Abstract
A multifunctional device for insertion in an anatomical cavity through a narrow portal includes an expandable bladder, a body of fluid absorbing material carried by the bladder and a mechanism, which can be inflation or mechanical, for expanding the bladder. The device has a cross-sectional size in a compressed state with the fluid absorbing material in a dry state and the bladder contracted to facilitate insertion of the device through the portal. The fluid absorbing material is soft and expandable in a wet state upon absorption of body fluids in the anatomical cavity, and the bladder is movable via the expanding mechanism to move the device to an expanded state wherein the cross-sectional size of the device is increased. The bladder is movable to decrease the size of the device to facilitate withdrawal of the device from the anatomical cavity through the portal.
