About

OTU Medical Inc. designs, manufactures, and commercializes single-use (one-time-use) flexible digital endoscopes and the imaging systems that drive them. Its WiScope product line spans urology, gastroenterology, pulmonology, gynecology, and ENT, led by a ureteroscope that received FDA 510(k) clearance in 2018. The company was incorporated in the U.S. in 2017 and operates from Union City, California alongside affiliated design and manufacturing operations in China that date back to 2000. Its devices carry NMPA Class II registration (2024) and EU CE marking under MDR (2025).

Vertical integration of the single-use endoscope supply chain — the company independently researches and manufactures its own core optoelectronic components through to final system assembly, rather than sourcing imaging modules from third parties.
