An electrode arrangement is described for sensing electrical activity in target tissue. An inner electrode has an elongate electrode body formed as a cylindrical section with an inner penetrating end for insertion into the stapedius muscle target tissue. An outer electrode fits over the inner electrode and an outer penetrating end for insertion into the target tissue. The two electrodes are joined together with their electrode bodies in parallel so that the penetrating ends of the electrodes penetrate in the same direction into the target tissue to sense electrical activity in the target tissue.

An implantable fixation structure includes a c-shape bone fixation clip adapted to fit over and attach to a bony bridge element in the middle ear of a patient. A c-shape electrode fixation clip is adapted to fit over and attach to an electrode array element in the middle ear of the patient. A connecting bar has a first end connected to the bone fixation clip and a second end connected to the electrode fixation clip. A coupling clip is connected to the connecting bar between the first end and the second end and adapted to fit over and attach to a cochlear implant element and hold the cochlear implant element in a desired position relative to the middle ear of the patient.

Middle ear fixation structure

An implantable fixation structure includes at least one implantable holding element. The holding element is connected to an implantable cochlear implant element and maintains the cochlear implant element in a desired position relative to the middle ear of a patient user.
