Özet:

 

This paper covers circuits and systems techniques for the  construction of high reliability biosensing and neurostimulation smart  medical devices.  Such microsystems are dedicated for interconnections  through the peripheral neural systems.  Case study related to  applications such as bladder control is discussed.  Available  electrical neurostimulation techniques for the rehabilitation of  urinary bladder functions do not allow an adequate voiding due to  dyssynergia between the bladder and the sphincter.  A new implantable  stimulator, built with commercially available electronic components,  was designed to overcome these difficulties.  The proposed system  performs two types of stimulations: Selective Stimulation for bladder  voiding and Permanent Stimulation to reduce the bladder overactivity  symptoms.  Also, a fully integrated extended version of the stimulator  is achieved with the additional ability to monitor the  electrodes-nerve contact impedance variations in order to detect  electrodes faults or nerve physiology changes.  The implemented full  custom device provides a reliable stimulation technique and addresses  the lack of features (programmable parameters, user-friendly interface  and waveform flexibility) of the previous stimulation devices.  Experimental results of the fabricated chip confirm its functionality.  The microstimulator generates a wide range of stimuli waveforms with  variable parameters and its modular architecture makes it an  expandable multichannel stimulation system.
