Systems and Methods for Guidance and Placement of an Intravascular Device

摘要

A guidance and placement system and associated methods for assisting a clinician in the placement of a catheter or other medical device within the vasculature of a patient is disclosed. In one embodiment, a method for guiding a medical device to a desired location within a vasculature of a patient is also disclosed and comprises detecting an intravascular ECG signal of the patient and identifying a P-wave of a waveform of the intravascular ECG signal, wherein the P-wave varies according to proximity of the medical device to the desired location. The method further comprises determining whether the identified P-wave is elevated, determining a deflection value of the identified P-wave when the identified P-wave is elevated, and reporting information relating to a location of the medical device within the patient's vasculature at least partially according to the determined deflection value of the elevated P-wave.

1. A method for guiding a medical device to a desired location within a vasculature of a patient, the method comprising:
detecting an intravascular ECG signal of the patient; identifying a P-wave of a waveform of the intravascular ECG signal, the P-wave varying according to proximity of the medical device to the desired location; determining whether the identified P-wave is elevated; determining a deflection value of the identified P-wave when the identified P-wave is elevated; and reporting information relating to a location of the medical device within the vasculature of the patient at least partially according to the determined deflection value of the elevated P-wave.
