TSO3 Inc. joined with UCHealth in announcing the first patient procedure in Colorado performed with a duodenoscope sterilized using the STERIZONE® technology. Duodenoscopes are flexible endoscopes used during Endoscopic Retrograde Cholangiopancreatography (ERCP), which is a procedure that enables a physician to examine and take images of a patient's gallbladder, common bile duct, pancreas and liver. The STERIZONE® VP4 Sterilizer is a low-temperature sterilization system that utilizes the dual sterilants of vaporized hydrogen peroxide (H2O2) and ozone (O3) to achieve terminal sterilization of heat and moisture-sensitive medical devices. Its single pre-programmed cycle can sterilize a large number and wide range of compatible devices, creating a cost-effective sterilization process with error-free cycle selection. The device's unique Dynamic Sterilant Delivery System automatically adjusts the quantity of injected sterilant based on the load composition, weight and temperature. This capability removes the guesswork and potential for human error, as there is no need to sort instruments and choose the appropriate cycles as with other machines.
