›› Obesity Bypass Without Surgery? Our Clinical Trial
Our vision
A reversible and safe therapy for diabetes patients
The historically recent development that the majority of people have sufficient food at their disposal is accompanied by the mass spread of a new group of diseases: metabolic syndrome and obesity in particular.
We would like to offer a reversible therapy for patients who are at an earlier stage of the disease, in which a tube prosthesis is anchored in the stomach and upper small intestine as part of an outpatient gastroscopy.
We want to offer a safe, effective and easy-to-use product that closes the gap between the conservative forms of therapy available to date and irreversible surgery.
Our product
The Trans-Duodenal Barrier
The Trans-Duodenal Barrier is an endoscopically implantable tubular prosthesis made of polyurethane that lines the duodenum and fixes itself to the gastric outlet with two air-filled balloons.
It is inserted during a gastroscopy and removed again after 6 months. Similar to bypass surgery, this improves diabetes and reduces weight.

A Bariatric Bypass Without Surgery?
TDC has developed a tube bypass that can be inserted into the stomach outlet on an outpatient basis during a gastroscopy (under sedation) and left in place for 6 months. The mechanism of action is similar to that of bypass surgery, but it does not require surgery and leaves no permanent changes.
This therapy is particularly suitable for people with type 2 diabetes and obesity. For the clinical trial, we are therefore looking for patients with a BMI > of 30 or higher and poorly controlled HbA1c > of 7.0 or higher.

Early stage investment. Opportunity in a rapidly growing market.
There are already 60 million diabetes patients in the EU alone, 26.1 million patients with fatty liver disease and 81.3 million obesity sufferers – and the trend is rising sharply.
With its product, Trans-Duodenal Concepts closes the gap between surgical and conservative therapy for diabetes, the treatment of fatty liver disease and obesity treatment by combining an innovative endoscopic technique with ultra-thin polyurethane balloons.
Following clinical studies, CE certification and multicenter PM studies, we plan to have the Trans-Duodenal Barrier ready for the market in 2027.
