Integrated System for Intravascular Placement of a Catheter
First Claim
1. An integrated catheter placement system for placing a catheter in a vasculature of a patient, comprising:
- a system console;
a tip location sensor configured for temporary placement on a portion of a body of the patient, the tip location sensor configured for sensing a magnetic field of a stylet disposed in a lumen of the catheter when a distal portion of the catheter is disposed in the vasculature, the tip location sensor being operably connected to the system console; and
an ultrasound probe for ultrasonically imaging an internal portion of the patient prior to introduction of the catheter into the vasculature, the ultrasound probe operably connected to the console, the ultrasound probe including 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.

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.
