The NGage Nitinol Stone Extractor, manufactured by Cook Medical, represents an entirely new category in the evolution of stone extraction. Utilizing the revolutionary nitinol technology, NGage allows physicians to easily engage, release and extract stones even in the most difficult anatomy while providing improved irrigation, visibility and enhanced efficiency. In recent clinical evaluations, the breakthrough NGage proved more effective than standard devices in grasping and holding fragments in the kidney and urinary tract. Its retention strength was also demonstrated to be 1.5 times stronger than traditional graspers.
