A cochlear implant is a surgically implanted electronic device that is inserted into the cochlea and utilizes electrodes to stimulate various portions of the inner ear to transmit the proper coding signals to the auditory nerve and into the higher auditory pathways of the brain. ...
Replacement of a cochlear implant and/or its external components is considered medically necessary when the existing device is not functional and cannot be repaired, or when replacement is required because a change in the member's condition makes the present unit non-functional and improvement is ex...
ReplacementNucleusObjective and importanceWe recount the unusual case of a young boy whose removable cochlear implant magnet extruded through the skin after becoming displaced after several episodes of direct but minor head trauma.This article outlines a course of clinical management that resulted in the...
Cochlear implant (CI) users typically achieve satisfactory speech intelligibility in quiet environments such as a sound booth used for testing in audiology clinics. However, they encounter difficulty hearing and comprehending speech in noisy social settings. There have been significant efforts towards the ...
In this case, the hearing loss can be alleviated by providing an artificial electrical stimulation, in replacement of the firing of hair cells. Cochlear implants have been developed based on the fact. A cochlear implant is an electronic device surgically implanted into the body that provides a ...
the connector being permanently attached to the electrodes and ideally never requiring replacement. Silastic sheet 36 contains 22 preformed platinum parts 30 which mate with the feedthroughs on the ceramic plate 32. The preformed parts in FIG. 3 are shown as terminating in spheres, although in FIG...
Although, the current implant technology recovers the patient from deafness by using external electrodes implanted in Cochlea but it suffers from several drawbacks such as the need for frequent battery charging/replacement, need for wearing external components and the risk of damage when exposed to an...
it’s a bigger problem than failure of external parts. Removal of the faulty implant andreplacementwith a new one is a standard course of action. That means another major surgery. There is also a risk the new implant won’t work as well as the old. However, with improved surgical techniq...
Both cochlear implant circuits24,25 primarily focus on front-end signal conditioning and lack a comprehensive neural stimulation unit, essential for evoking responses from auditory neurons. Power consumption is the most critical design factor for FICI systems since battery replacement of an implantable ...
