryosurgical system adapted for treatment of fibroadenomas within the breast of a patient. The system includes cryoprobes and a control system which operates the cryoprobes to accomplish freezing in two stages, including a high power freeze and a low power freeze.
    Type: Grant
    Filed: October 4, 2002
    Date of Patent: September 14, 2004
    Assignee: Sanarus Medical, Inc.
    Inventors: Peter J. Littrup, Seth A. Stabinsky, Kevin Van Bladel, Lisa Zindel, Glenn Foy
  • Publication number: 20040122325
    Abstract: A method and apparatus are provided for investigating tissue in which acoustic data are derived from scattering a plurality of pulsed spherical or cylindrical acoustic waves from a plurality of transmission elements through the tissue to a plurality of receiving elements. The acoustic data, which include a mix of reflected and transmitted acoustic waves, are received and digitized, and a representation of a portion of the tissue is generated from the digitized acoustic data.

  • Publication number: 20040122304
    Abstract: A method and system for examining tissue are provided in which the tissue is maintained in a position so that it may be insonified with a plurality of pulsed spherical or cylindrical acoustic waves. The insonifying acoustic waves are scattered by the tissue so that scattered acoustic radiation including a mix of reflected and transmitted acoustic waves is received. A representation of a portion of the tissue is then derived from the received scattered acoustic radiation.

  • Patent number: 6728567
    Abstract: The present invention relates to a method and apparatus for the construction and/or use of multidimensional fields that can be used for high-resolution detection and characterization of features within objects. The multidimensional field is constructed from data that is collected by an array of radiation detectors that substantially surround the object under study. The detected radiation is produced by an array of radiation sources and is subsequently scattered, reflected, transmitted, or diffracted by the object under study and any features within the object under study. In particular embodiments of the invention, the radiation that is used is ultrasonic radiation and the object under study is human or animal tissue or an organ. In this case, the invention permits the detection and identification of cancer by an intelligently trained evaluation system.

  • Publication number: 20040030227
    Abstract: A method for treating a medical pathology includes receiving a first set of acoustic radiation scattered by a volume of tissue containing at least a portion of the medical pathology and thereafter, changing a temperature of the volume of tissue. The method also includes thereafter, receiving a second set of acoustic radiation scattered by the volume of tissue and localizing the portion of the medical pathology from the first and second sets of received acoustic radiation. Localizing the portion of the medical pathology comprises identifying the medical pathology from differences in the first and second sets of received acoustic radiation resulting from the change in temperature. The method also includes insonifying the portion of the medical pathology with sufficient energy to damage the portion of the medical pathology.
