ABSTRACT:
An appliance for draining bodily wastes from the natural bladder of a patient, or from an artificial bladder, through a surgically-created stoma, includes a tube insertable into the bladder through the stoma, and an inflatable balloon enclosing a substantial portion of the length of the tube. The balloon has a corrugated tubular portion terminating in a bulbous tip portion. The tip is located at the end of the tube to be received in the bladder, while the corrugated portion extends along the length of the tube which is received in the passage from the bladder created by the stoma. An inflation fluid is introduced into the interior of the balloon through an inlet in an external retainer plug and through fluid passages and ports in the tube. The balloon has an expandable wall which is thicker in the tip portion than in the corrugated portion, so that the corrugated portion can be substantially fully inflated before the tip portion inflates. The tip portion, when inflated, forms a donut-shaped cushion around the end of the tube in the bladder, while the corrugated portion inflates to provide a fluid-tight seal around the tube.
