Equipment and methods for navigation, evaluation and / or diagnosis of blood vessels

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for performing navigation, evaluation and / or diagnosis of a blood vessel. When the introduction of a medium with measurable parameters (eg, temperature, light reflection, sound reflection, etc.) is used to locate the tip of a vascular catheter 2508 and the catheter is advanced. , Sensing and measuring measurable parameters. Parameter measurements are tracked, recorded and analyzed over time. Parameter values and / or shape-to-time curves of the parameter values can be used in the analysis. For example, curve amplitude, variability, standard deviation, tilt, etc. can be used in the analysis of catheter location. [Selection diagram] FIG. 39A
