Patent abstract
An expandable device (1100) can be configured to occlude an ear canal to isolate an ear canal volume from an ambient environment. The expandable device includes a support structure (1102). A membrane having a proximal end and a distal end is attached at each end around the support structure (1102) forming an expandable element (1104). The expandable element (1104) has an expanded state and an un-expanded state. The expandable element is adjacent to the support structure (1102) in the un-expanded state. The expandable element (1104) in the un-expanded state minimizes an insert profile of the expandable device (1102).
