Claim Text:
1. A method of manufacturing an inflatable ear piece for a hearing aid, which inflatable ear piece is adapted to be inserted into an auditory canal of a user, the inflatable ear piece defining an inflatable cavity, which when inflated defines an inflated state in which the inflatable ear piece abuts an inner wall of the auditory canal, and when deflated defines a deflated state in which it allows for insertion and/or retraction of the inflatable ear piece from the auditory canal, the method comprising the steps of: providing the inflatable ear piece; providing a predetermined material in the inflatable cavity, wherein the predetermined material is a curable material; securing the curable material to an inner surface of the inflatable cavity, so as to bias the inflatable cavity away from a totally collapsed state, wherein the securing includes curing the curable material; and providing an inflation structure to allow air to be blown into the inflatable cavity after insertion of the inflatable ear piece into the auditory canal and configured to allow air to escape from the inflatable cavity.
