The Cric-Key™ and Cric-Knife™: A Combined Tube-Introducer and Scalpel-Hook Open Cricothyrotomy System

Spring 2014

Levitan RM. 14(1). 45 - 49. (Journal Article)


The author describes a cricothyrotomy system that consists of two devices that, packaged together, are labeled the Control-Cric™ system. The Cric-Key™ was invented to verify tracheal location during surgical airway procedures- without the need for visualization, aspiration of air, or reliance on clinicians' fine motor skills. The Cric-Knife™ combines a scalpel with an overlying sliding hook to facilitate a smooth transition from membrane incision to hook insertion and tracheal control. In a recent test versus a traditional open technique, this system had a higher success rate and was faster to implement.
