The MAYFIELD¿ Ultra 360 Base Unit for head positioner, one unit per package. Product Usage: This product provides the ability to position and hold a patient head while the patient is in the prone, supine, lateral or park-bench and sitting positions. It is intended to be used during diagnostic examinations or surgical procedures where a rigid support between the surgical table and a headrest or skull clamp is necessary and positional freedom is required.

Reason: Through an investigation of complaints, Integra found that there is the possibility for the locking handle mechanism of the Base Units to fail during use.
