Conception d'un stimulateur destiné aux patients souffrant d'incontinence urinaire en utilisant la technologie MITEL 1.5 [micromètre]

Abstract

The aim of this thesis is to understand the physiological explanations behind the neural stimulation as well as the design and fabrication of a urinary incontinence prosthesis. This research work is divided into three main components. The first part explains the anatomy and functions of the nervous system as well as the electrical stimulation in general and in particular the stimulation of the bladder, spanning from the form of the stimuli waveforms over to the charge injection theory throughout the choice of stimulation sites. The second part explains the whole system of the urinary incontinence prosthesis as well as the full custom ICBSHURI microprocessor chip. The whole prosthesis is composed of three main parts: two external control devices and a surgically implanted part. The last part explains the hybrid circuit, which is carrying the microprocessor chip and different circuits needed for the functioning of the prosthesis."--Résumé abrégé par UMI.
