摘要： An implantable magnet that can freely turn in response to an external magnetic field, thus avoiding torque and demagnetization on the implantable magnet. The implantable magnet can be combined with an electric switching function depending on the orientation of an external magnetic field, thus protecting an implanted coil and/or implant electronics against induction of over-voltage or performing an electric switching function for other various purposes. The magnetic switch may further include, for example, a first switching contact and a second switching contact. A magnetically soft body that includes an electrically conductive surface is shiftable between a first position where the body is in simultaneous contact with the first and second switching contacts, and a second position where the body is out of contact with at least one of the first and second switching contacts. The body and the implantable magnet are positioned such that the body is shifted to one of the first position and the second position as a function of the external magnetic field resulting in a magnetic force between the magnet and the magnetically soft body.

摘要： A low-power implant system. The system includes an implant for implantation into a person, such as a cochlear implant or a middle ear implant. The implant is capable of communicating with a device via transmission of ultra wideband pulses. The device may be adapted to be worn external to the person, or may be a second implant. So as to conserve battery power, the transmitted ultra wideband pulses may have a low duty cycle of approximately 1/1000 or less. Power savings may also be realized by using time-gating amplifiers in the implant and/or device receiver.

摘要： A hearing enhancement includes an audio processor that generates an electrical audio signal and transmits the signal to a coil. The coil is implanted into a patient in a position that results in transmission of mechanical stimulation to the inner ear when the coil is spatially displaced. A permanent magnet is placed in proximity to the coil so that when the coil receives the electrical audio signal form the processor, the induced coil magnetic field in the coil interacts with the magnetic field from the permanent magnet to spatially displace the coil and, as a result, transmit the mechanical stimulation to the inner ear.

摘要： A cochlear implant system has an external housing adapted for placement at a specific location on the external skin of a user. The external housing includes (i) a signal processing module for converting an incoming acoustic signal into a representative electrical information signal, and (ii) a signal transmission module for transmitting across the skin of the user an electrical power signal representative of the electrical information signal. An implanted portion receives the electrical power signal and produces for the auditory system of the user an electrical stimulation signal representative of the acoustic signal. The external housing and the implanted portion magnetically cooperate so as to hold the external housing in place at the specific location without structural interaction with the outer ear of the user.

摘要： Interference-free coil systems are coil systems having at least two coils which are identical in terms of inductance. These coils are arranged such that their magnetic fields are antiparallel to one another. Consequently, induced voltages within the coils are substantially eliminated when the coils are exposed to a homogeneous electromagnetic field. If exposed to an nonhomogeneous electromagnetic field, however, a net voltage is induced and enables the extraction of data and power. Reed switch configurations in the implantable prostheses protect against induced voltages caused by the radio frequency field generated by an MR imager when the reed switches are mounted parallel to the plane of a receiver. Reed switch configuration may be used to disconnect, de-tune, or short circuit a receiver. For example, they may be used to disconnect the receiver diodes. Some magnet configurations reduce torque caused by an external magnetic field and prevent demagnetization when disposed within, outside, or partially within an implantable prosthesis. Magnets which align with the external magnetic field also reduce the torque caused by the field and prevent demagnetization.
