Low-cost, four-channel cochlear implant
TLDR
A low-cost, four-channel cochlear stimulation system utilizes a completely passive, implantable receiver/electrode array that is inductively coupled to an external wearable processor as mentioned in this paper.Abstract:
A low-cost, four-channel cochlear stimulation system utilizes a completely passive, implantable receiver/electrode array that is inductively coupled to an external wearable processor. The receiver/electrode array is formed in a silicone rubber carrier adapted to be implanted in a deaf patient. At one end of the receiver/electrode array, positioned subcutaneously near the surface of skin above the ear, four receiving coils are arranged in an appropriate pattern. Such receiving coils are held within an hermetically-sealed titanium case. At the other end of the receiver/electrode array, which may be pre-formed in a spiral to match the basal turn of the cochlea, and which is inserted in the cochlea, four ball electrodes are spaced apart along an inner radius of the spiral. Each electrode is electrically connected to a respective receiving coil. Each receiving coil is also electrically connected to a reference electrode typically located near the receiver-coil end of the array. The wearable processor senses audible sounds, converts the sensed sounds to corresponding electrical signals, and splits the electrical signals into four frequency bands or channels. A speech processing strategy applies the processed signals of each channel to each of four external coils, as a series of biphasic current pulses. The four external coils are aligned, using a suitable headpiece, with corresponding coils of the receiver/electrode array, thereby inductively coupling the biphasic current to a respective electrode of the implanted electrode array.read more
