Problems solved by technology

It is also difficult to maintain the splint in the desired position relative to the bandage and cochlear implant during wrapping, especially if the patient has bilateral cochlear implants
In addition to the inconvenience during MRI procedures and possible magnet rotation, delays associated with slipping bandages and incorrectly positioned splints prevent effective use of the MRI system

Embodiment Construction

[0032] The following is a detailed description of the best presently known modes of carrying out the invention. The description is not limiting, but merely made for the purpose of illustrating the general principles of the invention.

[0033] An example of a device for resisting torque applied to a cochlear implant magnet (or "device") according to the present invention is found in Figure 4The center is indicated generally by the reference numeral 100 . The exemplary device 100 includes a first splint 102 and a second splint 102 and a strap system 104 to maintain the splints in their intended positions. As discussed in more detail below, the configuration of the strap system 104 allows the straps that pull the splint 102 against the head (i.e., against the hair, and against the skull despite having a thin layer of skin in between) to be Tighten enough to hold the magnet in place without sliding up towards the top of the head and to maintain the splint in the desired position...

Abstract

An apparatus, for use with a cochlear implant having a magnet and implanted within a patient having first and second ears, includes a first splint and a strap system, including at least a forehead strap and a chin strap, configured to position the first splint behind the first ear.

Description

technical field [0001] The present disclosure generally relates to implantable portions of implantable cochlear stimulation (or "ICS") systems. Background technique [0002] The ICS system is used to help deeply deaf people perceive the sensation of sound by directly stimulating the intact auditory nerve with controlled electrical pulses. Ambient sound pressure waves are picked up by externally worn microphones and converted into electrical signals. The electrical signals are in turn processed by the sound processor and converted into pulse trains of varying pulse width, rate and / or amplitude and transmitted to the implanted receiver circuitry of the ICS system. The implanted receiver circuit is connected to an array of implantable electrodes that have been inserted into the cochlea of ​​the inner ear, and electrical stimulation current is applied to the different combinations of electrodes to produce the perception of sound. Alternatively, the electrode array can be inser...
