  • Patent number: 8442618
    Abstract: A system and method are provided for delivering a medical device on a catheter to a selected position within a lumen of the body. A medical positioning system (MPS) acquires MPS data for points within the lumen using an MPS sensor on the catheter. Each of the points is associated with a three-dimensional coordinate system and an activity state of an organ of the patient. A user interface receives position data for the selected position. The position date is associated with an MPS representation associated with one of the points. A processor determines a plurality of temporal three-dimensional trajectory representations based on the MPS data and corresponding to the respective activity states of the organ. The processor superimposes the temporal three-dimensional trajectory representations on a two-dimensional image according to the activity states of the organ thereby enabling an operator to visually navigate the medical device toward the selected position.

  • Patent number: 8435181
    Abstract: Systems and methods are described for acquiring, processing, and presenting boundaries of a cavity-tissue interface within a region-of-interest in an ultrasound image based upon the strength of signals of ultrasound echoes returning from structures within the region-of-interest. The segmentation of boundaries of cavity shapes occupying the region-of-interest utilizes cost function analysis of pixel sets occupying the cavity-tissue interface. The segmented shapes are further image processed to determine areas and volumes of the organ or structure containing the cavity within the region-of-interest.

  • Patent number: 8409095
    Abstract: A medical device includes a control interface for operating the medical device in a hands-free mode. To control the medical device in a hands-free mode, the control interface includes multiple proximity sensors, each sensor associated with a level of adjustment. For example, a sensor located on a top portion of the medical device is used to increase the level of adjustment. And similarly, a sensor located on a bottom portion of the medical device is used to decrease the level of adjustment. The magnitude of the level of adjustment applied to a parameter of the medical device is controlled based at least in part on the length of time an object remains in proximity to a respective sensor. In one embodiment, the longer the object is held over a respective sensor the more adjustment the control interface will make to the parameter.

  • Patent number: 8406858
    Abstract: Methods and systems for in vivo classification of tissue are disclosed. The tissue is irradiated with light from multiple light sources and light scattered and fluoresced from the tissue is received. Distinct emissions of the sample are identified from the received light. An excitation emission matrix is generated (1002). On-diagonal and off diagonal components of the excitation emission matrix are identified (1004, 1006, 1008). Spectroscopic measures are derived from the excitation emission matrix (1014), and are compared to a database of known spectra (1016) permitting the tissue to be classified as benign or malignant (1018). An optical biopsy needle or an optical probe may be used to contemporaneously classify and sample tissue for pathological confirmation of diagnosis.
