Apparatus and method for performing navigation, evaluation and / or diagnosis of blood vessels

摘要

Devices and methods for performing navigation, evaluation and / or diagnosis of blood vessels have been described, using the introduction of media with measurable parameters (eg, temperature, light reflection, sound reflection, etc.) Determine the location of the tip of the vascular catheter and sense and measure measurable parameters as the catheter is advanced. Parameter measurements are tracked, recorded and analyzed over time. Parameter values and / or parameter value shape vs. time curves may be used in the analysis. For example, curve amplitude, variability, standard deviation, slope, etc. can be used in the analysis of the catheter location.
