Patent Images

1. A system creating a 3D image of a lumen of a subject comprising:

  • a) an invasive device for insertion into a lumen of a subject;

    b) a distance determination means incorporated into an insertion end of the invasive device for measuring a distance from the insertion end to the inside wall of the lumen at a plurality of angular locations;

    c) at least one device locating means located in the invasive device;

    d) a tracking means for tracking the device locating means as an operator moves the invasive device in the subject to determine an instantaneous 3D location of the invasive device;

    e) a storage device for storing 3D locations and measured distances for later retrieval;

    f) a display device for providing graphical displays to the operator; and

    g) a signal interpretation device coupled to the distance determination means and storage device for retrieving the stored measured distances and stored 3D locations to create and display on the display device 3D images of lumen according to operator movement of the invasive device.
