Apparatus for the treatment of volume deficiency disorders of body structures and related syndromes and, more particularly, apparatus that deliver fluid via a catheter at a controlled pressure into a balloon situated within or adjacent a body cavity to effect tissue expansion. A drainage mechanism, especially useful in treating bladder deficiencies, is disclosed which permits drainage of body fluids while the balloon is in its expanded state. The balloon can be adapted to fit within a recess of the catheter, for example, in a folded or rolled state, and the invention also provides means for delivering fluid at a controlled pressure into an inflatable balloon. |
