Abstract
A device includes a balloon inflation module having an involuted balloon housed within a lumen, an integrated reservoir in fluid communication with the involuted balloon where the balloon inflation module is configured to selectively displace a volume of fluid from the integrated reservoir into the involuted balloon and from the involuted balloon into the integrated reservoir. The device also includes a port configured to receive an accessory module. In one embodiment, the accessory module is a communication module having a logic circuit coupled to an ambient microphone configured to pick up ambient audio content, an ear canal microphone configured to pick up audio in the proximity of an ear canal, and an ear canal receiver configured to provide audio content in the proximity of the ear canal. In some embodiments, the integrated reservoir is formed within portions of a push button spring-loaded pump assembly. Other embodiments are disclosed.
