PretzelFlex™ was the world’s first pretzel shaped organ and tissue retractor designed for use in Minimally Invasive Surgery.

This fully reusable concept allows the actuation of the device to begin before all of the segments have entered the body, minimizing the space required for retraction through its ‘Advance and Actuate’ SmartFlex™ technology.

Complemented by our FastClamp™ system, the surgical retraction system can be held securely in position during long periods of surgery without the need for human intervention.
