ABSTRACT:
A method and apparatus for guiding a physician in the placement of a probe in the body. The method of placement of a catheter or probe in the body through a multi-directional walled path departing from a straight line involving inserting an insulated catheter or probe with a distal uninsulated tip which is electronically connected in a circuit to an electronic catheter guidance system apparatus located outside the patients body which has a power source and a calibrated monitor. The catheter is advanced by a physician into an initial opening in said multi-directional path in a patient's body moving the tip of said catheter or probe forward along said path until the calibrated monitor displays that an obstruction has been met indicating a change in path direction. Using this information the physician halts or discontinues or slows down in the forward movement of said catheter or probe until an adjustment is made such as by twisting or turning or externally pushing the contacting wall so that forward movement of the catheter or probe may be continued without obstruction as determined by the information provided by the electronic catheter guidance system display. The physician repeats such steps as the calibrated monitor displays that the catheter tip is within the desired walled path and that the catheter may be utilized.
