ABSTRACT:
A method and apparatus is provided for reducing the danger of cutting into a passage or organ of the body during a surgical procedure by inserting a catheter into the passage or organ, the catheter having interiorly thereof an infrared radiator and employing an infrared detection system that produces a detectable signal indicative of the proximity of an infrared probe to the passage or organ the proximity of the probe to the passage or organ being a function of the approach of the surgical procedure to the passage or organ. The position of the infrared source and the probe may be reversed. Further a system for viewing the sight of the procedure and displaying the body into which the catheter is inserted is provided.
