Development of a New Implantable System for Functional Electrical Stimulation in Sendai Fes Project
نویسندگان
چکیده
We developed a new implantable FES system with 32 output channels. In this system, a RF coil utilizing amorphous magnetic fibers was introduced for increasing transmission efficiency of this telemeter system which transmitted currents for electric power supply to the implanted system and for applying electrical stimulation to the paralyzed muscles. A helically coiled 19 strand rope wound from ultrafine NAS106 stainless steel wires was used as an implantable electrode. The fatigue resistance of this helical NAS106 electrode was much higher than that of the SUS316L electrode which we developed as a percutaneous intra-muscular electrode. We implanted this telemetry system and electrodes to the hindlimbs of three healthy dogs in order to investigate transmission efficiency of the telemeter system and feasibility of this FES system with NAS106 electrodes under the implanted condition.

Clinical experience of functional electrical stimulation for restoration of tetraplegic hand function
There are some Functional Electrical Stimulation (FES) systems that restore upper limb functions in tetraplegia. Surface electrodes [1], percutaneous intramuscular electrodes [2] and totally implantable electrodes [3] are used for stimulation in these neuroprostheses. The FESMATE system, developed by the Sendai FES Projects in Japan, is a portable multi-channel FES system with percutaneous elec...

متن کاملDrop foot treatment: Functional electrical stimulation
Background: The gait pattern after stroke can be disturbed by foot drop. The conventional approach to the treatment of drop foot gait is a splint, the ankle-foot orthosis (AFO). An active approach is functional electrical stimulation (FES). Functional electrical stimulation (FES) refers to electrical stimulation of muscles in order to improve the impaired motor function. This is achieved by act...
