Medical Device R&D Company in the Field of Metabolic Diseases
Metabolic Diseasesis the primary cause of suboptimal health status globally, and its prevention and treatment presentSignificant Unmet Clinical Needs. Globally, there are up to 2.2 billion overweight individuals and 700 million obese individuals, with 3.4 million deaths annually attributed to conditions related to obesity or overweight. Obesity has become a major public health issue in China, which now ranks first worldwide in both the incidence rate and growth rate of overweight and obesity, making it the country with the largest number of overweight and obese individuals. It is projected that by 2030, the prevalence of overweight and obesity among Chinese adults will reach 61%.
Since its inception, Tongee Medical has always adhered to the mission of exploring new methods for treating metabolic diseases. Addressing the challenges and pain points in the field of metabolic disease treatment, Tongee MedicalFocused on developing interventional therapies for the digestive tract, along with related medical devices, disease management, and solutions, its gastric bypass stent system is the first globally innovative product approved for market launch., this therapy has opened up new avenues for the treatment of metabolic diseases.
Gastric Bypass Stent SystemAs an innovative therapy, it offers advantages over traditional treatment options, including being minimally invasive, easy to operate, non-damaging to human anatomical structures, easily removable, and reusable for reimplantation. It achieves a conceptual leap from “reducing intake” to “reducing absorption,” pioneers a new therapeutic pathway in the field of weight management, fills the gap between pharmacological weight loss and bariatric surgery, and serves as an important complement to medical weight management, thereby forming“Lifestyle Intervention → Pharmacotherapy → Interventional Therapy → Surgical Procedure” Stepwise ApproachWeight Loss Landscape.
In January this year, the “Gastric Bypass Stent System” produced by Hangzhou Tongee Medical Technology Co., Ltd. (hereinafter referred to as “Tongee Medical”),Approved for the World’s First Class III Medical Device Certificate for Innovative Endoluminal Interventional Treatment of Obesity!The approval of this product marks a significant step forward for China, and indeed the world, in the field of interventional therapy for metabolic diseases. It signifies a shift from an era where overseas technologies led the industry to one where Chinese innovative technologies are emerging on the international stage.Gastric Bypass Stent System: A China-Originated, World-Leading Innovative Technology, this approval not only highlights the continuous enhancement of China’s original R&D capabilities but will also drive technological innovation across the entire Chinese healthcare industry.

The World’s First Class III Innovative Medical Device Registration Certificate for Endoscopic Interventional Treatment of Obesity
NMPA Registration No. 20243130104
1. Designed to conform to human physiological anatomy, it can be deployed within 5–10 minutes during routine painless gastroscopy and easily removed after 3–6 months of implantation, ensuring safety and efficacy.
2. It not only enables rapid weight loss with long-term maintenance of efficacy, but also effectively treats obesity-associated non-alcoholic steatohepatitis (NASH) and type 2 diabetes.
3. Reinsertable; can also be placed preoperatively in conjunction with surgical procedures to improve surgical success rates and reduce the incidence of adverse events.
“Remodeling” Gut Ecology: Multifactorial Synergy in Promoting Weight Loss and Glycemic Control
Chyme remains within the sleeve, while bile and pancreatic juices are outside the sleeve; the two do not come into contact or mix to initiate chemical digestion until the mid-jejunum. The gastric bypass stent system reduces the effective intestinal length available for the initiation of digestion.
After the gastric bypass stent system isolates the small intestine from food stimulation, the exclusion of nutrient contact promotes remodeling of intestinal morphology and mucosal structure, as well as accelerated turnover of gastrointestinal cells.
The gastric bypass stent system enables distal intestinal L cells to have greater exposure to nutrients, thereby efficiently secreting large amounts of peptides such as GLP-1, GLP-2, and PYY, which further suppress appetite and promote glycemic control and weight loss.
Following the implantation of the gastric bypass stent system, a greater amount of bile acids and nutrients enter the distal small intestine, ileocecal segment, and colon, thereby improving the distribution of intestinal probiotics and significantly increasing their proportion.
