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 characteristic of the venous vasculature of the patient;
a processor configured to;
receive and process the physiological characteristic of the venous vasculature of the patient provided by the sensor;
determine, based on the processing of the physiological characteristic 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; and
an output device configured to display, in response to the determination that the position of the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient,wherein the visual indication is different from the physiological characteristic of the venous vasculature of the patient.

Abstract
An endovascular navigation system and method are disclosed. 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 of the patient, a processor and an output device. The processor is configured to receive and process the physiological characteristic of the venous vasculature of the patient, and to determine that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature of the patient. 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 of the patient, where the visual indication is different from the physiological characteristic of the venous vasculature of the patient.

20. An endovascular navigation method, comprising:
-
receiving a physiological characteristic of a venous vasculature of a patient provided from a sensor on a distal end of an elongate flexible member within the venous vasculature of the patient; processing the physiological characteristic of the venous vasculature of the patient received from the sensor; determining, based on the processing of the physiological characteristic 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; and displaying, in response to the determination that the position of the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, wherein the visual indication is different from the physiological characteristic of the venous vasculature of the patient.
