Integrated system for intravascular placement of a catheter
First Claim
1. A catheter placement system for inserting a catheter into a vasculature of a patient, comprising:
- a console;
a stylet removably positionable within a lumen of the catheter, the stylet including;
a magnetic assembly for producing a magnetic field;
an ECG sensor assembly for detecting ECG signals of a node of a heart of the patient, including an electrically conductive core wire; and
a first connector in operable communication with the core wire of the ECG sensor assembly, the first connector including a pin contact in operable communication with the core wire, the pin contact disposed in a channel defined in the first connector;
a tip location sensor positionable on a chest of a patient, the tip location sensor configured to detect a magnetic field of the magnetic assembly when the catheter is disposed within the vasculature of the patient;
a second connector included with the tip location sensor for operably connecting to the first connector of the stylet to enable the ECG signals detected by the ECG sensor assembly to be communicated to the tip location sensor, wherein the first and second connectors are physically connected via a perforation defined in a drape interposed between the stylet and the tip location sensor positionable on the chest of the patient, the physical connection of the first and second connectors producing the perforation in the drape and confining the perforation so as to prevent a compromise of a sterile field of the patient; and
a display for displaying information relating to at least one aspect of the ECG signal detected by the ECG sensor assembly.

Abstract
An integrated catheter placement system for accurately placing a catheter within a patient'"'"'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.
