Brief Summary

Approval study Trans-Duodenal Barrier The goal of this clinical trial is to determin the safety and performance of the newly developed Trans-Duodenal Barrier in adult Tryp 2 diabetic and obese patients. The Trans-Duodenal Barrier is an endoscopic implant which can be placed to the gastric outlet and the upper small bowel by interventional endoscopy. It consists of a 60 cm long foil tube , a transpyloric shaft and and two ringlike balloons to fix it at the pylorus. It will be removed after 6 months via gastroscopy. The main questions it aims to answer are:

  • Does the Trans-Duodenal Barrier lower the HbA1c of the participants ?
  • How frequent are adverse side effects related to the device?
  • How much ist the excessive wight loss of treated patients ?
  • Show patients with Metabolic assiociated Hepatosteatitis (MASH) improvements in liver elasticity (elastography) ? Researchers implant the Trans-Duodenal Barrier to enclosed patients and follow up them till 4 weeks after explantation. Participants will:
  • Get the Trans-Duodenal Barrier as an implant for 6 moths
  • Visit the clinic 3 times in the implant period and once for explant.
  • Receive a telefon interview 4 weeks after explant

Study Arms (1)

Treatment with endoscopic implant of the investigational device

EXPERIMENTAL

The decive will be implanted under sedation with the help of a standard flexible gastroscope. By filling the ringlike ballons with 62 ccm saline solution it will be fixed at the gastric oulet. After 6 months it will be removed by puncture and evacuation of the ballons and removal with a standard foreighn body forceps.

Device: endoscopic implant

Interventions

The implant will be placed under sedation with the help of an standard flexible gastroscope. It will be fixed by fluid injection into ringlike ballons and place the device at the gastric outlet. After 6 months it will be removed by punction and evacuation of the ballons and extraction with a standard endoscopy foreighn body grasper.

Also known as: gastroduodenal bypass liner
