Endovascular navigation system and method
First Claim
1. An endovascular navigation system, comprising:
- an elongate flexible member configured to access the venous vasculature of a patient;
a sensor disposed at a distal end of the elongate flexible member and configured to sense a physiological signal of the venous vasculature of the patient;
a processor configured to;
receive the physiological signal of the venous vasculature of the patient provided by the sensor;
process the physiological signal to determine one or more physiological characteristics of the venous vasculature of the patient;
track a position of the distal end of the elongate flexible member within the venous vasculature of the patient over time; and
determine, based on the one or more physiological characteristics of the venous vasculature of the patient, that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature of the patient;
a display output device configured to simultaneously display;
a graphical representation of a path between tracked positions of the distal end of the elongate flexible member within the venous vasculature of the patient over time;
a first visual indication of the position of the distal end of the elongate flexible member in real time;
at least part of the physiological signal provided by the sensor over time; and
a second visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient only when it is determined that the position of the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, wherein the second visual indication is different from the physiological characteristic of the venous vasculature of the patient, and the graphical representation is different from the at least part of the physiological signal and the second visual indication; and
an audible output device configured to output an audible indication of the position of the distal end of the elongate flexible member.

Abstract
The endovascular navigation system includes an elongate flexible member configured to access the venous vasculature of a patient, a sensor disposed at a distal end of the elongate flexible member and configured to sense a physiological characteristic of the venous vasculature, a processor and an output device. The processor is configured to receive and process the physiological characteristic of the venous vasculature, and to determine that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature. The output device is configured to display a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature, where the visual indication is different from the physiological characteristic of the venous vasculature of the patient.
