Advances in Vaporized Hydrogen Peroxide Reusable Medical Device Sterilization Cycle Development: Technology Review and Patent Trends.

ABSTRACT: Vaporized hydrogen peroxide (VHP) terminal sterilization is one of the most promising techniques for sterilizing temperature-sensitive medical instruments like endoscopes. This technique requires only electricity and sterilant containers to perform the sterilization process in less than 1 h without any substantial safety concerns for patients, personnel, and the environment. This review studies recent advances and future trends in VHP sterilization cycle development using U.S. patent applications and 510(k) premarket notifications. In this regard, the patents focused on increasing VHP concentration or handling residual moisture are discussed in depth. The expired patents are analyzed to introduce existing unencumbered technologies, and active patents are presented to show the most current novelties and technology trends. In addition, 510(k) premarket notifications are explored to evaluate implemented technologies in US market-leading commercial products.

Project description:Background and objectiveThe current AMS 800 artificial urinary sphincter (AUS) device is designed to simulate the function of the biological urinary sphincter to prevent urinary flow through mucosal coaptation, compression, and pressure transmission. The challenges in designing the AMS 800 device involve not only the mechanical operation of the artificial sphincter device but also producing a device that is effective, safe, and durable for patients in the long term. The following article provides a narrative review regarding the evolution and development of the AMS 800 devices over the years and evaluates the advances in surgical techniques relating to AMS 800 implantation.MethodsAvailable literature pertaining to the AMS 800 device was reviewed from the MEDLINE and EMBASE databases between 1 January 2000 to 31 December 2022. Emphasis is placed on key scientific publications including previous reviews and clinical guidelines relevant to AMS 800 device(s) and surgical techniques.Key content and findingsFrom the engineering point of view, the current AMS 800 device is ingenious and has stood the test of time. The basic design of this modern AUS consists of 3 separate components namely a pressure regulating balloon (PRB), an inflatable cuff, and a control pump. Continued innovations in device design and technology, coupled with refinements in surgical techniques over the past 5 decades have ensured that the AMS 800 device is and remains the standard of care in male stress urinary incontinence. While the long-term AMS 800 efficacy, safety, and durability are well documented, it is not without its limitations and complications. Mechanical and non-mechanical complications can occur especially in high-risk populations (such as in radiated patients) despite strict adherence to surgical principles and manufacturer's guidelines.ConclusionsContinued innovations in device design, technology, and surgical techniques have ensured that the AMS 800 device is an effective and safe treatment for male stress urinary incontinence (SUI). Future directions in the treatment of male SUI likely reside in cellular regenerative therapy and nanotechnology to restore, replace, or simulate the damaged native urinary sphincter.
