Abstract
The present invention is a system comprising an illumination means and is mounted on a catheter wherein said illumination is generally located in the distal end of the catheter. Locating the illumination means near the distal end will simplify and facilitate precise placement of a measurement device in close proximity to the desired location. In one example, a catheter with a distally mounted pH sensor benefits from the use of an illumination means in the patient's airway such as in the oropharynx region. The illumination source of the present invention addresses catheter insertion and location using a continuous or flashing light emitting diode (LED) embedded in the distal end of the catheter to provide a visual sighting means for the physician. When the catheter, with the illumination means is inserted in the patient's airway, the illumination means functions to illuminate the distal end of the catheter and the anatomical features of the patient's airway for observation by the clinician, thereby facilitating proper placement of the measurement device.
