A hand-actuated retention catheter, comprising a tube having a distal end, and and outer andninner surfaces, the inner surface defining an inner lumen , an overcoat layer encircling thentube, the overcoat layer having an interior surface, a cavity interposed between the tubenand the overcoat layer , said cavity encircling the tube and being defined by portions of thenouter surface of the tube in cooperation with portions of the interior surface of the overcoatnlayer , a restriction means; wherein the overcoat layer includes an expandable resilient balloonnsection proximate the distal end, a fluid reservoir section proximal thereto, and a catheternsleeve section interconnecting said balloon section and said reservoir section, saidnhand-actuated retention catheter further comprising a means for limiting the lateral ballooningnof the reservoir section ; said means for limiting lateral ballooning encircling the reservoirnsection to limit the lateral ballooning thereof, said means for limiting lateral ballooning notnsubstantially restricting the flow of fluid from the balloon portion to the fluid reservoir portionnof the cavity . |
