About

This study aims to analyze the pre- and post-operative clinical, hormonal and biochemical changes in moderately obese type 2 diabetic patients who are sub-optimally controlled on at least 2 anti-diabetic agents. Study participants will either receive implantation of the gastric contraction modulator or conventional treatment with insulin therapy.

24 participants in 2 patient groups

Tantalus
Experimental group
Description:
The TANTALUS System is implanted using minimally invasive procedure (laparoscopy). It uses leads with stitch electrodes to deliver electrical signals to the gastric wall for the treatment of obese subjects with T2DM. The device is intended to improve glycemic control and induce weight loss.
Treatment:
Device: Tantalus
Control
Active Comparator group
Description:
Insulin treatment will be prescribed, in accordance with the common medical practice at the institute. Dosages will be recorded on a daily basis.
Treatment:
Drug: Insulin
