SonoSite has received FDA clearance for its tracking and guidance technology for peripherally inserted central catheter line procedures, the LumenVu Catheter Guidance System.

The system combines near-infrared technology with a fiber optic stylet--which replaces a traditional guide wire--to allow visualization and tracking of a catheter tip as it moves through a vein, explained Bothell, Wash.-based SonoSite. The system does not rely on a magnetic field, the company added.
