Abstract

This paper concerns the design and implementation of a new implantable Neuro-Monito-Stimulation System (NMSS) for the urinary tract rehabilitation in paraplegics. In addition to selective stimulation for voluntary micturition and permanent stimulation for reduction of the detrusor overactivity, the NMSS includes telemetry capabilities of electrodes-tissues contact. Resistance up to 10 kOmega could be measured with good linearity and sent wirelessly to an external controller at 1 kbps data transmission rate. With an embedded rechargeable battery, the implant lifetime is significantly extended up to 1000 cycles of 250 hours with nominal operating conditions. The NMSS design is described with the main system solutions and the preliminary experimental results.
