Abstract: Tip confirmation systems and related methods are disclosed. A method of determining one or more properties of a catheter in a patient comprises advancing a catheter in vasculature of a patient, the catheter coupled to at least one radiation source and at least one detector, transmitting source electromagnetic radiation from the at least one radiation source out of the catheter proximate a distal tip thereof, measuring an intensity of backscattered electromagnetic radiation from the at least one radiation source with the at least one detector, and providing a signal indicative of a location of the distal tip within the vasculature based, at least in part, on the measured intensity of the backscattered electromagnetic radiation. Related systems and methods are also disclosed.
