A balloon support (13) connecting two sections of a catheter tube (11 and 12). The balloon support (13) forms a rigid cage having an unobstructed pathway between the two catheter tube sections. The cage comprises openings (25) forming passages between the interior of the cage and a balloon chamber (22) formed between the cage and a balloon (14) surrounding the cage. The passages are sufficiently large not to significantly restrict the flow of a liquid through the passages and to substantially prevent pooling of liquid i n the balloon chamber (22). |
