Integrated system for intravascular placement of a catheter
First Claim
1. A catheter placement system for positioning a catheter in a vasculature of a patient using at least two different modalities, comprising:
- a console, including a display;
a stylet removably positionable within a lumen of the catheter, the stylet including;
a magnetic assembly configured to produce a magnetic field;
an electrocardiogram (ECG) sensor assembly for detecting ECG signals of a node of a heart of the patient; and
a first connector in communication with the ECG sensor assembly;
a tip location sensor positionable on a chest of the patient, the tip location sensor configured to detect the magnetic field of the magnetic assembly when the catheter is disposed within the vasculature of the patient, the magnetic field providing magnetic field information for locating the magnetic assembly relative to the tip location sensor, the tip location sensor configured to communicate the magnetic field information to the console;
a second connector included with one of the tip location sensor and the console, the second connector configured to connect to the first connector of the stylet to enable the ECG signals detected by the ECG sensor assembly to be communicated to at least one of the tip location sensor and the console; and
an external electrode configured to be placed on an external portion of the patient, the external electrode coupled to the second connector,wherein the console is configured to receive the magnetic field information and at least one aspect of the ECG signal detected by the ECG sensor assembly, the at least one aspect of the ECG signal indicative of proximity of the ECG sensor assembly to the node, and configured to show a graphical representation of the magnetic assembly and the at least one aspect of the ECG signal, including an ECG waveform, on the display.

Abstract
An integrated catheter placement system for accurately placing a catheter within a patient'"'"'s vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient'"'"'s chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to intravascular introduction of the catheter. The ultrasound probe includes user input controls for controlling use of the ultrasound probe in an ultrasound mode and use of the tip location sensor in a tip location mode. In another embodiment, ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient'"'"'s heart.
