Abstract
Disclosed herein is a system, apparatus and method directed to obtaining first data indicative of a first location within the patient vasculature, obtaining second data that is indicative of a second location within the patient vasculature, performing a confirmation process that includes determining whether the second location corresponds to the first location within a predetermined threshold, and when the second location is determined to correspond to the first location within the predetermined threshold, determining the first location accurately indicates the current location of the distal tip of the medical device. The first modality may be any of a fiber optic modality, a magnetically-based tip location system modality, or an electrocardiogram monitoring system modality and the second data may represent fluctuations of the distal tip of the medical device. The medical device may be an introducer wire, a guidewire, a stylet, a stylet within a needle, a needle, or a catheter.
