Standard Ultrasound Guidance vs. New Needle-steering Device in Subclavian Venous Catheterization

"1. Navigation software is implemented in an ultrasound machine.~2. A linear ultrasound probe (similar in appearance to a standard ultrasound probe) is used~3. Magnetization of the puncture needle after short introduction of the needle in a dedicated device.~4. Real time needle guidance on the ultrasound screen during the puncture."
