Apparatus and method for catheter navigation using indovascular energy mapping

Abstract

Devices and methods for obtaining and using endovascular electrograms in a number of clinical applications and settings are disclosed. In one embodiment, a method is disclosed for locating an indwelling medical device within a vasculature of a patient. The method comprises identifying an endovascular ECG waveform complex from an endovascular ECG signal associated with the indwelling medical device, then calculating an absolute value of the energy of the endovascular ECG waveform complex over a predetermined segment thereof. A position of the medical device within the vasculature is then determined by observation of the absolute value of the energy of the predetermined segment of the endovascular ECG waveform complex.

AI Technical Summary

Problems solved by technology

However, remote monitoring of heart disease is not as widely accepted as it is expected to be and possible

One reason involves the relative complexity of acquiring signals related to cardiac activity, specifically ECG signals

Another significant limitation of current remote monitoring technologies is the use of communication channels that are difficult to interface at both the patient and physician levels, such as telephone lines
