  • Patent number: 8452375
    Abstract: Systems and methods for locating and defining a target location within a human body. The system can include at least one marker, a probe, and a detector for use in locating the markers by providing information to a surgeon that is representative of changes in proximity between the probe and the marker. The marker can have various detection characteristics, e.g., gamma radiation, that are detectable by an associated probe and detector. The tissue volume is removed by manipulating a cutting tool based on the proximity information provided by the detector, which can be used by the surgeon to define the boundary of the tissue volume. The systems and methods of the invention are particularly useful in locating and then removing a tissue volume or other target location from amorphous, pliable tissue (e.g., breast tissue) or other body parts.

  • Publication number: 20100137713
    Abstract: Systems and methods for stabilizing a target location within a human body. One embodiment of the system provides a tissue anchor for holding a tissue mass within a human body. The tissue anchor may include a lead; a tissue fastener coupled to the lead; and a marker which can be detected by a position detection system to facilitate placement of the anchor. The tissue anchor can be used to help stabilize tissue in a surgical procedure, e.g., in excising a lesion in amorphous, pliable tissue (e.g., breast tissue) or other body parts.

  • Publication number: 20060276379
    Abstract: The invention provides methods and compositions for diagnosing and treating subjects using EBPs. Specifically disclosed are peptides and peptidomimetics that bind selectively to the extracellular domain of ErbB2. These compositions are useful in the prevention and treatment of disorders characterized by ErbB2 overexpression (e.g., breast cancer).

  • Publication number: 20050059884
    Abstract: A system and method for bracketing a tissue volume (22) and later locating the bracketed tissue volume. The system includes a plurality of markers (30) and a probe (32) and detector (34) for use in locating the markers by providing information usable by a surgeon that is representative of changes in proximity between the probe and the plurality of markers. The markers have various detection characteristics, e.g., they transmit gamma rays, that are detectable by an associated probe and detector. The tissue volume is removed by manipulating a cutting tool based on the proximity information provided by the detector which can be used by the surgeon to define the boundary of the tissue volume. A two-part cutting tool (200) is provided for removing the tissue volume, and a tissue anchor (300) is provided for stabilizing the tissue during removal. The system and method of the invention are particularly useful in bracketing and then removing a tissue volume from amorphous, pliable tissue such as breast tissue.

  • Patent number: 6500119
    Abstract: An apparatus obtains image data for a structure through bodily tissue. The apparatus includes an imaging sensor that contacts the bodily tissue to obtain image data for a first image of the structure. A pressure sensor is oriented in substantially a same direction as the imaging sensor and contacts the bodily tissue to obtain data for a second image of the structure. The second image is a different perspective of the structure than the first image.
