Abstract

One example of the SFB 516 transfer work is a bistable microvalve which is planned to be integrated in implantable high precision dose infusion pumps typically used for patients with chronic pain or spasticity. The drug pumps are designed to have a 35 year lifespan within the patients body and work without an external energy supply. To adjust the drug rate to the individual needs of the patient, it is of utmost importance to provide a variable drug output rate. To achieve this goal, an innovative low-energy microvalve has been developed. Development and manufacturing of the microvalve are based on research results of the SFB 516, in particular those applicable to the drive unit, the silicon bulk micromachining, and the optimization of friction and wear.
