Hydrocephalus is characterized by an excessive accumulation of cerebrospinal fluid (CSF). Therapeutically, an artificial pressure relief valve (so-called shunt) is implanted which opens in case of increased intracranial pressure (ICP) and drains CSF into another body compartment. Today, available shunts are of a mechanical nature and drainage depends on the(More)
This paper presents a newly developed Transcutaneous Energy Transfer (TET) System to supply an electromechanical implant with energy. The system is capable of delivering a power of 1-5 W to the implant over a distance of up to 5 cm via an inductive link with a frequency of 100 kHz. Additionally, the inductive link incorporates a data link which allows(More)
Several models are available to simulate raised intracranial pressure (ICP) in hydrocephalus. However, the hydrodynamic effect of an implanted shunt has seldom been examined. In this study, the simple model of Ursino and Lodi [14]is extended to include (1) the effect of a typical ball-in-cone valve, (2) the effect of the size of the diameter of the(More)
