Abstract: | A new implantable bladder volume-monitoring device based on the impedance measurement of the detrusor muscle is described.
The system is completely autonomous and forms a mixed-signal (analogue/digital) feedback loop with a neuro-stimulator to rectify
bladder dysfunctions (incontinence and retention) through neuromuscular stimulation techniques. A programmable instrumentation
amplifier and a signal processing block, to eliminate the artefacts caused by the patient’s movements, have been designed
and tested. The layout for the signal processing block has been realised in 0.8 μm BiCMOS technology. |
