AxoTrack Named One of 2012's Best Innovations

AxoTrack needle visualization technology was named one of the world’s best innovations for 2012 by Popular Science.  The device, invented by emergency physician Stephen F. Ridley, MD, combines traditional ultrasound imaging with advanced magnetics.

While it was originally designed to improve the safety and accuracy of placing central venous catheters, the device is now used for a range of needle-guided procedures. Clinicians using the device are provided with real-time updates of needle position that can be visualized as the needle travels through the tissue to its intended target.
