Abstract
An implantable electrode arrangement for a cochlear implant system includes an elongated electrode array for insertion into a patient cochlea. A fluid delivery channel is located within the electrode array parallel to a central longitudinal axis with at least one fluid delivery port for delivering lubricant fluid from the fluid delivery channel to the outer surface of the electrode array. The fluid delivery port and the lubricant fluid are configured to produce a lubrication region close to the outer surface of the electrode array proximal to the fluid delivery port during insertion of the electrode array into the patient cochlea so as to reduce insertion resistance at an adjacent section of lateral wall of the patient cochlea.
