摘要:
An ear implant electrode device is described. An implantable electrode array has an outer surface with electrode contacts for electrically stimulating adjacent neural tissue. There is a fluid delivery channel within the electrode array for delivering a therapeutic fluid through one or more fluid delivery ports on the outer surface. A temporary fill tube is connected to the fluid delivery channel for providing the therapeutic fluid when the electrode array is partially inserted into a patient neural tissue without being functional after the electrode array is fully inserted. At least a portion of the fill tube is adapted for removal after providing the therapeutic fluid to have the fluid delivery channel and any remaining portion of the fill tube completely enclosed within the neural tissue after the electrode array has been fully inserted so as to leave no exposed fluid opening outside the neural tissue.
