Implantable neuro-monito-stimulation system dedicated to enhance the bladder functions

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 10kΩ could be measured with good linearity and sent wirelessly to an external controller at 1 kbps data transmission rate. With an… Show more

“…Note that, given a concrete I L value, it is not possible to obtain regulated output voltage values (V out [1]REG, V out [2]REG ) greater than the values that would be obtained in an unregulated scenario (V out [1], V out [2] ). Hence, both unregulated V out[n] curves (Fig.…”

“…Thus, it can be stated that, ideally, the cascade connection of n ideal TPVD circuits with Vin[n] = Vout[n- 1] leads to a situation where Vout[n] = 2nVin [1]. Hence, theoretically, a 2-stage (n = 2) cascade connection of TPVD circuits using a 3.3 V battery as input voltage Vin [1] would provide an output voltage Vout [2] = 13.2 V. Actually, the real output voltage V out that can be obtained through the single-stage TPVD architecture depends on many design/application parameters and usually is lower than the result given by the ideal analysis. The size (W k /L k ) of the S k transistors, which is directly related to their on-resistance R dsk values and their parasitic capacitances, the values of C f and C L capacitors, the switching frequency f s = 1/T of CLK k clock signals, the input voltage V in , and the value of the active load R L (which sets the load current I L ) are parameters that have a direct influence in the unregulated steady-state V out value that is really obtained.…”
