Locating of intracorporeal catheters already in place - using impulse generator linked to skin mounted electrodes

Abstract

Abstract A device for the accurate position finding of already innerted intracorporeal catheters plastic heart and vessel catheters produces direct-current impulses which are introduced into the patient by means of electrodes attached to the skin. The location of the catheter tip is then done by means of a commercial E.C.G. machine, such that the electrical potential between the catheter tip and the skin mounted electrode is detected by the E.C.G. machine. The positioning device may also produce various forms of alternating current impulses which allows usage of several electrical fields simultaneously if any one impulse type is transmitted only by specific skin mounted electrodes.
