ELECTROMAGNETIC BONE CONDUCTION HEARING DEVICE

摘要

An implantable hearing prosthesis for a recipient patient is described. An implantable attachment magnet is fixable beneath the skin of the patient to underlying skull bone and is adapted to magnetically connect with an external attachment magnet over the skin. An implantable signal transducer also is fixable beneath the skin of the patient to underlying skull bone and is adapted to transform a magnetic audio signal from an external signal drive coil into a corresponding mechanical stimulation signal for delivery by bone conduction of the skull bone as an audio signal to the cochlea. A connector member flexibly connects and positions the attachment magnet a fixed distance from the signal transducer.
