A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.

An in-vivo sensing system and a method for creating a summarized graphical presentation of a data stream captured in-vivo. The graphical presentation may be in the form of a series of summarized data points, for example a color bar. The color bar may be a fixed display along side a streaming display of the data stream. A cursor, icon or other indicator may move along the fixed color bar as the data stream is displayed and / or streamed so as to indicate to a health professional what part of the data stream may be currently displayed. The color content in the color bat may map out the data stream and give indication of the location of anatomical sites as well as possible locations of pathology.
