STMicroelectronics of Italy and France exhibited a miniaturized insulin delivery system that incorporates a pump developed by Debiotech of Switzerland and manufactured by ST using the MEMS (Microelectro Mechanical Systems) technology, for the first time at the CEATEC JAPAN 2007 event.
ST had already announced the agreement with Debiotech on strategic cooperation for commercialization of an insulin delivery system used for treatment of diabetics. It will be commercialized as soon as 2008 by Debiotech.
The exhibited miniaturized insulin delivery system is divided into two parts, an insulin pump/tank component and a battery/microcomputer component. The pump/tank component, which is mass produced at low cost by ST using the MEMS technology, is disposable.
The miniaturized pump incorporating the MEMS technology is 6 × 10 × 2 mm, only a quarter of the volume of current pumps. The pump's discharge rate is 150 nL (nanoliter) per stroke, with a variation of ±5%. It can be used continuously for about a week, although the period varies depending on the patient's condition.
Also exhibited for reference were painless needles manufactured adopting the MEMS technology. Although the needles are not directly related to the exhibited system of Debiotech, commercialization of them will substantially reduce the burden on patients, according to the company.
