摘要:
At least one exemplary embodiment is directed to a system configured to occlude an ear canal. The system comprises a support structure, an expandable device, a housing, a resilient reservoir, and a threaded device. Resilient reservoir resides within housing and is filled with a medium. The threaded device couples to a threaded region of support structure. Threaded device fits in an opening of housing. Rotating threaded device reduces an interior volume of housing thereby transferring the medium from resilient reservoir to expandable device. Threaded device is rotated to displace sufficient medium within resilient reservoir to expand expandable device to occlude the ear canal. Resilient reservoir is passively filled when expandable device is in an un-expanded state.
