ABSTRACT:
An improved construction for an expandable and contractible retention member, such as a balloon, for body access tubes, to retain a distal open end of the tube against an inner body cavity wall of the patient. The balloon is secured to only the inner and outer peripheral edges of the distal open end of the tube by a sleeve. The sleeve has both an outer wall and an inner wall which receives, respectively, the outer and inner walls of the tube. The balloon includes an outer wall and an inner wall which defines an inflation chamber. The inflation chamber extends beyond the distal open end of the tube so that no portion of the tube passes through the chamber. The balloon includes an axial opening to permit passage of fluid out of the tube.
