Debiotech - Eksigent
Animas Corporation entered into license and development agreements with the Swiss company, Debiotech, SA for MEMS technology and intellectual property related to next-generation insulin pumps and micro-needles on October 29, 2004. With the agreement, Animas has acquired the exclusive worldwide license to make, use, and sell products utilizing the intellectual property portfolio owned by Debiotech relating to micro-pumps and micro-needles for use related to insulin administration and in-vivo glucose sensing. Included in this portfolio are over 70 granted or issued patents.
The system currently under development is an external pump for subcutaneous injection of insulin for diabetes care. The insulin pump is based on Debiotech's Chronojet micropump chip. The Injection Pump is light and miniaturized and can be directly taped onto the skin. The Injection Pump is operated and programmed through a Remote Control Device.
The ChronojetTM device is the latest generation of Debiotech's micropump programs. This cost-effective performance pumping mechanism has been conceived to be the heart of a new insulin pump for diabetes therapy. A MEMS (Micro-Electro-Mechanical System) approach was adopted focusing on the aspects of miniaturization, safety, reliability and accuracy. The result is a high-performance micropump with a low flow rate range of typically 10 ul/min. Due to the versatility of the technology and the design approach, it should also meet the requirements of a variety of liquid micro-dosing applications wherever high performance is to be guaranteed over the lifetime of the product. The combination of low cost manufacturing and intrinsic reliability allows to use this pump for disposable applications as well as long-term use.
