Abstract: A device that can be used to obliterate a cavity comprising a proximal segment comprising a proximal end; a distal segment comprising a plurality of microcatheters attached to the external surface of the inner balloon layer, each microcatheter comprising a plurality of perforations; an intermediate segment between the proximal segment and the distal segment; a connector on the proximal end of the proximal segment, the connector comprising a balloon layer inflation and deflation port and further comprising an adhesive delivery port; an inflation and deflation lumen connecting the inflation and deflation port with the inner balloon layer; an adhesive delivery lumen connecting the adhesive delivery port with the plurality of microcatheters; a self-sealing valve connected to the inflation and deflation lumen; and a separation area between the distal segment and the intermediate segment configured to separate the distal segment from the intermediate segment.

Abstract: A drainage device comprising a) a drain comprising a proximal end, a distal end and a central lumen; and b) an occlusion removing structure within the central lumen of the drain comprising a proximal end and a distal end; where the proximal end of the drain comprises an adaptor; where the distal end of the drain comprises a plurality of apertures; where the proximal end of the occlusion removing structure is a connector configured to mate with the adaptor; where the distal end of the occlusion removing structure is a tubular mesh; where the tubular mesh extends substantially throughout the length of the drain from the proximal end of the drain, to the distal end of the drain; and where the occlusion removing structure is axially removable from the drain.
