In an embodiment, an ejection mechanism includes an inflatable device with an inflatable object (e.g., a silicone impregnated or other airbag, etc.) that is folded back inwardly on itself into an interior space of the inflatable object (e.g., forming a convolution, etc.) to envelop an item for ejection from a tube. In order to eject the item, gas enters the inflatable device to facilitate expansion of the inflatable object. The tube structure withstands the pressure loading as does the convolution of the inflatable object. Due to the tube limiting the expansion, the inflatable object rolls against the tube inner surface as it expands to move and/or eject the item from the tube. The inflatable device may further include an inflatable object (e.g., one or more airbags, etc.) in a telescopic arrangement with inflatable telescopic or nested stages (or convolutions) to eject or release the item.
