Presented herein are techniques for monitoring the physical state of a stimulating assembly to, for example, detect the occurrence of an adverse event. More specifically, an elongate stimulating assembly comprising a plurality of longitudinally spaced contacts is at least partially implanted into a recipient. Electrical measurements are performed at one or more of the plurality of contacts and the electrical measurements are evaluated relative to one another to determine the physical state of the stimulating assembly.

Presented herein are intra-operative techniques for setting the angular insertion depth of a stimulating assembly during implantation into a recipients cochlea. In certain embodiments, the angular insertion depth is monitored in real-time and advancement of the stimulating assembly is terminated when a selected angular insertion depth is achieved. In further embodiments, a linear insertion depth that corresponds to a selected angular insertion depth is intra-operatively calculated and advancement of the stimulating assembly is terminated when the calculated linear insertion depth is achieved.

An external portion of an auditory prosthesis includes magnets, electronics, and other components. In bone conduction auditory prostheses, reducing the amount of mass subject to vibrations in an auditory prosthesis has a positive effect on tuning of the device. One way of reducing such mass is to resiliently more massive components within the auditory prosthesis housing. Such resilient mounting reduces the dampening effect that these massive components have on vibrations generated by the prosthesis. When electronic components are suspended, feedback to said components is also reduced, resulting improved performance.

Disclosed are a medical implant system, components and method, in which one or more deformable elements are provided to provide a seal between the components of the medical implant system. In one aspect, the medical implant system comprises a fixture, an abutment and an abutment screw, and the deformable element is deformed upon tightening the abutment screw. The provision of the one or more seals reduces the risk of infection around the implant site.

An implantable hearing unit is provided that includes an implantable microphone, a rechargeable power storage device and a speech signal processor. The hearing unit further includes a signal coupling device that is adapted for electrical interconnection to an implantable auditory stimulation device, which is operative to stimulate an auditory component of a patient. Such a stimulation device may include cochlear implants, brain stem stimulation systems, auditory nerve stimulation systems, and middle or inner ear transducer systems. The signal coupling device is operative to provide processed drive signals from the signal processor to the stimulation device as well provide power from the power storage device to operate the stimulation device. In one arrangement, the signal coupling device is a wireless coupling between first and second coils. In such an arrangement, the hearing unit may be utilized with an existing implanted stimulation device to make that device a fully implanted hearing system.
