HbA1c reduction of 1% and sustained long term results
Single reversible intervention,
no daily needles, minimal side effects
Sustained weight loss and lowered blood pressure
The small implanted DIAMOND device detects when eating begins, and automatically sends gentle pulse signals (gastric contractility modulation signals, or GCM) to the stomach muscles. As a result, the DIAMOND restores the physiological synchronization between food intake and natural hormone secretion, and lowers post meal glucose levels.1 Additionally, GCM signals cause an earlier satiation effect resulting in sustained weight loss.2
Over 300 patients have been treated with DIAMOND in clinical trials3, with up to three years observation. The trials have demonstrated that gastric contractility modulation using DIAMOND significantly reduces HbA1c in a durable manner.4,5,6,7 Clinical data has also demonstrated sustained reduction of weight and blood pressure.8,9
DIAMOND is a one-time intervention treatment for patients with type 2 diabetes who are obese and refractory to oral medication. The DIAMOND device is implanted subcutaneously through a fully reversible, minimally invasive laparoscopic procedure in the upper left abdomen and is connected with three leads to the stomach. Using a wireless physician tablet, the device is then configured and checked periodically by the physician or a clinical associate. Apart from weekly wireless charging, the device is maintenance free and allows patients to lead an active lifestyle. Furthermore, no specific diet adaptation is required beyond standard guidelines for diabetic patients.
