Cushing burrs are bone cutting and drilling instruments that are used without a power source on a patient's skull and sold under the Medfix International and Stealth Surgical brand names.

Reason: The reason these devices are being withdrawn from the market by Instrumed is that Instrumed did not market these devices prior to September 26, 1976, and therefore, does not meet all FDA requirements to market the devices as "Pre-Amendment" devices.
