14. A method for delivering a treatment substance to the inner ear of a recipient of an implantable medical device, comprising:
-
receiving, through the skin of the recipient, a user applied external force delivered to at least one resiliently flexible portion of the implantable medical device, wherein the at least one resiliently flexible portion forms part of a portion of the implantable medical device that is configured to have the treatment substance disposed therein, and wherein the user applied external force causes the at least one resiliently flexible portion of the implantable medical device to deform; and in response to the deformation of the at least one resiliently flexible portion of the implantable medical device, administering a portion of a treatment substance to the inner ear of the recipient. - View Dependent Claims (15, 16, 17, 18, 19)
