Milestone of 1,000 Cases | Gastric Bypass Stent System: A Chinese Innovation to Solve the Global Weight Loss Challenge

At 5:22 PM on June 20, 2025, chief physician Li Zhen and his team at the Obesity and Metabolic Disease Surgery Center of Zhongnan Hospital of Wuhan University successfully completed the 1,000th implantation of Tongee’s Gastric Bypass Stent System! From the initial breakthrough of "0 to 1" in practice to the current clinical acceleration of "1 to 1,000," this is not only a significant leap forward in numbers, but also a milestone in the transition of China's original intestinal interventional weight loss therapy from exploration to large-scale application.

Behind the Thousand-Case Milestone

Innovation Foundation and Future Blueprint

One thousand cases of implantation is an important cornerstone for market-scale applications, and the accumulation of high-quality, long-term clinical evidence-based data from tens of thousands to even hundreds of thousands of cases is the core of product vitality and market expansion. To this end, Tongee is fully committed to promoting large-scale, long-term follow-up research projects covering multiple centers nationwide and actively preparing for multicenter clinical trials to accelerate the development of the clinical evidence-based system.

Currently, Tongee is accelerating the expansion of indications for Gastric Bypass Stent System, guided by clinical needs, and continuously deepening its interventional value in metabolic diseases. Besides, the company has also developed innovative devices such as gastric balloons and superabsorbent hydrogel, which have completed early-stage research and development and are about to initiate multi-center clinical validation, establishing a precision treatment matrix covering different targets in the digestive tract. Furthermore, DTx, a digital metabolic health management platform developed by Tongee's subsidiary, is deeply integrating artificial intelligence, AI algorithms and chronic disease management, creating a full cycle service of "interventional treatment-data monitoring-health management".

In the future, these rigorous and detailed "Chinese data" and diversified product matrix will also become the core confidence and competitiveness of Tongee to represent "Chinese innovation" in competing for the global 10 billion weight loss market and send a strong message of "Chinese solution" to the world.

Starting from 1,000 Cases

Join Hands with Prtners to Explore New Paths

From 0 to 1,000, what changes is the number, but the original aspiration of "protecting quality of life through technology" remains unchanged; from China to the world, what changes is the scale, but the commitment of "making innovations accessible to the world" remains unchanged. Reaching the thousand-case milestone is no single effort. Behind this lies the unwavering support, sophisticated technology, and invaluable trust from medical centers, experts, scholars, and partners across the country. It is the collective efforts that drives China's original therapies forward.

Looking ahead, achieving the 5,000th and 10,000th cases will be clear and exciting milestones on Tongee's journey. With the rigorously tested clinical value, we will continue to work with global partners to promote China's innovative wisdom to engrave more "Chinese answers" on the global weight loss treatment landscape!
