Abstract
A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve. The sleeve includes an inflatable portion disposed about at least a portion of the circumference.
Claims19
An apparatus, comprising:
- a spring configured to form a closed loop, the spring being moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded, the spring defining a circumference while in the uncoiled configuration;
- an inflatable bladder coupled to the spring along at least a portion of the circumference;
- and
- an elongated inflatable chamber having a first end and a second end, the first end of the elongated inflatable chamber coupled to the inflatable bladder proximate a location along the circumference, the elongated inflatable chamber extending from its first end to its second end in a direction away from the location along the circumference.
