Duodenoscopes Now Sterilized With a Low-Temperature Sterilizer

Grand Forks, N.D. – TSO3 Inc. (TSX: TOS) ("TSO3" or the "Company"), an innovator in sterilization technology for medical devices in healthcare settings, joins with Altru Health System in announcing the landmark U.S. terminal sterilization of long, flexible gastrointestinal endoscopes, like the duodenoscope, using TSO3’s paradigm-shifting STERIZONE® technology.

“Being the inaugural facility to offer terminal sterilization of endoscopes using the TSO3 technology, provides our patients with a level of safety above current best-practice standards in the industry,” says Stacie Avdem, Director of Surgical and Procedural Services at Altru Health System.

“Altru has achieved industry-leading practices with centralization, cleaning verification, and borescope inspection in endoscope reprocessing. The ability to sterilize endoscopes, specifically duodenoscopes, is paramount to achieving our mission of delivering world-class care to the residents of our region. It shows our ongoing investment in and commitment to patient safety,” says Jenni Gibbs, Manager of Central Sterile Department at Altru Health System.

In May, U.S. regulators approved TSO3’s most recent 510(k) submission for the terminal sterilization of multi-channeled flexible endoscopes using the Company’s STERIZONE® VP4 Sterilizer. The new clearance for the STERIZONE® VP4 Sterilizer allows a hospital-like Altru® Health System to terminally sterilize gastrointestinal endoscopes that have dimensions within the cleared intended use.

“Our mission, to provide a sterile device for every patient, is what TSO3 works toward every day,” said R.M. (Ric) Rumble, TSO3’s President, and CEO. “The recent and highly publicized infection outbreaks associated with the use of flexible endoscopes have highlighted the need for innovative approaches to reprocessing of these complex devices. We are pleased to celebrate this major milestone with Altru® and are working with customers in the U.S. and across the world that will soon be sterilizing their endoscopes using our advanced technology.”

According to the U.S. Centers for Disease Control (“CDC”), at least two million Americans are infected with antibiotic-resistant bacteria each year, and more than 23,000 of them die. Included in those statistics are patients who were infected in healthcare settings. One type of antibiotic-resistant infection that was traced to contaminated endoscopes was caused by Carbapenem-resistant Enterobacteriaceae (CRE), a bacteria the CDC has designated as a “superbug”. This superbug has a 50% mortality rate in infected patients.

About the STERIZONE® VP4 Sterilizer

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.

The STERIZONE® VP4 Sterilizer is the only terminal sterilization method that is FDA cleared to sterilize multi-channeled flexible endoscopes (with a maximum of four channels) of up to 3.5 meters in length, such as video colonoscopes, duodenoscopes, and gastroscopes - an industry first for any medical device sterilization process.

The STERIZONE® VP4 Sterilizer is also the only cleared low-temperature sterilizer that can process a mixed load consisting of general instruments, single-channel flexible endoscopes, and single or double channel rigid endoscopes in the same cycle with load weights of up to 75 lb. The ability to run mixed loads significantly reduces labor costs by minimizing the amount of instrument sorting required while maximizing the device turns (more productivity from increased throughput capacity).
