Apparatus and method for endovascular device guiding and positioning using physiological parameters

An endovascular device, comprising:

• an elongate body with a proximal end and a distal end;
• a non-imaging ultrasound transducer on the elongate body;
• an endovascular electrogram lead on the elongate body in a position that, when the endovascular device is in the vasculature, the endovascular electrogram lead is in contact with blood;
• a processor configured to receive and process a signal from the non-imaging ultrasound transducer and a signal from the endovascular electrogram lead;
• and
• a memory for storing instructions which, when executed by the processor, causes the processor to:
• calculate one or more blood flow features extracted from the non-imaging ultrasound signal, wherein the one or more blood flow features includes a ratio of a blood flow power spectrum away from the ultrasound transducer and a blood flow power spectrum towards the ultrasound transducer;
• calculate one or more electrogram features extracted from the electrogram signal, wherein the one or more electrogram features includes a P-wave amplitude;
• and
• determine a position of the elongate body within the vasculature based on the calculated one or more blood flow features and one or more electrogram features.
