The Codman EDS 3 CSF External Drainage System was developed with input from more than 200 nurses and physicians. The clinicians who work every day with CSF drains inspired solutions that distinguish the Codman EDS 3: ease-of-use in an integrated pole clamp and accurate hydrostatic leveling from a unique laser leveling device. The EDS 3 provides all this, plus upgraded stopcocks, pressure-resistant tubing, and a multi-functional drip chamber - all in a fully MRI conditional design.
