Channel Medsystems, Inc.: Brand Name: Cerene Cryotherapy Device Product Name: DEVICE, THERMAL ABLATION, ENDOMETRIAL Model/Catalog Number: FGS-7000 Product Description: The Cerene Cryotherapy Device is an endometrial ablation device that uses nitrous oxide (N2O) to freeze and ablate the endometrium to reduce future menstrual bleeding. The device is intended for use by healthcare professionals who have received appropriate training and are familiar with the principles, clinical applications, complications, side effects, and hazards commonly associated with endometrial ablation. The Cerene Device is single use, disposable, and provided sterile. The average procedure time is 7 minutes, with 2.5 minutes of active cryoablation. Ablation is achieved throughout the uterine cavity through the use of cryothermic energy. The cryothermic energy is provided by a liquid-to-gas phase change of N2O. During the 2.5-minute treatment cycle, liquid N2O (originating from a small Cylinder located in the device handle) flows through a delivery line and into an inflow line with multiple jets. This liquid N2O is infused into an ultra-thin polyurethane Liner, where it converts into gas. The gaseous N2O is exhausted through the Exhaust Hose exiting the bottom of the handle. Component: N/A
