Abstract :
Presents a new implantable microstimulator system for neuromuscular stimulation. The implantable circuitry is externally controlled and powered by a single encoded radio frequency carrier and may have up to 16 independently controlled bipolar channels. The implant system is adaptable to the patient´s needs and to future development in stimulation algorithms, without changing the implant. The microstimulator is able to generate a wide range of stimulation patterns including selective stimulation waveforms. An optical telemetry link transmits the state of patient to the external controller. The chip has been designed for structural testability and uses circuit techniques to reduce power consumption and insure long-term stability. The implantable system can be used to any neuromuscular applications. If is intended to restore normal bladder functions (retention and incontinence) to spinal cord injured (SCI) patients
