In-Vitro Evaluation of a Drainage Catheter with Integrated Bioimpedance Electrodes to Determine Ventricular Size

Abstract

Patients suffering from Hydrocephalus show an increased accumulation of cerebrospinal fluid, which needs to be drained into another body compartment by an im- planted shunt. To prevent from over-drainage, which some- times still occurs despite improvements in shunt technology, a possible future shunt could contain sensors and supervise the ventricular size electrically. This work approaches this and presents the in vitro study of a drainage catheter with integrated bioimpedance evaluation capabilities.
